The 857 Series Jumpflex DIN-rail-mount relay and signal-conditioning modules provide a system approach to signal switching and conditioning in factory-automation and process-control applications requiring conversion, isolation, and transmission of many different signal types. Housed in a 6mm-wide package, the modules feature a push-in jumper system—in red, white, and blue colors—offering 2 to 10 poles.

Available in 12 versions, the signal conditioners support signal types such as current, voltage, Hart protocol, RTDs, and thermocouples. The pluggable relay modules are available in up to seven different versions, offering a variety of ac/dc coil voltages, and can switch loads up to 250 V and 5 A.
