Gestra TRS5-52

Description

The temperature switch TRS 5-52 is used in conjunction with temperature sensors TRG 5-6.. as max. -min. limit switch, for instance in steam boilers and (pressurised) hot-water plants. The temperature switch detects and indicates a MIN and a MAX temperature. The temperature switch TRS 5-52 is designed for use in conjunction with temperature sensors TRG 5-63, TRG 5-64, TRG 5-65, TRG 5-66, TRG 5-67 and TRG 5-68. Function A platinum resistance thermometer Pt 100 to EN 60751 is used as temperature sensor for the temperature switch TRS 5-52. A three-wire configuration is used for the electrical connection.

The temperature switch processes the temperature-dependent changes in resistance of the temperature sensor and during normal operation the seven-segment LED display shows the actual value. The switchpoints for MIN and MAX temperature can be variably adjusted within the measuring range. When the MIN or MAX temperature is reached, the MIN or MAX output contact is switched over and MIN or MAX LED is illuminated. Any error or malfunction that occurs in the temperature sensor, the electrical connection or the settings is indicated by the seven-segment LED display and will trigger a MIN and MAX alarm. If an error occurs in the temperature switch TRS 5-52, only the MIN and MAX alarm is raised and the system is restarted. Parameter settings can be changed or a MIN/MAX alarm be simulated by operating the rotary button. For external temperature indication the equipment is optionally available with an actual-value output 4 - 20 mA.
