Overview
Essential details：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 Allen-Bradley Bulletin 1502 vacuum contactors that are a significant component of the Bulletin 1500/1900 Centerline Medium Voltage Motor Controllers offered by Rockwell Automation.
An IntelliVAC control module may also be provided as a loose component, for application with a Bulletin 1502 contactor by a third party (OEM).
Description 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 Features
A wide range of supply voltage (110 – 240 V AC 50/60 Hz, 110 – 250 V 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 (400 A only) eliminates mechanical compensation required for altitudes above 1,000 meters (800 A contactors include a user-friendly altitude adjustment)
Power loss ride-through (TDUV) allows the vacuum contactor to remain closed during short power loss (may require an optional external capacitor, dependant on ride-through time)

1503vc-bmc5 IntelliVAC™ Contactor Control Module
IntelliVAC Features (cont.)
Anti-kiss and anti-pumping protection ensure that the vacuum contactor close – open sequence occurs as expected, avoiding rapid re-closure 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 IntelliVAC Versions
Series A There are two versions of IntelliVAC control. The first type is used to control vacuum contactors that are electrically held, with a single electrical coil that is economized electronically. The second is used to control mechanically latched vacuum contactors.
Series B There is a single version of IntelliVAC, to control both electrically held and mechanically latched vacuum contactors.
Refer to Chapter 6, for catalog numbers for each version of IntelliVAC.
A Series B IntelliVAC module can be used to replace a Series A module.
The IntelliVACcontrol modules are mounted using two (2) screws (see Figure 1.3). They are typically located in the low voltage control panel of the medium voltage controller (Bulletin 1500/1900 controllers, in the case of Rockwell Automation).
IntelliVAC is interfaced to the Bulletin 1502 vacuum contactors using a “quick” connector, located at the module, a wire harness and “quick” connector at the contactor. Control power and other control circuit connections are similarly achieved with “quick” connectors.
Configuration
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).
Please refer to Chapter 4 for information.
Bulletin 1500/1900 controllers are shipped with IntelliVAC preconfigured for the required application. Please refer to the documents provided with the order.
