TMR 24Vdc Valve Monitor
Module - 40 Channel
Introduction
The Trusted TM TMR 24Vdc Valve Monitor module interfaces to 20 field devices. Each field device is
controlled through an output channel, and monitored through a separate input channel. 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 20 input and 20 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.
In addition to the normal control of the field device, this module includes features that allow for partial
stroke testing of valve devices while maintaining the field device availability in case of a demand. The
valve is monitored through limit switches, and the valve position, travel times, and test status are
reported.
Features
• 20 Triple Modular Redundant (TMR) control output points per module.
• 20 Triple Modular Redundant (TMR) feedback input points per module.
• Advanced valve diagnostics and active valve testing.
• Comprehensive, automatic diagnostics and self-test.
• Automatic line monitoring per point to detect open circuit, short circuit, field
wiring, and load faults.
• 2500Vdc optical isolation barrier.
• Automatic over-current protection (per channel), no fuses required.
• On-board Sequence of Events (SOE) reporting with 1 millisecond resolution.
• Module can be hot-replaced on-line using dedicated Standby (adjacent) Slot
or Smart-Slot (one spare slot for many modules) configurations.
• Front panel output status LEDs for each point indicate output status,
feedback status and field wiring faults.
• Front panel module status LEDs indicate module health and operational
mode (Active, Standby, Educated)
• T 5 V Certified Risk Class 6
