This device may have a programmable communication output. The RS-232 and
RS-485 Output Connection are shown below.

This device may also have an excitation
output.
Excitation is not available if
communication option is installed.
If the Dual Display model has a Low
Voltage power supply option, then
excitation is not available.
This device has snubber circuits designed to
protect the contacts of the mechanical relays
when it switches to inductive loads (i.e.
solenoids, relays). These snubbers are
internally connected between the Common (C)
and Normally Open (NO) relay contacts of
Output 1 and Output 2.
If you have an inductive load connected
between Common (C) and Normally
Closed (NC) contacts of the
mechanical relays and you want to
protect them from the rush current
during the switching period, you have
to connect an external snubber circuit
between Common (C) and Normally
Closed (NC) contacts as indicated in
Figure 2.10.
