Product Detail

Thru-hole components allow the KD-8 PCBs to be quickly and easily configuration for different applications.

Product Summary

Price: $350.00 and up

Multiple KD8s can be networked together using 6-pin RJ11 (phone-type) jacks.  


The KD-8 has eight heavy-duty outputs that can directly drive seloniods up to 120w each (12v @10 Amps max or 24v @ 5 Amps max).


The KD-8 can be configured with a Voltage_Doubler.  The Voltage_Doubler is useful for battery operation and allows 12v solenoids to be driven from power supplies as low as 7v.


Each KD8 output is given its own unique address for PC/Host control.  These addresses are stored in EEPROM and can be easily change for networks containing multiple KD8 PCBs.  One (or multiple) PC/Host(s) can can control all the KD8’s outputs via a RS-232 (or optional USB) interface.  See document “Message Flow Release 6”.
