Jumo Temperature Limiter SafetyM TB/TW , Guard According To DIN EN 14597

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 for a set limit value. If this limit value is exceeded, the built-in relay switches the plant to an operationally safe state and the LED “K1” changes from green to red. If the system returns to the OK range, the “Reset” button on the TB must be manually unlocked with an appropriate tool. The TW, on the other hand, resets itself automatically without external intervention. A binary output DC 24V/20mA can emit a pre-alarm signal at an adjustable temperature before the limit value is reached, which is additionally indicated via LED “KV”. TB/TW are mounted on top-hat rails and wired via screw terminals with a cable cross-section of max. 2.5mm2. A setup program is available for configuration.
