Trusted Fault Tolerant Control Systems

• 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

• 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 0.1Hz to 30 kHz.
• Sequence-of-events reporting with a 1ms resolution.
