| Message: | Description
The Trusted TMR 24V dc digital output module interfaces to 40 field output devices. Outputs are arranged in five groups of eight outputs. All outputs in a group share a common power source and return. Fault tolerance is achieved through Triple Modular Redundancy (TMR) within the same module for each of the 40 output channels.
The module provides on-board sequence of events (SOE) reporting with a resolution of 1ms. The “event” is the actual sensing of the field device loop current.
