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).
