Product Details
General
The 8851-LC-MT SafetyNet Controller stores and runs the SafetyNet application program which is downloaded from the Workbench. It manages a number of communication paths: with the IO Modules mounted on the local node via the internal Railbus; with other entities on the Ethernet LAN (other MOST nodes, PCs running the Workbench programming tools, HMI,historian packages and asset management tools) and with remote mounted serial devices. The SafetyNet Controller also manages the implementation of the redundancy strategy either as master or standby.
Certification
The 8851-LC-MT GE SafetyNet Controller is certified for SIL 2 safety applications, operating in a 1oo1D simplex mode with extensive internal diagnostics. It integrates with the 8811-IO-DC Digital Input/Output Module and 8810-HI-TX Analog Input Module with HART* for comprehensive safety management. Mounted on the dedicated Carrier 8751-CA-NS, the controller ensures reliable operation in safety-critical environments.
Redundant Controllers
SafetyNet Controllers can be configured in a master-standby redundant setup to enhance safety function availability, though redundancy is not mandatory for safety compliance. To implement redundancy, simply insert the new controller into the available slot on the Controller Carrier. The SafetyNet system will automatically upload the necessary application to the new controller and activate redundancy algorithms.
