Triconex 3664 cpu module 7400159-030 3664

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. DDO modules are optimized for those safetycritical control programs where low cost is more important than maximum availability.
