JUMO 506382 Temperaturbegrenzer/ -wächter, Pt

Programmable temperature limiter/monitor according to DIN EN 14597 for DIN-rail mounting. Voltage supply AC 110 bis 240 V,-10/+15 %, 48 bis 63 Hz, 5 VA. The JUMO TB/TW is a programmable limiter/monitor. The universal measuring input is configurable for RTD temperature probes, thermocouples, and current/voltage signals. TB/TWs are used to monitor thermal processes in the plant for a set limit value. If this value is exceeded, the installed relay switches the plant to a safe operating state and the LED K1 switches from green to red. In the case of the temperature limiter (TB), when the plant returns to the valid range the Reset key must be pushed with an appropriate tool to unlock it manually. External unlocking is also possible. The temperature monitor (TW), on the other hand, automatically resets without external influence. The binary output 24&nbsp,V/20&nbsp,mA produces a pre-alarm signal at an adjustable temperature before reaching the limit value. The pre-alarm is additionally indicated via the LED KV. The TB/TW with overall width 22.5&nbsp,mm is mounted on DIN rails and wired via screw terminals with a conductor cross section of max. 2.5&nbsp,mm². In addition, it also has cULus approval.
