The GE IS220YSILS1B is a core safety protection I/O pack module designed for GE’s Mark VIe and Mark VIeS control systems. Purpose‑built for safety‑critical signal interfacing, this module captures and conditions discrete safety inputs — such as emergency stop (E‑stop) switches, limit interlocks, pressure or temperature trip signals — and transmits them reliably to the safety logic and controller. Its design meets Safety Integrity Level (SIL) 2 benchmarks and is internationally certified for use in regulated industrial environments such as power plants, petrochemical facilities, and turbine systems.
