Description
Overview
The 8810‑HI‑TX Safety Analog Input Module is part of GE’s PACSystems SafetyNet platform, designed for applications requiring certified SIL2‑level signal acquisition. It provides secure processing of analog field inputs and incorporates hardware‑based diagnostics to ensure predictable behavior in safety‑critical environments. The module is installed on dedicated carriers that manage both mechanical retention and internal communication pathways.
Functional Characteristics
The module offers eight independent analog input channels, each monitored by continuous self‑diagnostic routines. These routines verify channel integrity, internal circuitry health, and communication status. If a condition arises that could compromise safety, the 8810‑HI‑TX transitions into a failsafe state by halting input scanning and de‑energizing outputs, while simultaneously recording diagnostic information for post‑event analysis.
The module operates within a 1oo1D (one‑out‑of‑one with diagnostics) architecture, eliminating the need for “proven‑in‑use” justification and ensuring compliance with modern safety standards. Field wiring is connected through front‑mounted terminals, while Bussed Field Power (BFP) is supplied from the rear via a 24 VDC feed, typically provided by MTL 8914‑PS‑AC power units.
Safety and Maintenance Features
The 8810‑HI‑TX supports live replacement in hazardous or classified areas, allowing maintenance personnel to remove or install modules without interrupting adjacent channels or system operation. Integrated line‑fault detection continuously monitors wiring conditions, enabling early identification of open circuits, shorts, or grounding faults.
This module is widely used in FB‑8800 logic solver systems, where deterministic safety behavior and high‑availability architectures are required.

FAQ
Q: What safety level does the module support? A: It is designed for SIL2 applications using a 1oo1D diagnostic architecture.
Q: Can the module be replaced while the system is energized? A: Yes. It supports live maintenance without affecting other modules on the carrier.
Q: What power source is required for Bussed Field Power? A: A regulated 24 VDC supply, typically from MTL 8914‑PS‑AC units.
