The JUMO TB/TW is a freely programmable limiter / monitor. The universal measuring input is freely configurable for resistance thermometers, thermocouples as well as current and voltage signals. TB/TW monitor thermal processes in plants to a set limit. If this is exceeded, the built-in relay switches the system to an operationally safe state and the LED K1 switches from green to red. If the system returns to the good range, the Reset button must be unlocked manually with a suitable tool for the TB. The TW, on the other hand, automatically restores itself without any external influence. A binary output DC 24V/20mA can output a pre-alarm signal at an adjustable temperature before reaching the limit value, which is also displayed via LED KV. TB/TW are mounted on top of hat rails and wired via screw terminals with a cable cross-section of max. 2.5mm2. A setup program is available for configuration.This text is machine translated.
