TMR Isolated 4-20 mA
Analogue Input Module – 20 Channel
Introduction
The Trusted TM TMR Isolated 4-20 mA Analogue Input module interfaces to 20 current loop
transmitters. Each channel provides independent high voltage galvanic isolation from system ground,
as well as with respect to the other channels on the module. When used in conjunction with the T8833
Field Termination Assembly (FTA), the isolation barrier is powered from the current loop signal itself.
Comprehensive diagnostic tests are performed on each input channel. Fault tolerance is achieved
through a Triple Modular Redundant (TMR) architecture within the module for each of the 20 input
channels.
The module provides on-board Sequence of Events (SOE) reporting with a resolution of 1ms. A
change of state triggers an SOE entry. States are determined by voltage thresholds that can be
configured on a per channel basis.
Features
• 20 Triple Modular Redundant (TMR) isolated input channels per module.
• Comprehensive, automatic diagnostics and self-test.
• 2500Vdc optical/magnetic 2 stage galvanic isolation barrier.
• On-board Sequence of Events (SOE) reporting with 1ms resolution.
• Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or
SmartSlot (one spare slot for many modules) configurations.
• Front panel input status LEDs for each channel indicate input status and field wiring faults.
• Front panel module status LEDs indicate module health and operational mode (Active,
Standby, Educated)
• T 6 V Certified IEC 61508 SIL 3
