wall mounted antenna to be
placed in a location which can
easily transmit and receive
wireless signals.
Power Relay
Module
mounted and installed in a high voltage rated
electrical box. Schedulable relays for switching On/Off
electrical loads.

System Components
The power relay module can either be mounted inside an electrical sub panel with circuit breakers or
in its own dedicated electrical box. Mounting tabs are provided on each end of the module. The
module should be securely fastened to the inside of the electrical box using the mounting tabs and
screws. Each relay on the module has a green light to indicate when it is active. There is also a
single green status light located next to the low voltage terminal block indicating the status of
communications with the wireless module.
Connect the 277VAC power wires between
“L” and “N”. The input power is reduced to
24VAC to provide isolated power to the relay
control circuit and the wireless control
module. A built-in auto-reset fuse limits
current to 0.3 Amps to provide short circuit
protection for the control interface.

1 Power Options
There are (5) sets of relay connections.
Each connection is independent and can
operate at different voltages and currents.
The dry contacts are rated to
120VAC@15AMPS and 240/277VAC
@10AMPS. Each relay operates as a
mechanical on/off switch and is intended to
control the LINE side of the circuit.
The module is powered by 277VAC.

WARNING
!
DO NOT USE THE 24VAC OUTPUT
TO POWER ANY OTHER DEVICES.
There are (8) screw terminals on the relay
module. The terminals labeled R, C, and D
are used to connect the relay module to the
wireless control module. 18 to 24 gauge
wire is recommended for this connection.
Terminal functions are as followed: D –
Data/Communication, R – 24VAC supply
power, C – Common Wire (Diagram 2).
