Panel-mount temperature transmitter TC125

Pt100Pt1000resistance

The TC125 temperature transmitters convert signal 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. PT100, Pt1000 and thermocouples have 8 preconfigured measuring ranges available. With trim potentiometers in the front, zero point and range can be adjusted easyly. 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. ●Thermocouples with temperature compensation that can be switched off ●Development conforms to EN 61508 ●Available with intrinsically safe inputs, type of protection ia, Zone 0/20 ●24 pre-scalings that can be adjusted using trimmer 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
