T8480 Trusted TMR Analog Output Module – 40 Channel

The Trusted® TMR Analog Output Module interfaces to 40 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 Module for each of the 40 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.
The Module provides onboard Sequence of Events (SOE) reporting with a resolution of 1 ms. An output change of state triggers an SOE entry. Voltage and current measurements onboard the Module automatically determine the output states.

Features
• 40 Triple Modular Redundant (TMR) output channels per Module.
• Comprehensive, automatic diagnostics and self-test.
• Automatic line monitoring per point to detect open circuit and short circuit field wiring and load faults.
• 2500V impulse withstand opto/galvanic isolation barrier.
• Automatic overcurrent protection (per channel), no external fuses required.
• Onboard Sequence of Events (SOE) reporting with 1 ms resolution.
• Module can be hot-replaced online using dedicated Companion (adjacent) Slot or SmartSlot (one spare slot for many Modules) configurations.
• Front Panel output status light-emitting diodes (LEDs) for each point indicate output status and field wiring faults.
• Front Panel Module status LEDs indicate Module health and operational mode (Active, Standby, Educated).
• TϋV Certified for non-interfering applications, refer to the safety manual T8094.
• Outputs are powered in isolated groups of eight. Each such group is a Power Group (PG).

T8480 Trusted TMR Analog Output Module – 40 Channel

The TMR 4-20 mA Analog Output Module is a member of the Trusted range of input/output (I/O) Modules. All Trusted I/O Modules share common functionality and form. At the most general level, all I/O Modules interface to the Inter-Module Bus (IMB) which provides power and allows communication with the TMR Processor. In addition, all Modules have a field interface that is used to connect to Module-specific signals in the field. All Modules are Triple Modular Redundant (TMR).

All High Integrity I/O Modules are made up of four sections: Host Interface Unit (HIU), the Field Interface Unit (FIU), the Field Termination Unit (FTU), and the Front Panel Unit (or FPU).
Figure 2 shows a simplified block diagram of the Trusted 4-20 mA Analog Output Module.

The Field Termination Unit (FTU) is the section of the I/O Module that connects all three Field Interface Units (FIUs) to a single field interface. The
FTU provides the Group Fail Safe Switches and passive components necessary for signal conditioning, overvoltage protection, and EMI/RFI filtering. When installed in a Trusted Controller or Expander Chassis, the FTU field connector interconnects to the Field I/O Cable Assembly attached at the rear of the Chassis.
The SmartSlot link is passed from the HIU to the field connections via the FTU. These signals go directly to the field connector and maintain isolation from the I/O signals on the FTU. The SmartSlot link is the intelligent connection between Active and Standby Modules for coordination during Module replacement.

The Field Interface Unit (FIU) is the section of the Module that contains the specific circuits necessary to interface to the field I/O signals. Each Module has three FIUs, one per slice. For the TMR 4-20 mA Analog Output Module, the
FIU contains one slice of the output driver circuit, for each of the 40 field outputs.
The FIU receives isolated power from the HIU for logic. The FIU provides additional power conditioning for the operational voltages required by the
FIU circuitry. An isolated 6.25 Mbit/sec serial link connects each FIU to one of the HIU slices.
The FIU also measures a range of onboard “housekeeping” signals that assist in monitoring the performance and operating conditions of the Module.
These signals include power supply voltages, current consumption, onboard reference voltages, and board temperature.
