Honeywell 05411901 Touch Panel Switch Decoder Module

Product Description

The 05411901 Touch Panel Switch Decoder from Honeywell is a compact interface module engineered to interpret multi-position touch or membrane switch inputs used in operator panels. This decoder performs active scanning and signal conditioning to translate raw switch matrix inputs into stable, controller-readable digital outputs.

Designed for integration inside legacy and modern Honeywell HMI/MMI/OIT assemblies, the module emphasizes electrical noise immunity, input stability, and long-term reliability under continuous operation. Its scanning logic ensures accurate recognition of operator commands, even in environments with vibration, EMI, or fluctuating power conditions.

Key Functional Overview

This decoder continuously scans up to nine discrete switch positions, applies internal debouncing and filtering, and delivers clean logic-level signals to downstream interface or control boards. The result is consistent operator input recognition without false triggering or contact bounce errors.
