Input and Demand Response Interface Wire Terminations
The Input and Demand Response Interfaces provide four sets of terminals
(“In” and “V out”) for connection to a momentary (Input Interface only) or
maintained contact input. Terminals accept 24-12 AWG (0.2 mm

)
wire.
Each input supports wet or dry contact closures and includes a related
onboard LED to indicate contact status.
Output Interface Wire Terminations
The Contact Output Interface provides four sets of terminals (normally open
“N.O.”, normally closed “N.C.”, and common “COM”) for connection of
output relays. Terminals accept 24-12 AWG (0.2 mm

) wire.
Each output includes a corresponding onboard LED to indicate the normally
open status of the relay.
Installation
Install to DIN rail
Note: Input terminals accept 3 - 24 VDC, and support 2,000
feet (610 m) of 18 AWG (1 mm
2
) wire (round trip wire
to the device) when using 24 VDC.
Note: Each output is rated for 2A at 30 VAC or 30 VDC.
