One compact transmitter can simplify cabinet planning when different input signals need the same output format. This universal transmitter converts standard signals, temperatures and potentiometer positions into a 4..20 mA current signal for further processing in control or monitoring systems.
The measuring input is configured via front-side DIP switches for 0/2..10 V, 0/4..20 mA, Pt100, thermocouples Type J, K and S, or potentiometers with a rated value from 500 Ω..20 kΩ. Linearized temperature ranges and an analog output with max. 400 Ω burden support straightforward signal conversion in cabinet applications.
With a housing width of only 12.5 mm, the UT125 helps save space on the TS35 carrier rail. Versions are available with 24 V DC supply, 24 V DC with carrier rail bus connection, or wide-range supply from 20..125 V DC and 20..250 V AC. For Pt100 inputs, sensor break and short-circuit monitoring drive the analog output to approx. 0 mA.
DIP switches select current, voltage, potentiometer, Pt100 or thermocouple input. Simultaneous voltage and current input adds the related input signals.
The device actuates a 4..20 mA actual value output according to the selected measuring range.
Pt100 and thermocouple measuring ranges are linearized for conversion into the analog output signal.
The resistance input supports 3-wire potentiometers with a rated value from 500 Ω..20 kΩ and uses an internal reference voltage of approx. 1.5 V.
Versions are available for 24 V DC, 24 V DC with carrier rail bus connection, or wide-range supply of 20..125 V DC and 20..250 V AC.
The UT125LP version allows the power supply of multiple devices to be concentrated in the TS35 carrier rail bus system.
The housing uses removable coded screw terminals as standard. Push-in spring terminals are available as an option.
