Intellivac Contactor Control Module
Bulletin 1503VC
Intelligent drive and closed-loop
telemetry for Bulletin 1502
Vacuum Contactors
(400A and 800A frameworks)
The 1503VC-BMC4 is an IntelliVAC vacuum contactor control module manufactured by Rockwell Automation. It is used in the 1500/1900 CENTERLINE medium-voltage motor controller.
The module has a built-in dedicated microprocessor.
DIP switch hardware configuration matrix
High reliability TDUV
IntelliVAC is an efficient and flexible solution for controlling medium voltage vacuum contactors used in motor starter and feeder applications. IntelliVAC may be used to control both 400 and 800 Amp contactors. Electrically held and mechanically latched contactor types can be controlled with IntelliVAC.IntelliVAC is easily configured for a wide variety of medium voltage motor and feeder control applications. It is configured using DIP switches, located within the enclosure (front side).

Thermal Power
Controls the medium-voltage vacuum contactors in Bulletin 1500 Motor Control Centers (MCC) for boiler feed water pumps.
Petrochemical Refining
Drives high-voltage reciprocating and centrifugal compressors utilized in hydrocracking units.
Oil & Gas
Manages the medium-voltage starter circuits for heavy-duty crude oil mainline transit pumps.
Iron & Steel
Controls the high-capacity axial blowers and cooling water circulation pumps surrounding the blast furnace.
Pulp & Paper
Drives the heavy-duty wood chippers, pulpers, and high-pressure steam boiler fan grids.
Air Separation
Manages the starter sequence for massive integrally geared main air compressors (MAC).
When deploying the 1503VC-BMC4 control module, engineers must meticulously verify its Series designation , as hardware revisions dictate completely different DIP-switch configuration matrices for drop-out delays and altitude compensation. It is critical to precisely configure the onboard DIP switches to match the exact contactor framework (400A or 800A) and downstream power fuses to guarantee accurate protection coordination and prevent catastrophic vacuum tube failures. Prior to initial energization, technicians must confirm the wiring harness integrity and ensure the 110–240V AC/DC supply voltage remains highly stable to safeguard the onboard microprocessors. Lastly, while the system features advanced TDUV ride-through logic, manual extraction or troubleshooting inside the medium-voltage enclosure must strictly adhere to plant safety isolating protocols to avoid high-voltage arc hazards.
It is an IntelliVAC Contactor Control Module manufactured by Rockwell Automation, designed as the intelligent core to drive and control Bulletin 1502 vacuum contactors (400A and 800A frameworks).
How to use and configure the 1503VC-BMC4 control module?
Technicians mount it independently inside medium-voltage motor control centers (MV MCC), connect the control wiring harness, and configure parameters such as drop-out delays and altitud.e compensation using the board-mounted DIP switches
What are the input voltage requirements for the 1503VC-BMC4?
It features a universal input power deck that accepts a wide range of voltages, supporting 110V to 240V AC (50/60 Hz) and 110V to 250V DC.
What is the role of selectable drop-out time in the 1503VC-BMC4?
It enables the user to select specific contactor drop-out delay times to optimize time-based protection coordination with upstream power fuses, preventing contactor destruction during short-circuits.
What is the difference between 1503VC-BMC4 Series D and Series E?
Series D features older hardware with a single row of DIP switches (now discontinued), whereas Series E represents the active generation featuring dual-row DIP switches and a redesigned control motherboard.
