Product Short Description
Product Introduction
The GE 8851-LC-MT is a high-integrity, SIL2-certified safety logic controller within the GE PAC8000 series. It executes safety-critical control logic, provides dual-redundant fiber-optic Ethernet communication, and enables peer-to-peer data exchange between controllers. Designed for hazardous and high-reliability industrial environments, it serves as the core of safety instrumented systems (SIS) and integrates seamlessly with MTL8000 I/O modules.
