If output controls a...
Resistance to ground must be...
0–10 Vdc device 500 Ohms minimum
0–20 mA device 500 Ohms maximum
NOTE The device must share the same ground as the expander.
Binary outputs
The outputs have a built-in relay and provide a dry contact so an external voltage source must be wired
to one of the two terminals.
Outputs set up as binary can be used to switch external devices and relays up to 1A, 30 Vac/Vdc.

NOTES
• Automated Logic® recommends use of an external current transducer between an RTD and the FIO
expander to improve accuracy and resolution.
• RTD inputs require either sensor calibration or an estimated offset correction for wiring resistance.
See Offset and Polarity values (page 22).
Output wiring
To size output wiring, consider the following:
• Total loop distance from the controller to the controlled device
NOTE Include the total distance of actual wire. For 2-conductor wires, this is twice the cable length.
• Acceptable voltage drop in the wire from the controller to the controlled device
• Resistance (Ohms) of the chosen wire gauge
• Maximum current (Amps) the controlled device requires to operate
