K E Y F E AT U R E S :

PC/104 utility board featuring eight opti -

cally isolated digital inputs with Change of

State (COS) detection, eight TTL inputs and

eight electromechanical 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 iso -

lating the digital inputs from each other, and

from the computer, assures smooth, error-

free data transmission in noisy, real-world

environments.

useful for reading dry contact closures or any

TTL-compatible outputs, are also provided.

The eight electromechanical relays are de-

energized at system power-up to prevent an

unintended control output signal. Data to the

relays are latched. The 24-channels are avail -

able via one 50-pin IDC type header.

are software controlled, enabling the board

to generate an interrupt whenever one or

more of the isolated digital inputs changes

determine their status, then the interrupt is
