Rockwell releases advanced vacuum controller

A Rockwell Automation product story
Edited by the Engineeringtalk editorial team Sep 11, 2008

Rockwell Automation has introduced the Allen-Bradley IntelliVac Plus controller, a vacuum contactor control solution.

IntelliVac Plus controllers are used to control the Allen-Bradley Bulletin 1502 medium voltage contactors.

Together, they are the primary components within the Allen-Bradley Bulletin 1500 and Allen-Bradley Bulletin 1900 Centerline medium voltage motor controllers.

This vacuum contactor technology for AC motor control is a lightweight, compact design, requiring no additional low voltage panel space compared to electromechanical control circuits.

It is possible to retrofit existing Bulletin 1500 and Bulletin 1900 controllers with the IntelliVac Plus controller.

The IntelliVac is supplied with standard DeviceNet communications with Allen-Bradley DeviceLogix control.

It will also support multicontactor (MC) control schemes, with up to four IntelliVac MC units connected on RS 485, and DeviceLogix technology preconfigured for standard medium voltage controller logic.

It includes features such as a real-time clock, extended contactor close-time monitoring and tracking of contactor usage.

Rockwell said that its IntelliVac controller allows consistent vacuum contactor performance and minimises external control circuitry and wiring, reducing repair time and expenses.

The controllers also feature universal input voltage (100-240 VAC, 50/60Hz and 100-250 VDC), altitude compensation and power loss ride through (TDUV and antikiss protection).

They can be used in electromechanical, reduced voltage solid state and variable frequency drive (VFD) motor control systems, in a variety of medium voltage controller applications.
