T8480C Analogue Output Module P8480

The Trusted TMR Analogue Output module interfaces to 40 field devices. Triplicated diagnostic tests are performed throughout the module including measurements for current, and voltage on each portion of the voted output channel. Tests are also performed for stuck on and stuck off failures. Fault tolerance is achieved through a Triple Modular Redundant (TMR) architecture within the module for each of the 40 output channels.
