JUMPFLEX signal conditioner; temperature; loop-powered RTD; configurable.
The WAGO 857 series loop-powered temperature signal conditioner features a DIP switch and supports various RTD inputs (Pt100, Pt200, Pt500, Pt1000) and resistors (0-1k?, 0-4.5k?) with switchable 2-wire, 3-wire, or 4-wire configurations. It provides a single analog output (4-20mA) and operates on a supply voltage range of 8-30Vdc (nominally 12Vdc or 24Vdc). The device includes Push-in CAGE CLAMP spring connections, is designed for DIN-35 rail mounting with a 6mm width, and is rated for ambient temperatures between -25°C and +70°C, with an IP20 protection rating. It is equivalent to model 857815.
