JUMO 506486 Temperaturbegrenzer/ -wächter, Pt

The programmable temperature limiter / monitor according to DIN EN 14597 for DIN-rail mounting. Voltage supply is AC/DC 20 to 30 V, 48 to 63 Hz 5 VA. The universal measuring input is configurable for RTD temperature probe, thermocouples and current/voltage signals. TB/TW 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. If the system returns to the good range, the Reset button on the TB must be manually unlocked using an appropriate tool. External unlocking is also possible. The TW, on the other hand, resets itself automatically without external influence. A binary output DC 24 V / 20 mA can, at an adjustable temperature, issue a pre-alarm signal before reaching the limit value, which is additionally indicated by LED KV. The TB/TW with a width of 22.5 mm is mounted on top-hat rails and wired via screw terminals with a maximum wire cross-section of 2.5 mm². It also has cULus approval.
