Contact and Demand Response Interfaces
Input and Demand Response Interface Wire Terminations
The Contact 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 0.2 mm
2
-4 mm
2
(24-12
AWG) wire. Each input supports wet or dry contact closures and includes a
related on board LED to indicate contact status.
Note:
Input terminals accept 3 - 24 VDC and support 610 m
(2,000 ft) of 1 mm
2
(18 AWG) wire (round trip wire to the device)
when using 24 VDC.
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 0.2 mm
2
-4 mm
2
(24-12 AWG) wire. Each
output includes a corresponding on board LED to indicate the normally open
status of the relay.
Installation
Install to DIN rail

3
1.
Ensure the section of DIN rail to be
used is mounted securely
according to the manufacturer’s
requirements. (DIN rail is provided
by others.)
2.
Hook the bottom of the device
under the lower DIN rail edge as
shown.
3.
Pivot the device up and depress
until the top clip seats completely
onto the DIN rail.
Terminate Wiring
Connect Auxiliary 24 VDC
1.
Strip 9-10 mm (3/8 in) of insulation from the end of each wire.
2.
Loosen the two 24 VDC screw terminals.
3.
Insert the negative voltage wire (black wire typical) into the terminal
labeled “-”, and insert the positive voltage wire (red wire typical) into
