857-402 JUMPFLEX Universal Signal Conditioner

The 857-402 JUMPFLEX® Universal Signal Conditioner (USC) supports 456 signal combinations with exclusive input voltage range and self-resetting fuse. Unlike competitive 12.5mm devices, the 6mm USC offers class-exclusive signal clipping and freely scalable voltage input range—±60mV to a segment-leading ±200V. Current input range is ±0.3 mA to ±100mA.
DIP switch configurable, the USC’s 456 signal combinations 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.
857-402’s Auto-reset Fuse protects current input against overloads without impacting input value; fuse automatically resets after overload removal. The USC’s signal clipping feature safeguards PLCs by switching between limiting and analog behavior.
