GE 8851-LC-MT SafetyNet SIL 2 Certified Safety Controller

The GE 8851-LC-MT SafetyNet SIL 2 Certified Safety Controller is a safety controller certified to IEC 61508 SIL 2, confirmed in GE Fanuc's own SafetyNet system documentation. It runs safety-related logic — emergency stop, interlock and fault alarm functions — to protect personnel and equipment in critical industrial processes. Operating as the control node of a SafetyNet safety network, it polls and arbitrates safety I/O and provides status indication through front-panel LEDs, with a 9-pin D-sub serial interface for configuration.
