August 3, 2011 – WAGO's 857-402 JUMPFLEX Universal Signal Conditioner (USC) supports 456 signal combinations with exclusive input voltage range and self-resetting fuse. The 6mm USC offers signal clipping and freely scalable voltage input range from ±60mV to ±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 a 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.
Ex: if a transducer’s input exceeds 20mA, the output signal is clipped at 20mA. This ensures output will continue functioning properly, preventing errors. 857-402 features include: flexible color-coded, push-in jumpers, jumper slots at every connection point, a single marking tag holder, ribbon cable interface adapter, 3 way 2.5kV isolation and CAGE CLAMP termination technology. The USC’s operating temperature range is -25°C to +70°C.
