The 1SFB527068D7084 is a contactor control circuit board manufactured by ABB. It is the internal unit for ABB contactors, including models AF400, AF460, AF580, AF750, and AF1250, where it controls coil circuit pick-up and connects to the main control system.
Smart Coil Control
Onboard Modbus RTU / RS-485
Vibration-Resistant Connection
The ABB 1SFB527068D7084 contactor control board features standardized electrical connection ports. The board edge is equipped with 3-pin screw clamp terminals for connecting the external 24V DC control power and control switch signal wires. Its communication interface utilizes a two-wire RS-485 architecture, connecting to the fieldbus network via shielded twisted-pair cables to upload the contactor’s operating status and open/close signals to the host computer. For field installation, this board must be secured into specific rails or mounting slots inside the compatible contactor housing.
The 1SFB527068D7084 Contactor Control Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (ABB).
