Honeywell BKM-0001 CC V1.1 power module

Honeywell BKM-0001 CC V1.1 is the Battery&Key Switch Module of Honeywell TDC/Expert PKS series DCS controllers, which is a core spare part for safety and power management inside the controller chassis.
1、 Basic Information
Model: BKM-0001 CC V1.1 (also labeled as FC-BKM-0001/FS-BKM-0001)
Positioning: The controller chassis comes with standard modules, and only one redundant system is required
Origin: United States
Weight: Approximately 0.63-0.66 kg
Size: Approximately 3.5 × 22.5 × 17.5 cm
2、 Core components and functions
Dual battery power supply
Equipped with 2 built-in 9V batteries, each providing backup power for the dual control processors in case of power failure (approximately 10 hours of battery life)
Ensure that key parameters, programs, and states of the controller are not lost in the event of a main power outage
Safety key switch
Force Enable Keyswitch: Force Enable/Unlock Controller, used for debugging, maintenance, and forced operation
Reset key switch: a hardware reset controller used for system restart and fault recovery
Power supply and interface
Power supply: 5 VDC (≤ 10 mA), 24 VDC (≤ 20 mA)
Working temperature: -5 ° C to+70 ° C
Storage temperature: -40 ° C to+85 ° C
system adaptation
Compatibility: TDC500/700/800, Expert PKS C200/C300 controllers
Purpose: Safety and power management for key process control in industrial DCS, power plants, chemical industry, metallurgy, etc

Installation:
It must be plugged and unplugged in a power-off state to avoid static electricity and short circuits
After replacement, it is necessary to check the battery voltage, key switch function, and controller self-test
Redundant systems require synchronous verification of dual controller status
