Invensys TRICONEX 3664 3674 Dual Digital Output Module CPU Module
3664 3674 Dual Digital Output Module CPU Module Function
The dual digital output (DDO) modules receive output signals from the main processors along a single parallel or series path, and applies a 2-out-of-3 voting process individually to each switch. The switches produce one output signal which is then passed to the field termination. While the quadruplicated output circuitry on TMR modules provides multiple redundancy for all critical signal paths, dual circuitry provides just enough redundancy to ensure safe operation. The dual module is optimized for those safety-critical control programs where low cost is more important than maximum availability.
The dual digital output modules have a voltage-loopback circuit which verifies the operation of each output switch independently of the presence of a load and determines whether latent faults exist. Failure of the detected field voltage to match the commanded state of the output point activates the LOAD/FUSE alarm indicator.
