TRICONEX Trident Controller

To support large-scale distributed I/O, Trident introduced the I/O extender module kits. These kits are used to transfer I/O messages between different I/O columns and provide logical power terminals for each I/O column. In a typical system, a maximum of 8 baseboards are allowed to be connected end-to-end in a single I/O column. When exceeding this limit, I/O extender modules and I/O bus cables need to be used for expansion. The maximum allowable length of the I/O bus is 650 feet (200 meters), and termination kits must be added at both ends of the bus if it exceeds 20 feet.

The baseboards are connected through Interconnect Assemblies, which consist of PCBs with DIN-C 96 pin connectors for carrying I/O messages and logic power.

3. Attachments and Protection

In order to protect Trident components from dust, liquids, and corrosive gases, the system is equipped with necessary accessories, including End Caps (for column end protection), Terminal Cover (for protecting unused wiring terminals), and Slot Cover (for protecting unused slots).

Environmental adaptability and global compliance

1. Environmental specifications

The Trident system is designed specifically for harsh industrial environments. Its operating temperature range is -4 ° F to+158 ° F (-20 ° C to+70 ° C), and its storage temperature range can reach -40 ° F to+185 ° F (-40 ° C to+85 ° C). The system can withstand non condensing relative humidity of 5% to 95% and has passed the G3 level corrosion environment test defined by ISA S71.04 standard.

In terms of mechanical tolerance, the system can withstand sinusoidal vibrations of 1G @ 10 to 150 Hz per axis, as well as impacts of 15G per axis lasting 6-11 milliseconds. In terms of electromagnetic compatibility (EMC), Trident strictly follows the IEC 61000-4 series standards, including anti-static discharge (4kV contact/8kV air), radio frequency interference, electrical fast transient/pulse group, and surge immunity, ensuring stable operation in complex electromagnetic environments. Meanwhile, its conduction and radiation emissions comply with CISPR 16 and CISPR 11 Class A standards.

2. International certification

Trident controllers have been certified by multiple authoritative certification bodies worldwide and can be used for safety critical applications worldwide.

CSA (Canadian Standards Association): Certified to comply with multiple electrical safety standards including CAN/CSA-C22.2 No.0-M91, UL 3121-1, etc.

CE Mark (EU): Based on T Ü V assessment, compliant with EU EMC Directive 89/336/EEC and Low Voltage Equipment Directive 72/23/EEC. Note: To meet CE requirements, MP and CM modules must be installed inside a metal casing.

FM (Factory Mutual Assistance): Certified for use in Class I, Division 2, Temperature T4, Groups A, B, C, and D hazardous locations.

T Ü V Rheinland: Certified to comply with IEC 61508 (Functional Safety), EN50156-1 (Furnace Equipment), NFPA 85 (Boiler and Combustion Systems), SEMI S2-0200 (Semiconductor Equipment), and ATEX Directive (Explosion proof).

In summary, Trident controllers have become an ideal choice for industrial safety instrumented systems due to their precise triple redundant architecture, rich modular I/O options, strong environmental adaptability, and comprehensive international certifications. Whether dealing with harsh physical environments or meeting the highest level of functional safety standards, Trident has demonstrated outstanding reliability and professional performance.
