NOTES:
1. Terminal blocks can accommodate 14-22 AWG solid
wiring.
2. ±Io/±Vo labeling is present only when the unit is equipped
with the Analog Output (-AO) option.
3. Your input power requirement (AC or DC / ACC or DCC).
KEY:
AC or DC = Power Input
ACC or DCC = Power Input
CM = Relay Common
GND = Ground
Io = Current Output
MR = Manual Reset
NO = Normally Open
NC = Normally Closed
Sink = Current Sink
Source = Current Source
SPDT = Single-Pole/Double-Throw
Vo = Voltage Output
