Products Description
The ABB SD812F 3BDH000014R1 is a 24 V DC power supply module manufactured specifically to operate with ABB AC 800F controllers, including the PM 802F and PM 803F models. This unit converts incoming power to a regulated 24 VDC output, providing stable operating voltage for the controller and its connected field devices.
As an accessory within the AC 800F ecosystem, the SD812F mounts onto the DIN rail adjacent to the controller. The module requires system firmware version V7.1 SP2a or higher to function correctly. It serves as both an original component for new installations and a direct replacement spare part for maintenance activities.
