ICS Triplex T9110 Processor Module

Each processor module is galvanically isolated from external power supplies and data links so that any faults developed in the field cannot cause the module to fail. The module will continue to operate if a failure occurs in one of its dual redundant 24 Vdc power supplies. The module incorporates under- and over voltage protection for its internal power supplies, which show a 'power valid' signal to the modules own diagnostics microprocessor.

The modules regularly initiates internal diagnostic tests which, together with a watchdog circuit, monitor the processor performance. If the tests find a serious fault, the processor module will shut down. A single processor system will fail-safe. If a controller uses two or three processor modules and one processor module develops a fault, you can fit a new processor module while the controller is on-line without interrupting the operation of the other processors.

The new processor module automatically carries out self-education and synchronizes with the other processors.

Fault detection and fail-over in redundant processor configurations is automatic and has no impact on controller operation.
