8 Channel Relay Output

The D-111 is a digital signal conditioning card that takes TTL outputs from an STE I/O bus and feeds them through buffers to the relays. The relay outputs are connected to a DIN type 'F' connector

D-110 SPCO @ 10 Amp

D-111 DPCO @ 5 Amp

Opto Isolated Output

The D-130 is a digital signal conditioning output card which takes TTL compatible outputs from an STE I/O connector and feeds them through opto couplers to power triacs.

D-130 @ 6 Amps

D-131 @ 1 Amp

Contact Detector

The D-140 is a digital signal conditioning input card that detects voltage inputs and buffers them through to a standard STE I/O connector. Series input resistors extend the input range to 100 Volts.
