The JUMO safetyM TB/TW is a freely programmable limiter / monitor. The universal measuring input is freely programmable for RTD temperature probes, thermocouples as well as current and voltage signals. TB/TWs are used to monitor thermal processes in the system for a set limit value.

If this value is exceeded, the installed relay switches the system to an operational safe status and the LED “K1” changes from green to red.
If the system reaches the “Good” range again, the “Reset” key must be unlocked manually with a respective tool for the TB. However, the TW automatically resets without external influence.

For an adjustable temperature, the DC 24V/20mA binary output can put out a pre-alarm prior to reaching the limit value additionally displayed by the LED “KV”.
TB/TW are installed on a top hat rail and wired via screw terminals with a cable cross section of 2.5mm max.

A setup program (and interface cable) is also available for advanced configuration.
