- No additional supply voltage required
- Safe 2-way isolation with 2.5kV test voltage per EN 61140
The WAGO 857 series single-channel passive isolator features a passive supplementary voltage and includes one analog input (0-20mA / 4-20mA) and one analog output (0-20mA / 4-20mA). It utilizes Push-in CAGE CLAMP spring connections and is designed for DIN-35 rail mounting with a width of 6mm. The device is rated for an ambient temperature range of -25°C to +70°C and has an IP20 protection rating, equivalent to model 857451.
