Trusted TMR 120 Vac Digital Output Module – 16
Channel
Product Overview
The Trusted® 120 Vac Digital Output Module interfaces to 16 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 System Side and Quad Element redundancy for each of the 16 output channel circuits.
The Module provides on-board Sequence of Events (SOE) reporting with a resolution of 1 ms. An
output change of state triggers an SOE entry. Output states are automatically determined by
multiple voltage and current measurements for each of the 16 channels of the Module.
Features:
• Triplicated TMR system architecture, with fault tolerant output switching.
• 16 Output Channels: 120 Vac, 0.5 A per channel, field powered as two groups of 8.
• Comprehensive, automatic diagnostics and self-test.
• Short circuit monitoring per channel when energized (requires regular proof testing for
safety related normally de-energized outputs, e.g. F&G).
• Open circuit monitoring when energized or de-energized
• 2500 V impulse withstand opto/galvanic isolation barrier.
• Automatic channel over-current protection, no fuses required.
• On-board Sequence of Events (SOE) reporting with 1 ms resolution.
• Module can be hot-replaced on-line using dedicated 'Companion Slot' (adjacent slot) or
SmartSlot (one spare slot for many Modules) configurations.
• Front Panel output status Light Emitting Diodes (LEDs) for each channel indicate output
status and field wiring faults.
