Outputs
The MPC Open XP and expanders have universal outputs that you can use as binary outputs or analog outputs.
The outputs support:
•
driving external 24 Vdc relays
•
0-10 Vdc devices
•
0-20 mA devices
WARNING
Binary outputs are powered, 24 Vdc channels. Dry contact binary outputs are not supported in
this product line. Do NOT apply 24 Vac to these universal outputs.
If output controls a...
Resistance to ground must be...
0–10 Vdc device
500 Ohms minimum
0–20 mA device
800 Ohms maximum
NOTES
•
The device must share the same ground as the controller.
•
The total output current from all outputs and the
Aux Power Out
connection must not exceed:
500 mA at 115°F
300 mA at 140°F
For temperatures above 115°F, use the following equation to calculate the total current at 8 mA per degree:
