Temperature controllers
Product description
Controller in DIN rail housing; current input 4-20mA , with 2 relays. 3-state control.
Special version can be ordered where second relay is used for delay or mixing function.
Possible control manners:
- ON/OFF control with alarm threshold
- temperature meter with 2 thresholds
- 3-state control (relative or absolute thresholds)
- ON/OFF control with alarm threshold
- temperature meter with 2 thresholds
- 3-state control (relative or absolute thresholds)
- ON/OFF control and set cyclical mixing function (P3 output)
- ON/OFF control and delayed output
RET-62 measures temperature with a PT-100 sensor attached with a triple conductor.
The controller software compares measured temperature with set values. Results of this comparison are control signals switching relays according to the controller configuration settings.
When relays are on, it is signaled with light-emitting diodes on the front panel. Values of temperature and other parameters are being shown on a three-digit display.

RET-62 is designed to control temperature in rooms, cooling chambers, dryers, bakeries, pressure plates etc., or to signal set temperature thresholds overrun.
This controller cannot be used as a protective controller for other devices.
