K E Y F E AT U R E S :

utility board featuring 32 optically isolated

digital inputs with change of state (COS)

interrupt generation and 4 handy electrome -

chanical relay outputs. The board provides

connections to an assortment of devices

including sensors, switches, controllers,

powered circuits, and other user inputs. The

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 computer, assures

smooth, error-free data transmission in noisy,

real-world environments. The 104-II32-4RO

can be used in a variety of PC/104 applica -

tions such as embedded SCADA systems,

industrial automation, process control, scien -

The 104-II32-4RO is a 36-channel PC/104

pparatus, and embedded OEM.

and is also useful for slow DC inputs in noisy

disabled to improve the board’s typical

response time to 10µs when used with faster

DC inputs. To prevent erroneous input state

change detections and interrupts, Schmitt

triggers are used which provide a reliable

logic signal to the computer interface. The

to the kind of signals that can be switched.

Another useful feature of the board is a fused

+5V general purpose output at the connector.

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 and greatly frees up system

Each input circuit includes a jumper
