Wiring Diagram
The wiring diagram provides required wiring information.
12 VAC/DC @ 250 mA must be supplied to the unit’s
“power input.” Connect unit as indicated. If the unit is
powered by a step down transformer, then 24, 115 or 230
VAC must be connected to the transformer primary and
the secondary connected to the power input of the
controller/indicator.
Power and thermocouple wire should not be placed in
the same conduit or wiring trough. However, wires from
several thermocouples may be in the same conduit
or wiring trough. If shielded thermocouples are used,
the shields should be insulated electrically from the
thermocouple wires and terminated to earth ground.
Ungrounded thermocouples are required when
multiple controllers/indicators are used or if the
transformer is grounded.
Wiring Diagram―Different Power Requirement
For long thermocouple runs, the proper thermocouple
extension wire must be used, and the proper polarity
must be maintained. If these precautions are not
observed, the unit may not meet specifications.

The Diagram above illustrates how to wire the relays for
the different power requirements.
The relay must have an external power source for you to
be able to control your device.
