1503vc-bmc5 IntelliVAC Contactor Control Module
This document contains information for the Allen-Bradley Bulletin 1503VC
IntelliVAC™ control module. The Bulletin 1503VC is used to control the AllenBradley Bulletin 1502 vacuum contactors that are a significant component of the
Bulletin 1500/1900 CENTERLINE Medium Voltage Motor Controllers
offered by Rockwell Automation. IntelliVAC is an efficient and flexible solution
for controlling medium voltage vacuum contactors used in motor starter and
feeder applications.
An IntelliVAC control module may also be provided as a loose OEM component,
for use with a Bulletin 1502 contactor by a third party (OEM).

• A range of supply voltage (110 – 240V AC 50/60 Hz, 110 – 250V DC) allows implementation in multiple applications.
• Consistent vacuum contactor pick-up time (at a given supply voltage) ensures repeatable performance.
• Selectable vacuum contactor drop-out time improves coordination with upstream power fuses.
• Electronic altitude compensation (Bulletin 1502 400 A only) eliminates mechanical compensation required for altitudes above 1000 meters
(Bulletin 1502 800 A contactors include a user-friendly mechanical altitude adjustment).
• Power loss ride-through (TDUV) allows the vacuum contactor to remain
closed during short power loss (may require an optional external capacitor, dependent on ride-through time).
• Anti-kiss and anti-pumping protection ensure that the vacuum contactor
close – open sequence occurs as expected, avoiding rapid reclosure due to faulty control devices.
• Delayed restart protects the vacuum contactor by ensuring that the rated duty cycle is not exceeded.
• Temporary jog function (electrically held contactors only) allows the motor to be positioned for process set-up.
