Description
The WAGO 857 series temperature signal conditioner features a DIP switch and includes one analog input compatible with various RTD sensors (Pt100, Pt200, Pt500, Pt1000) and resistors (0-1k?, 0-4.5k?) with switchable 2-wire, 3-wire, or 4-wire configurations. It also has one analog output supporting multiple current (0-10mA, 2-10mA, 0-20mA, 4-20mA) and voltage (0-5Vdc, 1-5Vdc, 0-10Vdc, 2-10Vdc) ranges. The device operates on a supply voltage of 16.8-26.4Vdc (nominal 24Vdc) and features Push-in CAGE CLAMP spring connections for easy installation on a DIN-35 rail (6mm width). It is rated for an ambient temperature range of -25°C to +70°C and has an IP20 protection rating, equivalent to model 857800.
