104-II-16

K E Y F E AT U R E S :

32-channel PC/104 utility board featuring 16

optically isolated digital inputs with change

of state (COS) detection and 16 electrome -

chanical Form C SPDT relay outputs. The

isolated, non polarized inputs may be driven

by either DC sources of 3-31V (or higher by

special order) or AC sources at frequencies of

40Hz to 10KHz. Optically isolating the digital

inputs from each other, and from the comput -

er, assures smooth, error-free data transmis -

sion in noisy, real-world environments. The

input channels are available via a 34-pin

IDC type header. The 16 electromechanical

relays are de-energized at system power-up

to prevent an unintended control output

signal. Data to the relays are latched. The

relay contacts are available via a 50-pin IDC

type header.

16 optically-isolated, non-polarized CMOS compatible

digital inputs accept ±31VDC or AC rms

IRQ on input change of state (COS) eliminates the need for

constant polling

Slow/

noisy DC inputs

16 Form C electro-mechanical relays switch up to 1A each

The Model 104-IIRO-16 is a low cost

are software controlled, enabling the board to

generate an interrupt whenever one or more

of the isolated digital inputs changes state.

This eliminates the need for constant polling
