Features:
- Interface Between Speed Sensors and ICS Triplex Safety Control System Backplane
- Combines Capability of Speed Signal Processing with Triplicated Redundancy Support
- Operates in Conjunction with the T Series and Standard ICS Triplex Safety Monitors
The T8442C operates as the Speed Monitor Module in an ICS Triplex safety rack, providing reliable speed monitoring functionality to all modules within the system. It continuously processes incoming speed sensor signals and distributes processed data through the rack backplane to support steady state operation of all safety monitors and modules. Seamless signal processing is standard with the T8442C, however using the inherent Triplicated Architecture will allow seamless operation in the event of a single processing channel failure. The T8442C has incorporated triplicated voting capability within the ICS Triplex safety rack.
The T8442C provides essential speed monitoring functions common to the entire rack, and is a critical component of the safety path, directly affecting the proper, normal operation of the overall safety system. One T8442C module is required per speed monitoring point depending on the desired safety integrity level. The T8442C occupies a standard slot in the rack and is located in the designated monitor positions.
For Triplicated Safety applications, the T8442C utilizes its three independent processing channels operating in parallel. In addition to standard signal processing operation, the triplicated configuration also performs automatic voting. The T8442C triplicated architecture executes fault detection using the internal circuitry specified in the module specifications. Using this method, the triplicated system continually monitors the health of all three channels. If the system detects that one processing channel is no longer providing valid output (outside configured tolerance levels), it will automatically isolate the faulty channel and place an event in the System Event List.
The T8442C ICS Triplex Speed Monitor Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
