Triconex 8310 Main Expansion RXM Chassis Power Module

Triconex 8310 Main Expansion RXM Chassis Power ModuleProduct Overview The 8310 (Model: 8310) is a high reliability 175W power module designed for the Invensys Triconex Triple Modular Redundancy (TMR) safety system. This module is engineered to provide a stable and efficient DC power source to the internal backplane bus, supporting the operation of processors, communication modules, and I O interfaces. Built for mission critical industrial safety applications, the 8310 (Part Number: 8310) ensures

Signal Filtering: 4 ms typical (hardware/software configurable up to 7 ms)

Ground the shield at the driver chassis end only to prevent ground loops

This standardized interface supports the use of pre-wired cordsets and Telefast distribution manifolds

The exact connector standard (SC or ST variant) depends on the specific hardware build option chosen for the facility network

Ground the outer shield at the governor chassis grounding bus terminal only to suppress high-frequency inductive noise

Parameter Specification Details Manufacturer Honeywell Automation Model Designation TK-PRS021 Primary Ordering Part Number 51404305-275 Secondary PCB Internal Reference 51309283-200 Module Classification Control Processor Unit (CPU) Onboard Active User Memory 4 Megabytes High-Speed Non-Volatile RAM Redundancy Architecture Fully synchronized hardware pairing with sub-millisecond failover Network Protocol Interfacing Foundation Fieldbus

the module supplies the 24VDC to the load

This hardware-level flexibility ensures direct compatibility with multi-vendor final control elements operating on standard analog loop interfaces

Model Number: 8310

The system uses capacitors to write volatile data to the onboard non-volatile SD storage card immediately upon input voltage drop-out below 19

The baseline printed circuit board assembly weighs approximately 0

use shielded cabling and ensure proper termination resistors are installed if the 07KT98 is at the end of the bus segment
