The Trusted TMR T8480 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.Automatic line-monitoring of the field device is provided. This feature enables the Module to detect both open and short circuit failures in field wiring and load devices.

The new T8480 is available in stock and has a complete quality test. There is only one left and the price is favorable. If you are interested in it, please feel free to contact tony@swanautomation.com.
