JUMPFLEX signal conditioner; isolation amplifier; fixed for current signals - in: 0(4)
20 mA, out: 0(4)
20 mA.
The WAGO 857 series single-channel isolation amplifier features one analog input and one analog output, both supporting 0-20mA and 4-20mA signals. It operates on a supply voltage range of 16.8-26.4Vdc (nominally 24Vdc) and utilizes Push-in CAGE CLAMP spring connections. Designed for DIN-35 rail mounting with a 6mm width, it is rated IP20 and can function in ambient temperatures ranging from -25°C to +70°C. This model is equivalent to the 857411.
