Honeywell 10002/1/2 Run/Stop Key Selector Module

Applications

The Honeywell 10002/1/2 Run/Stop Key Selector Module is designed to provide secure operational mode control within Honeywell modular automation systems. It enables authorized personnel to switch between RUN and STOP states using a physical key mechanism, ensuring controlled access to critical system functions.

This module is typically deployed in:

• Distributed Control System (DCS) cabinets

• Process automation control panels

• Power generation control systems

• Oil & gas production platforms

• Chemical and petrochemical facilities

• Industrial plants requiring restricted operational control

Its physical key-based switching mechanism adds an additional layer of operational security, particularly valuable in regulated and safety-sensitive environments.

Advantages

The 10002/1/2 module combines operational simplicity with robust industrial reliability.

• Physical key-based RUN/STOP control for enhanced security

• Prevents unauthorized mode changes

• Seamless integration with Honeywell rack systems

• Industrial-grade mechanical durability

• Clear operational state selection

• Compact design suitable for dense cabinet layouts

By incorporating a hardware-level control interface, the module reinforces procedural safety and ensures that system state changes are intentional and authorized.
