4-20 mA Output Connections
Connections for the 4-20 mA retransmit output are
made to the connector terminals labeled mA OUT.
The 4-20 mA output is an active output, powered by
an internal 12 VDC power supply.

Connections
Digital Input Connections
Connections to the optional digital inputs are made to
the connector terminals labeled DI1, DI2, and COM.
Closing DI1 or DI2 to COM will activate that digital
input. Both digital inputs share a single common.

Remote SV Input Connections
Connections to the remote set value input are made
to the connector terminals labeled REM+ and REM-.
This input accepts a 1-5 VDC input. Connect the
positive and negative of the voltage source device to
the positive and negative terminals.
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.
