4-Channel 0-2V Analog Input Card | Honeywell 10102/2/1

Honeywell 10102/2/1 FSC Fail-Safe 4-Channel Analog Input Module

Product Description

The 10102/2/1 (10102/2/1) is a high-integrity, fail-safe analog input module engineered for the Honeywell Fail Safe Control (FSC) system. This module provides four dedicated 0–2 Vdc input channels, designed to interface with both active and passive field transmitters. It is a critical component for safety-instrumented systems (SIS), ensuring precise signal acquisition from field sensors monitoring pressure, temperature, or flow in hazardous environments.

Built for maximum reliability, the 10102/2/1 (10102/2/1) features full galvanic isolation between the analog inputs and the system's 24 Vdc and 5 Vdc power supplies. To maintain safety integrity levels, the module executes continuous onboard self-tests that monitor input filters, crosstalk, and the 26 Vdc transmitter supply. Calibration is highly accessible, allowing for adjustments via front-panel potentiometers or through FSC integrated software tools, ensuring long-term measurement accuracy.
