Product Description

Product Overview

Honeywell 05701-A-0325 is a DC Input Card designed for Honeywell System 57 gas detection control systems. It provides the main DC power input interface for the system rack and distributes power through the sub-rack backplane to installed control and interface modules.

The module accepts an external nominal 24VDC supply and includes power protection features such as fuse protection, reverse polarity protection, and RFI filtering to improve system reliability in industrial environments.

As a key power supply interface component in legacy Honeywell System 57 installations, the 05701-A-0325 is commonly required for maintenance, repair, and replacement projects where existing gas detection infrastructure remains in service.
