GE 8810-HI-TX Analog Input Module

Overview

The GE 8810-HI-TX is a high-integrity 8-channel analog input module engineered for safety-critical and hazardous applications. As part of the PAC8000 I/O family, it supports reliable 4–20 mA inputs from 2-, 3-, and 4-wire transmitters. The module integrates HART pass-through and acquisition, enabling advanced diagnostics and smart device communication. Designed for industrial environments, it delivers accuracy, failsafe behavior, and certified hazardous area protection.
