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).
Sensorpowersupply
A 4 V DC power supply output is available on terminal 1 for light loads
(it can supply currents up to 5 mA).
