TMR Analogue Output

Module – 40 Channel

Introduction

The Trusted 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 on-board Sequence of Events (SOE) reporting with a resolution of 1ms. An output change of state triggers an SOE entry. Output states are automatically determined by voltage and current measurements on board the module.

Module T8480

1. Description

The TMR 4-20 mA Analogue Output module is a member of the TrustedTM range of Input/Output (I/O) modules. All Trusted 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).

I/O modules share common functionality and form. At the most general level,

All High Integrity I/O modules are made up of 4 sections: Host Interface Unit (HIU), the Field Interface Unit (FIU), the Field Termination Unit (FTU), and the Front Panel Unit (or FPU).

1.1. Output Field Termination Unit (OFTU)

The Output Field Termination Unit (OFTU) is the section of the I/O module that connects all three AO FIUs to a single field interface. The OFTU provides the Group Fail-safe switches and passive components necessary for signal conditioning, over-voltage protection, and EMI/RFI filtering. When installed in a Trusted Field I/O Cable Assembly attached at the rear of the chassis.

The OFTU receives regulated power and drive signals from the HIU and provides magnetically isolated power to each of the three AO FIU’s.

The SmartSlot link is passed from the HIU to the field connections via the OFTU. 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 co-ordination during module replacement.

Controller or Expander Chassis, the OFTU field connector interconnects to the

1.2. Analogue OUTPUT Field Interface Unit (AOFIU)

The Analogue Output Field Interface Unit (AOFIU) is the section of the module that contains the specific circuits necessary to interface to the field I/O signals. Each module has three AO FIUs, one per slice. For the TMR 24V dc Analogue Output Module, the AOFIU contains one slice of the output driver circuit, for each of the 40 field outputs.

The AOFIU receives isolated power from the OFTU for logic. The AOFIU provides additional power conditioning for the operational voltages required by the AOFIU circuitry. An isolated 6.25Mbit/sec serial link connects each AOFIU to one of the HIU slices.

The AOFIU also measures a range of on-board “house-keeping” signals that assist in monitoring the performance and operating conditions of the module. These signals include power supply voltages, current consumption, on-board reference voltages, and board temperature.

1.3. Host Interface Unit (HIU)

The HIU is the point of access to the Inter-Module Bus (IMB) for the module. It also provides power distribution and local programmable processing power. The HIU is the only section of the I/O module to directly connect to the IMB backplane. The HIU is common to most high integrity I/O types and has type dependent and product range common functions. Each HIU contains three independent slices, commonly referred to as A, B, and C.

All interconnections between the three slices incorporate isolation to prevent any fault interaction between the slices. Each slice is considered a Fault Containment Region (FCR), as a fault on one slice has no effect on the operation of the other slices.

The HIU provides the following services common to the modules in the family:

• High Speed Fault-Tolerant Communications with the TMR Processor via the IMB interface.

•

module data to IMB.

• Optically isolated serial data interface to the FIU slices.

•

power to HIU circuitry.

• Magnetically Isolated power to the HIU slices.

• Serial data interface to the FPU for module status LEDs.

• SmartSlot link between active and standby modules for co-

replacement.

• Digital Signal Processing to perform local data reduction and self-diagnostics.

• Local memory resources for storing module operation, configuration, and field I/O data.

• On-

temperature, and condensation.

1.4. Front Panel Unit (FPU)

The Front Panel Unit (FPU) contains the necessary connectors, switches, logic, and LED indicators for the front panel. For every module, the FPU contains the Slice Healthy, Active/Standby, the Educated indicators (LEDs), and the module removal switches. Additional bi-colour LEDs provide status indication for the individual I/O signals. Serial data interfaces connect the FPU to each of the HIU slices to control the LED status indicators and monitor the module removal switches.
