Invensys Triconex 3503E TMR Digital Input Module

TMR Digital Input Modules

On TMR Digital Input Modules, all critical signal paths are 100 percent triplicated to guarantee safety and maximum availability. Each channel conditions signals independently and provides isolation between the field and the Tricon controller. 

3503E has a self-test feature which verifies the ability of the Tricon controller to detect transitions from a normally energized circuit to the Off state. Because most safety systems use a de-energize-to-trip setting, the ability to detect the Off state is an important feature. To test for stuck-On inputs, a switch within the input circuitry is closed to allow a zero input (Off) to be read by the optical isolation circuitry. The last data reading is frozen in the I/O Processor while the test is running.
