Description
- PC configuration interface
- For Pt100, Pt200, Pt500 and Pt1000 sensors, as well as resistors up to 4.5 kOhm
- 2-, 3-, and 4-wire connection technology.
- Detect calibrated measurement range switching
- Detect wire break/sensor short circuit
- Measurement range underflow/overflow
- Integrate a switchable clipping function to limit the standard analog signal to the upper range values
- Safe 3-way isolation with 2.5 kV test voltage per EN 61140
The WAGO 857 series temperature signal conditioner features a DIP switch and software/app interface configuration, supporting one analog input for various RTD sensors (Pt100, Pt200, Pt500, Pt1000) and resistors (0-1k?, 0-4.5k?) with switchable 2-wire, 3-wire, or 4-wire connections. It also includes one analog output with multiple signal options (0-10mA, 2-10mA, 0-20mA, 4-20mA, 0-5Vdc, 1-5Vdc, 0-10Vdc, 2-10Vdc). The device operates on a supply voltage of 16.8-26.4Vdc (24Vdc nominal), features Push-in CAGE CLAMP spring connections, mounts on a DIN-35 rail with a 6mm width, and is rated IP20 for ambient temperatures ranging from -25°C to +70°C, equivalent to model 857801.
