Isolated digital I/O board fits PC/104 format
The ISM-TRM-COMBO provides a combination of eight optically isolated inputs, eight optically isolated outputs, and eight Form C relays on one board. Every input line is optically isolated from the others and from the computer interface circuits with a 2500V isolation voltage rating.
Inputs support either an active high or active low signal from 5 to 30 volts. Each input has a contact bounce eliminator. Each output has a NPN Darlington transistor pair with an clamp diode for switching inductive loads and can handle 500 mA and 30 V. There are also eight independent SPDT Form C relays that can handle 6A at 250 Vac/24 Vdc. The 3.6 x 3.8 inch boards have the same mounting hole pattern as PC/104 modules.
