Description
The Trusted TMR 24 / 48V dc Digital 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 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.
Features
40 Triple Modular Redundant (TMR) output channels per module.
Comprehensive, automatic diagnostics and self-test.
Automatic line monitoring per channel to detect open circuit and short circuit field wiring and load faults.
2500V dc optical isolation barrier.

Module can be hot-replaced on-line using dedicated Companion (adjacent) Slot or SmartSlot (one spare slot for many modules) configurations.
Front panel output status LEDs for each channel indicate output status and field wiring faults.
Front panel module status LEDs indicate module health and operational mode (Active, Standby, Educated)
TUV Certified IEC 61508 SIL 3
Outputs are powered in isolated groups of eight.
Each power group can be of a different voltage
Description
The Trusted TMR analogue input module interfaces to 40 single-ended field input devices. A wide input range and programmable thresholds allow the module to be used in most voltage or current configurations. Comprehensive diagnostic tests are performed on each input channel, including tests for out of range values and stuck at failures. Fault tolerance is achieved through Triple Modular Redundancy (TMR) within the same module for each of the 40 input channels.
The module can apply a digital filter to each input channel. Individual channels can be configured for high noise immunity (50Hz or 60Hz rejection), low noise immunity (fast response) or pass-through operation (no filtering).
Each input channel has four configurable state thresholds, which may be assigned to SOE reporting. A change of state triggers an SOE entry. The on-board sequence of events (SOE) reporting has a resolution of 1ms.
Each triplicated section of the module, referred to as a slice, conditions and measures each channel independently. Each slice is optically isolated up to 2500V dc. Each slice sends its data to a safety layer hardware voter that presents the information from all three slices to the Trusted TMR processor. When a fault is detected on a slice of the module, the Trusted TMR processor will flag the error, indicating the need to replace the module. The Trusted TMR processor will continue to use the information provided by the remaining two slices until a replacement module is available. Replacement modules can be located in a standby slot next to the module or in a designated SmartSlot with a temporary connection to the same Trusted termination assembly.
Modules may be placed in any I/O module slot in a Trusted processor chassis or expander chassis. Once the I/O module configuration is set, mechanical keying is available on all I/O modules to prevent inserting a module into an incorrect slot.
Configuration of the module is carried out using the Trusted Toolset running on an engineering workstation. Once configured and loaded into the Trusted controller, replacement modules are online educated by the TMR processor.
