Our Parallel Port Relay card allows you to control stepper motor operations
from your parallel port. It uses a 74HC245 buffer IC to provide protection
for your PC’s parallel port and provide enough current drive for turning on
and off opto-isolator inputs. Can be connected to our KTA-191, KTA-196 and KTA-179 stepper motor driver cards. The card provides 8 motor control output signals ( 4 Step signals, 4 Direction signals) to control up to 4 Stepper Motor Drivers, 4 digital inputs designed for use as limit switch inputs, 2 Relay Outputs to control spindles, coolant or vacuums, and 3 general IO which are connected directly to the port. The card is available with 12V or 24V relays and requires power at the relay voltage. Fitted with screw terminals. Perfect for a 3 axis or 4 axis CNC machine.
You can also use it in other applications for I/O control from your parallel port
Finished Dimensions (mm): 58Wx88Lx25H

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)

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)
