Triconex 3301 Digital Input Module
TRICONEX Triple redundant fault-tolerant control system is introduced:Invensys TRICONEX system, completely follow IEC61508/61511 standard, adopt the most advanced TMR microprocessor hardware technology, mature and reliable TRISTATION 1131 triple redundant fault-tolerant control system of the software.
System of high reliability and high efficiency, is widely used in petrochemical, oil refining, petroleum, chemical, electric power, rail transportation, aerospace, nuclear industry and other industries, the device safety interlock system ESD, steam turbine, gas turbine control, compression pant of vibration control, offshore oil platform, internal heat monitoring protection (head), there are a wide range of aspects such as performance.
The Tricon system can be rackmounted or panel-mounted in an industry-standard NEMA enclosure as described on the next page. Cabinets can optionally be equipped with base and casters. Multiple cabinets can be bolted together on the sides, but sufficient clearance must be allowed to fully open their front and rear doors.
