Parallel port output module (V2) (Assembled)

This is our Kit 74V2 but put into a box with top quality Dinkle connectors to the relays. With the rapid progress in computer technology many people now have a surplus computer just gathering dust somewhere. Thus these computers are free to be used as dedicated controllers for a variety of uses: turning on/off lights or other devices around the home, office, laboratory or factory come to mind. All that is needed is the interface to connect it to the real world. (CPA165)

DS1820 TO92 IC

The DS1820 Digital Thermometer provides 9–bit temperature readings which indicate the temperature of the device. Information is sent to/from the DS1820 over a 1–Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS1820. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source. Because each DS1820 contains a unique silicon serial number, multiple DS1820s can exist on the same 1–Wire bus. This allows for placing temperature sensors in many different places. Applications
where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.

PC Serial Port Stepper Motor Interface Card

PC Serial Port Stepper Motor Interface Card
NOW MUCH FASTER - Up to 6.3kHz Stepping Rates
SIMULTANEOUS MOTOR CONTROL ADDED
Connects to the PC serial port and provides an easy to use interface for connecting and controlling stepper motors by your PC. You can multidrop up to 4 interface cards off the 1 RS232 serial line so you can control up to a total of 16 stepper motors.

You simply write ascii commands through the PC's serial port to the card to control each of the stepper motors. A free PC program (source code in VB is included) is provided so that you can execute a number of commands and repeat the process

Examples of the commands are

    @01 AMOV 1000 2000 n 4000 do an absolute move of stepper 1,2 and 4 to positions 1000, 2000 and 4000
    @01 AMOV 2000 do an absolute move of stepper 1 to position 2000
    @02 RMOV -400 do a relative move of stepper 2 400 steps backwards
    @03 POSN 10000 indicate stepper 3 is at position 1000
    @04 STOP stop stepper 4
    @01 STAT   card sends the status of motors 1 to 4 whether they are moving or not and status of limit switches.

Positions can be between -99999999 and 99999999 steps. The user can also set the acceleration and deceleration rates when starting and ending a sequence of steps. Limit switch inputs are available for each of the motors to prevent motors moving out of range.

- screw Terminals for all inputs, power connections and motor connections.
- Full and Half Step (less resonance problems) operation and microstepping of 4,8,16,32,64 and 128 operation
- Step and Direction Inputs.
- an enable input which will remove all power to the motor

We tested the KT5196 against a K158 and found an increase of 33% in stepping rate performance. The KT5196 is able to drive 4 wire (and 6 or 8 wire) bipolar stepper motors at up to 8 amps
Please note there is not inbuilt current limiting for the coil currents

Dimensions 75x105x20mm

A CD containing a visual basic program and source code which controls up to 4 motors from a parallel port is included.

Serial Bipolar Stepper Motor Driver

Serial Bipolar Stepper Motor Driver
Is a combination of our popular KT5190 Serial Stepper Controller and the KT-5196 Bipolar Stepper Motor Driver.
You simply write ascii commands through the PC's serial port to the card to control each of the stepper motors

Examples of the commands are
    @01 AMOV 2000 do an absolute move of stepper 1 to position 2000
    @02 RMOV -400 do a relative move of stepper 2 400 steps backwards
    @03 POSN 10000 indicate stepper 3 is at position 1000
    @04 STOP stop stepper 4
    @01 STAT   card sends the status of motors 1 to 4 whether they are moving or not and status of limit switches.

Positions can be between -99999999 and 99999999 steps.

The new card features
- accepts the same serial ASCII commands as the KT-5190 to drive the motor eg @01 RMOV 10000
- accelerate and decelerate motors
- control up to 4 KT-5197's from the one RS232 serial port
- accepts a 0-5V signal to control the speed of the stepper motor.
- a double sided PCB (more reliable and no links to solder).
- screw Terminals for all inputs, power connections and motor connections.
- Full and Half Step (less resonance problems) operation
- Step and Direction Input.
- an enable input which will remove all power to the motor

The KT5197 is able to drive 4 wire (and 6 or 8 wire) bipolar stepper motors at up to 8 amps
Please note there is not inbuilt current limiting for the coil currents

Dual Bidirectional DC Motor Speed Controller

Dual Bidirectional DC Motor Speed Controller
This Motor Speed Controller allows a user to control the speed of up to two DC Motors independently, using an analog 0-5V signal, potentiometers, serial port of a PC or 1-2mS RC Pulse.
Modes of Operation:
The KT-5198 can be operated in serial, analog or pulse mode. In analog and pulse modes each motor can be operated in unidirectional mode with the 0-5V analog input (or 1-2mS pulse) giving 0-100% PWM and a digital input for direction selection, or in bidirectional mode where the analog or pulse input is responsible for both direction and speed selection.
In bidirectional mode 2.5V (or 1.5mS pulse) will give 0% PWM duty, increasing voltage from 2.5V to 5V (or pulses from 1.5 to 2mS) will increase the PWM duty from 0-100% and turn the motor in one direction. Decreasing the voltage from 2.5V to 0V (or pulses from 1.5 to 1mS) will increase the PWM duty from 0-100% and turn the motor in the other direction.

The PWM frequency can be set by a serially command to 10KHz, 1.25KHz and 156Hz
The maximum voltage available to run the motor is 50VDC.
Current: The IRFZ44 MOSFET can handle 49A; the IRF4905 can handle 74A. However the PCB tracks that run from the MOSFET pins to the screw terminal block can only handle around 10A. When running the motor check the temperature of the MOSFETs to see if heatsinks are required.

RC Servo Motor Controller

RC Servo Motor Controller
The Ocean Controls RC Servo Motor Controller will control up to 8 servo motors. 4 of the servo motors are controlled by ASCII RS232 serial commands. This can be increased to 8 by the configuration command WRCF.
The form of the serial command is @xx WRSP yyy where xx is the address of the motor and yyy is the position which can vary between 0 and 200.

The other 4 servo motors are controlled by the position of a switch. A switch is connected between the Lx and COM inputs. The user then writes a series of commands to the controller to tell what positions the motor is to move to when the switch is in the OPEN and CLOSED states. The user can also set the rate of movement between the OPEN and CLOSED positions. These variables are automatically saved in EEPROM so that they will not be lost on loss of power.

Power Supply Required: 9 to 24V DC

Programmable Stepper Motor Controller (old version)

Programmable Stepper Motor Controller is a four axis multifunction programmable stepper motor controller which utilises the modbus protocol for communications. The Modbus Programmable Stepper Motor Controller is designed for use as an alternative to an expensive PLC for simple process type applications. It can be used as a standalone controller to control up to 4 stepper motors and I/O or in conjunction with a PLC to control stepper motors Using a PC and the supplied program “StepModb” a user can develop a program and then download it via a RS232 serial link, into the controllers non volatile (EEPROM) memory. Alternatively the controller can be controlled via a PLC using the modbus protocol. The controller communicates at 9600 baud, 8 data, Even Parity and 1 Stop bit.

This is the older version. Limited Qty available. Super low price!

4-Channel Temperature Monitor and Control

This kit is an extension of our popular K145 Temperature Logger kit. Like the K145 it features 4 temperature inputs using the DS1820 digital sensor. We have also added 4 relays to provide output control. Commands for reading temperatures or controlling relays are sent via the RS232 serial interface using simple text strings. The kit can be controlled by a simple terminal or communications program (such as Hyperterminal) or via the free Windows software available for the kit. This software provides basic thermostat and temperature logging functions. This kit includes 1 x DS1820
