Description
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.The SafetyNet Controller has a number of LED’s that indicate the status and mode of operation of the Controller.
Applications
Oil & Gas: Signal conditioning for transmitters in explosive atmospheres.
Chemical/Petrochemical: Safe signal transmission from hazardous zones.
Power Plants: Isolation of 4-20mA loops in critical processes.
