Universal Transmitter UT125M, Transmitter for Electrical Signals

Universal Transmitter UT125M, Transmitter for Electrical Signals

• Transmitter for electrical signals
• Universal input for standard signals, Pt100, thermocouple, potentiometer, configuration via front-side DIP switch
• Analog output 4-20 mA
• With Pt100 sensors, monitoring of sensor break and short-circuit
• Wide-range power supply
• Housing width 12.5 mm
• Removable coded screw terminals
• Carrier rail mounting TS35 EN60715

The UT125 universal transmitter is designed for the affordable transformation of standard signals, temperatures and potentiometer statuses into a current signal of 4..20 mA. The universal configurability of the measuring inputs reduces the stock requirement for various applications. The measuring inputs and actual value output are not galvanically isolated. The housing width of only 12.5 mm enables space-saving installation in the switch cabinet.
