general information:
The TC125 temperature transducers convert signals of temperature resistance (Pt100 / Pt1000) or thermocouples (J, K, S) into standard signals (0/4..20 mA and 0/2..10 V).
Applications with signals from the Ex area or requirements of higher enviromental immunity require galvanic isolation. This applies espacially to grounded temperature sensors.
The TC125 therfore has a 3-way electrical isolation between input, output and auxiliary voltage. There are 8 preconfigured measuring ranges available for PT100, PT1000 and thermocouples which can be adjusted easily with trim potentiometers with regard to zero point and range. When using thermocouples, an internal temperature compensation - by measuring the terminal temperature - can be activate or deactivate.
With an intrinsically safe input (EX) the use in Ex-applications is possible.
- universal input for Pt100, Pt1000, thermocouple J / K / S
- thermocouples with temperature compensation that can be switched off
- available with intrinsically safe inputs, type of protection ia, zone 0/20
- pre-scalings that can be adjusted using trim potentiometers
- analog output 0(4) .. 20 mA and 0/(2)..10 V, simultaneously
- wide range AC / DC or 24 V DC supply
- optional auxiliary voltage supply via DIN rail bus
