THE J TB/TW IS A FREELY PROGRAMMABLE TEMPERATURE LIMITING DEVICE. THE MEASUREMENT INPUT IS FREELY CONFIGURABLE FOR RESISTANCE THERMOMETERS AND THERMOCOUPLES, AS WELL AS FOR CURRENT AND VOLTAGE SIGNALS. TB/TWS MONITOR THERMAL PROCESSES IN SYSTEMS FOR A SET LIMIT VALUE. IF THIS IS EXCEEDED, THE BUILT-IN RELAY SWITCHES THE SYSTEM TO A SAFE OPERATIONAL STATE AND THE LED K1 LIGHTS UP. WHEN THE SYSTEM RETURNS TO THE O.K. REGION, THE RESET BUTTON (ON THE TB) HAS TO BE RELEASED MANUALLY USING AN APPROPRIATE TOOL. THE TW, ON THE OTHER HAND, IS RESET AUTOMATICALLY WITHOUT ANY EXTERNAL ACTION. THE 4.5V/20MA LOGIC OUTPUT PRODUCES A PRE-ALARM SIGNAL AT AN ADJUSTABLE TEMPERATURE BEFORE REACHING THE LIMIT VALUE, WHICH IS ADDITIONALLY INDICATED VIA THE LED K2. TB/TWS ARE MOUNTED ON DIN RAILS AND WIRED UP BY MEANS OF SCREW TERMINALS WITH 2.5MM² MAX. CONDUCTOR CROSS-SECTION. A PC SETUP PROGRAM IS AVAILABLE AS AN ACCESSORY, WHICH CAN BE USED TO SET AND STORE PROBE TYPE, RANGE, OUTPUT ACTION AND INHIBIT
