DPA/DMV

• Operation

General

The DPA/DMV allows you to set two independent trip points on a DC

millivolt signal. The alarm outputs are dual SPDT relay contacts.

Setup

The alarm relay coils operate according to each setpoint/deadband

configured via front panel multiturn potentiometers. Internal push

fit jumpers determine the alarm type (high or low acting) and coil

energisation (normally energised/de-energised).

Sensor power supply

A 24 V DC power supply output is available on terminal 1 for light loads

(it can supply currents up to 25 mA).
