Honeywell FC-BKM-0001 Battery and Key Switch Module

This battery and key switch module provides secure power backup and access control for Honeywell systems. The FC-BKM-0001 combines emergency power storage with a physical key-lock mechanism for authorized operation. Its integrated design simplifies cabinet installation while offering two critical functions in one unit. This module ensures system integrity during power fluctuations and restricts unauthorized access.

Battery Specifications and Power Backup Capabilities

The FC-BKM-0001 incorporates a rechargeable lithium-ion battery with a capacity of 1200 mAh. This battery provides approximately 30 minutes of backup power for a standard S300 controller under full load. The module automatically switches to battery mode when it detects a main power loss. Additionally, the built-in charging circuit maintains the battery at optimal capacity without overcharging.

Physical Dimensions and Installation Details

The FC-BKM-0001 measures 100mm wide, 80mm high, and 60mm deep. This module weighs approximately 0.5 kilograms and mounts onto standard DIN rail systems. The front panel features the key switch mechanism and three LED status indicators. A removable 6-pin terminal block provides connections for power input and system monitoring. Furthermore, the housing includes a locking tab to secure the module firmly in place.

Energy Management and Safety Features

This module utilizes advanced battery management circuitry to prevent deep discharge conditions. The FC-BKM-0001 includes overvoltage and overcurrent protection for both charging and discharging operations. The key switch mechanism requires physical key rotation to enable or disable the backup function. Additionally, the module provides a dry contact output for remote status monitoring. Consequently, these features enhance both operational safety and system reliability.

System Integration and Operational Use

The FC-BKM-0001 connects directly to Honeywell S300 controllers and termination assemblies. You can use the key switch as a master enable control for critical process operations. The battery backup ensures uninterrupted controller memory retention during brief power outages. Therefore, this module serves as an essential component for applications requiring high system availability.
