ICS Triplex T8110 Trusted TMR Processor Module

Configured for high-integrity safety logic execution and system control in fault-tolerant automation platforms, the ICS Triplex T8110 (T8110 TMR Processor Module) provides direct physical/electrical execution. The hardware operates across triple redundant Inter-Module Bus (IMB) backplane architectures, executing hardware-implemented fault tolerance (HIFT) without relying on software voting overhead.

Hardware Specifications

Triple Modular Redundancy and SIL3 Execution

The T8110 architecture relies on Triple Modular Redundancy (TMR) incorporating 2oo3 (two-out-of-three) hardware voting logic across three isolated processing channels. Each channel independently processes input signals, executes IEC 61131-3 logic routines, and votes on output states to eliminate single-point failures. Integral fault-tolerant state execution enforces a SIL3 safety integrity level in accordance with IEC 61508. Galvanic isolation and continuous internal diagnostic self-tests maintain fault containment boundaries. If a processing fault occurs on a single channel, the module degraded state seamlesslytransitions to a 2-1-0 or 3-2-0 voting scheme, preserving system output availability without disrupting process control loops.

Frequently Asked Questions

Q: Can the T8110 processor module be replaced while the system is powered and online?

A: Yes, the module supports live hot-swapping under full operational power. The replacement unit synchronizes automatically with the active TMR channels via the backplane without interrupting safety logic execution or requiring a manual program reload.

Q: What are the internal power supply configuration requirements for the processor chassis?

A: The module accepts redundant dual 20-32 VDC inputs. Both power feeds must be operational and grounded according to backplane specifications to meet SIL3 fault-tolerant power distribution standards.

Field Installation Guidelines

1. Chassis Alignment & Insertion: Ensure the target chassis slot is free of debris. Guide the module along the chassis card rails until the rear IMB backplane connectors align. Apply firm, even pressure to seat the multi-pin DIN connectors. Lock the top and bottom retaining screws to secure the physical connection and establish chassis earth bonding.
2. Grounding & Shielding: Connect the system chassis to a dedicated low-impedance Instrumentation Earth (IE) bus. All RS422/RS485 communication line shields must be grounded at a single point to prevent ground loop currents from introducing common-mode noise into the IMB backplane interface.
3. Power Wiring Constraints: Route primary and secondary 24 VDC power feeds through separate wire ducts to maintain physical channel separation. Ensure supply voltage remains within the strict 20-32 VDC operating boundary under maximum module thermal load.
4. Time Sync Wiring: When utilizing the IRIG-B port for system-wide sequence-of-events (SOE) timestamp synchronization, install twisted shielded pair cable terminated with proper end-of-line impedance to maintain signal integrity across long runs.
