The WAGO 857 series single-channel bipolar isolation amplifier features a DIP switch and supports a variety of analog input and output ranges, including current (-10 to +10mA, -20 to +20mA, 0-10mA, 2-10mA, 0-20mA, 4-20mA) and voltage (-5 to +5Vdc, -10 to +10Vdc, 0-5Vdc, 1-5Vdc, 0-10Vdc, 2-10Vdc). It operates on a supply voltage of 16.8-26.4Vdc (24Vdc nominal) and features Push-in CAGE CLAMP spring connections for easy installation on a DIN-35 rail with a compact 6mm width. The device is rated for an ambient temperature range of -25°C to +70°C and has an IP20 protection rating, equivalent to model 857409.
