Technical Specifications​

Manufacturer: Triconex

Part number: 9000-025

Cable length: 25 feet

Configuration: passive, factory-molded interconnect

Topology: triplicated multi-core I/O bus expansion

Impedance matching: built into cable and connector geometry

Shielding: heavy-duty specialized shielding for TMR environments

Termination: no configuration jumpers or DIP switches

Bus setup: managed by active backplane and controller firmware

Functional Features​

The cable maintains separated triplicated channels to avoid cross-talk and single-point signal degradation. The molded connectors provide fixed pin alignment for main-to-expansion rack installation. The passive design requires no user configuration.

Application Scenarios​

Tricon TMR safety controllers, remote I/O expansion racks, critical process shutdown systems, burner-management interfaces, and distributed safety architectures requiring long chassis separation.

Material And Structure​

The assembly uses multi-core triplicated conductors with impedance-controlled pairs, industrial-grade molded connectors, and overall shield jacketing suitable for control-room and cabinet installations.

Working Principle​

The controller transmits synchronized TMR bus data through three independent channels. The cable carries each channel with matched impedance and shielding to the expansion backplane. The active backplane terminates the bus and updates remote I/O states without external configuration.

Installation Requirements​

Install with the controller in a managed shutdown state when replacing an online bus cable. Route the 25-foot cable without sharp bends that deform the molded connectors. Keep the cable separated from high-voltage feeders where the system design requires signal-integrity segregation.

Usage Precautions​

Do not disconnect the cable while the controller is online; removing an active expansion bus forces remote I/O into configured safe states. Do not replace it with commercial RS-485 or standard serial cable because commercial cables lack triplicated geometry, impedance matching, and TMR-grade shielding. Follow management-of-change procedures before any bus reconfiguration.
