Courtesy: WagoWago Corporation's 857-402 Jumpflex Universal Signal Conditioner (USC) supports 456 signal combinations with exclusive input voltage range and self-resetting fuse. Unlike competitive 12.5 mm devices, the 6 mm USC offers class-exclusive signal clipping and freely scalable voltage input range — ±60 mV to a segment-leading ±200 V. Current input range is ±0.3 mA to ±100 mA.

Constant signal precision

DIP switch configurable, the USC’s 456 signal combinations reportedly maintain precise, constant values — even after reconfiguration — via factory-calibrated, laser-capable resistors. 857-402 replaces the traditional screw potentiometer with an innovative, vibration-proof momentary rocker-style switch (MRS). The MRS has no end/stop point for signal settings/adjustments and provides scalability across entire measurement range.

Auto-reset fuse

857-402’s Auto-reset Fuse protects current input against overloads without impacting input value; fuse automatically resets after overload removal.

Signal clipping:

The USC’s signal clipping feature safeguards PLCs by switching between limiting and analog behavior. Example: if a transducer’s input exceeds 20 mA, the output signal is clipped at 20 mA. This ensures output will continue functioning properly, preventing errors.

857-402 is said to incorporate Jumpflex features, including: flexible color-coded, push-in jumpers, jumper slots at every connection point, one marking tag holder, ribbon cable interface adapter, 3 way 2.5kV isolation and Cage Clamp S termination technology. The USC’s operating temperature range is -25 C to +70 C.
