Product Overview
Technical Correction Note: The original datasheet text mistakenly references this component as a “Central Processor Unit,” “Power Supply Unit,” and “Ethernet router.” The Honeywell 10002/1/2 is strictly a physical, panel-mounted Run/Stop Keyed Switch Module engineered specifically for the Honeywell Fail Safe Control (FSC) system architecture.
The Honeywell 10002/1/2 functions as a critical safety override interface within industrial automation setups. This dedicated hardware module governs the operating state of safety-instrumented systems via mechanical key validation.

Functional Characteristics and Safety Features
The 10002/1/2 switch module provides a tamper-resistant mechanism for changing logic execution modes. Because process environments demand absolute security, this unit relies on a physical key to toggle between the active operational loop and system stop states.
Consequently, the hardware prevents unauthorized personnel from manipulating critical safety configurations during live facility operations. The underlying printed circuit board integrates heavy-duty contact blocks to ensure crisp signal switching without internal arc degradation.
Furthermore, the design matches the exact backplane dimensions of Honeywell FSC control panel enclosures. This alignment streamlines field retrofitting and optimizes terminal point accessibility during routine compliance testing.
