Power Connections
Power connections are made to two terminals.

Signal Connections
Signal connections are made to a group of three
terminals. Use the labeling appropriate to the desired
input.
Additional setup and programming is performed using
the SuperNova software or through the front panel
buttons.
Thermocouple
Connect the thermocouple with the positive side to
plus and the negative side (typically red) to minus.
RTD
For a three-wire RTD, connect the single lead to
terminal A. Connect the identical leads to terminal B
and B’ to compensate for lead resistance (typically
identical colors).
Voltage
Connect the positive and negative of the voltage
source device to the positive and negative terminals.
Current
To accept a 4-20 mA input, connect the positive
terminal to + and the negative, return, or common
wire to -. In addition, connect an external 250
Ω
resistor across the + and – terminals.

Relay Connections
Each controller has 3 or 4 relay outputs, one or two
control relays and 2 alarm relays.
If the controller has a main control relay, OUT1 will be
labelled as a relay (RLY) output. Control output 2 is
always OUT2, and is always a relay (RLY) output.
The alarm relay connections are made to terminals
SUB1 and SUB2.
Each relay is a form A relay with a normally open
(NO) and common (COM) contact. OUT1 and OUT2
are isolated. SUB1 and SUB2 alarm relays share a
common COM contact.
