ICS Trusted Triple Modular Redundant (TMR) Systems
Description
Trusted System:
The Trusted® solution features a Triple Modular Redundant (TMR) controller. It is designed to provide maximum safety and system availability. Trusted uses control to minimize system trips and provides high availability, fault tolerance and fail-safe features as part of its intrinsic, safety-related functionality. The architecture features:
Trusted controller is a highly compact solution. It can hold up to 240 TMR I/O channels in a single Trusted controller chassis, including a spare processor, dual ethernet and multiple serial communications capability.
Trusted expander can connect up to 28 I/O expander chassis, totalling up to 128 I/O modules per system. The expander chassis may be located up to 5km away and are connected to the controller processor chassis by triplicated fiber optic links.
Trusted I/O modules are designed to meet the SIL 3 requirement, for both analog and digital signals. All models have full “stuck on / stuck off” signal testing and configurable line monitoring. Trusted offers a wide range of standard I/O module types including 120V AC and 125V DC inputs and outputs.
Modular power system can be powered directly from a single or dual conditioned 24V DC supply, or from AC power sources and redundant power feeds.

Trusted supports a number of I/O modules that meet special process control requirements
The Valve Test module:
Partial stroke testing of critical valves is a crucial feature that meets the latest process safety standards. The Trusted system integrates automatic valve testing inside a TMR, TÜV approved SIL3 architecture, providing maximum safety and availability. With this package, you are able to periodically test the valve and actuator subsystem without shutting down your process.
The Zone Interface module:
The Trusted Zone Interface helps reduce the complexity of a Fire & Gas system by integrating all functions into a single module. It can be used in combination with any other Trusted hardware. The 40-channel Zone Interface module provides:
• Fault tolerant monitoring of any 4-20mA gas detector, in addition to any low-voltage digital signal, with line monitoring. These include flame, smoke or heat detectors and manual alarm call points.
• Outputs for the control and alarm of hazards as well as the calibration of detectors.
The Speed Monitor module:
Trusted offers a high integrity solution for the protection of gas/steam turbine acceleration and over-speed prevention. The module provides:
• Autonomous over-speed protection for up to three rotating machines. Each over-speed trip has three independent, fault tolerant speed inputs and a fault tolerant digital output.
• Speed inputs have a wide, dynamic range of 0.1 Hz to 30 kHz.
• Sequence-of-events reporting with a 1 ms resolution.
