2. GENERAL DESCRIPTION

The XT130C, XT131C and XT130D, XT131D (DIN RAIL format) are dead band ON/OFF
controllers for temperature, humidity and pressure applications. They have been developed
and designed for applications in the industrial sector where the process variable must be
maintained constant within a fixed band. The analogue input type can be set by parameter
between the following, according to the model:

- PTC, NTC;

- PTC, NTC, Pt100, Thermocouple J, K, S;

- 4÷20mA, 0÷1V, 0÷10V.

Once the alarm signal is detected the buzzer, if present, can be disabled by pressing any key.
XT131C/ XT131D: the alarm relay status depends on the tbA parameter: with tbA=yES the
relay is disabled by pressing any key, with tbA=no the alarm relay remains enabled as long
as the alarm lasts. The display signal remains as long as the alarm condition remains.
