KEY:
AC/DC = Power Input
ACC/DCC = Power Input
CM = Relay Common
COM = Analog Common
DPDT = Double-Pole/Double-Throw
GND = Ground
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) will depend upon your unit’s power need.
