• Operation

General

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

milliamp signal (typically 4-20 mA). The alarm outputs are dual SPDT

relay contacts.

Setup

The alarm relay coils operate accoridng 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).
