Triconex3008Tricon TMR Enhanced Main Processor Module, MPC860 32-Bit 50 MHz, 16 MB DRAM, 24/48 V DC, Hot-Swappable

Product Description

What this part is

The Triconex 3008 is the enhanced Main Processor (MP) module for the Tricon triple-modular-redundant safety system. US-made new old stock.

Published specifications

Processor: Motorola MPC860 32-bit at 50 MHz. Memory: 16 MB DRAM, 32 KB battery-backed SRAM, 6 MB Flash. Power: 24 V DC or 48 V DC.

TriBus: 25 Mbps, CRC protected, 32-bit DMA. Diagnostic Port: optically isolated RS-232 at 500 V isolation. TriClock Drift: typically plus or minus 2 seconds per day. Atmospheric Rating: Class G3 for harsh industrial atmospheres.

Decoding the designation

3008 — the enhanced Main Processor model in the Tricon module range, also written MP-3008.

MP — Main Processor, the module that executes the control program for one redundant leg.

TMR — triple modular redundant, the Tricon architecture in which three legs run the same program in parallel and vote on the result.

What these specs mean in practice

Each Main Processor executes the control program independently and drives its own I/O subsystem, and the three legs vote through the TriBus. That structure is what carries the platform into SIL 3 safety-instrumented duty: a single faulty leg is outvoted and reported rather than acted on.

The 25 Mbps CRC-protected TriBus with 32-bit DMA is the path the three legs use to exchange and compare data each scan, so its bandwidth sets how much process data can be voted within a scan. The optically isolated RS-232 diagnostic port at 500 V isolation keeps a service laptop galvanically separated from the control system. TriClock drift of about two seconds per day sets how often an external time source needs to resynchronise the system for sequence-of-events work.

Quantity and configuration

Sold as 1 Pc — one Main Processor module. A Tricon main chassis is populated with three Main Processors, one per redundant leg, so a single 3008 serves as a spare or a leg replacement.

Mounting data

The module installs in a Main Processor slot in the Tricon main chassis. Modules are hot-swappable with continuous online diagnostics, so one leg can be replaced while the system keeps running. Programming supports ladder logic, function block diagram and structured text.

Interchange guidance

Triconex is part of Schneider Electric. A direct replacement matches Triconex model 3008, also catalogued as MP-3008.
