DPA/TCX

•

Operation

General

The DPA/TCX allows you to set two independent trip points against

the temperature measured by a thermocouple. The units feature

automatic CJC to compensate for variations in ambient temperature.

They are specially built to suit a particular temperature range and

thermocouple type.

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).
