The M3-3TT5B.040X.W70BD is a tricolour 5-digit meter for temperature measuring via Thermocouples and a visual limit value monitoring via the dis- play. The configuration happens via three front keys or via an optional PC-software. Optional one analog output, interfaces RS232/RS485 and two switching points are available. Select- able software functions and a direct limit value adjustment in operating mode complete the modern device concept.
