Bipolar Stepper Motor Driver

(Full Documentation in pdf Format) 
 

bb248.jpg
Bipolar Stepper Motor Driver
Is a new replacement card for the old KT5158 or K158 card. The new card features
 - 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 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 Isolated I/O Module (kit)
 
8-Relay Module (mains rated - 110V and 250VAC.) An extension of our Kit CPS74 (see next kit), PC controlled 8-Relay Board with 250V switching relays and added features. It is in a plastic case, latched relay operation, 250V relays switched in safety by using Dinkle connectors, and with 4 external inputs. Uses serial port so it can be located over 100 yards from the PC. Comes with case and end panel pieces as shown in the photos. Requires a center positive 9-to-12V DC power supply, at least 500mA, 2.5mm jack. (CPS108)

Upgrade K108 - join two k108 together
 
CPS108/CPA108 has been a good seller. This kit is to connect two of them together to give 6 Inputs and 16 Relay Outputs. All you have to do is change the firmware, change the front & back panels, and jumper out 2 ICs.

PC Printer Port Relay Board (Assembled) (version 2)
 
Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect a DB25 straight trough cable from computer to DB25 connector on the relay board. There are 8 relays each capable of switching 12VDC/10A or 240VAC/5A. Each relay has an LED to indicate when it is operated. We provide two sets of complete, stand-alone software to control the relays: one works under DOS so you can write your own batch files to control individual relays, the other works under Windows. Needs 12VDC center positive 2.5mm power supply. PCB Size 6.75" x 2.75" (CPA74)

Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect printer cable from computer to Centronics connector on relay board. There are 8 relays each capable of switching 12VDC/10A or 240VAC/5A. Each relay has an LED to indicate when it is operated. We provide two sets of complete, stand-alone software to control the relays: one works under DOS so you can write your own batch files to control individual relays, the other under Windows 3.1. Needs 12VDC center positive 2.5mm power supply. PCB Size 6.75" x 2.75" (version 2) (CPS74)

Parallel port output module (V2) (Assembled)
 
Once stock on hand is sold out for this item, it will no longer be available as pre-assembled. It will still be available as a kit requiring soldering.

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)
