3BSE023607R1 ABB TY801K01 ShuntStick

Product Description

The TY801K01 (3BSE023607R1) is a precision shunt resistor assembly specifically engineered for the ABB S800 I/O system. This dual-element "shunt stick" provides a $125 + 125\ \Omega$ resistive interface, primarily used to convert 4-20 mA current signals into voltage inputs compatible with high-density analog modules. Designed for seamless integration into specific Module Termination Units (MTUs), the TY801K01 ensures signal stability and high-accuracy data acquisition for critical process control loops.
