Allen-Bradley 2707-MVP232 MicroView Operator Interface Module

Allen-Bradley 2707-MVP232 MicroView Operator Interface Module

Configured for monitoring and manipulating controller process data through an RS-232 link, the Allen-Bradley 2707-MVP232 (2707-MVP232 MicroView Operator Interface Module) provides keypad input and a 2-line x 16-character display for MicroLogix processors. It supports DF1 communication, up to 50 stored screens, and recipe operations.

Hardware Specifications

RS-232 / DF1 Communication and Operator Interface

The 2707-MVP232 uses an 8-pin mini-DIN RS-232 interface for communication with MicroLogix processors. The specified maximum communication distance is 50 ft (15 m). The operator interface accepts ASCII input through the keypad and displays controller-related process information on a 2-line x 16-character monochrome display.

The keypad includes F1 and F2 function keys, numeric keys, and navigation keys. The supplied data specifies a mechanical operational life of 1 million operations with an actuating force of 16 oz (453 g).

The unit operates from 11-25 VDC and has a stated power consumption of 1.5 W. Input current is specified as 140 mA at 11 V and 60 mA at 25 V.

Field Installation Guidelines

• Verify that the available supply is within the specified 11-25 VDC input range before energizing the module.
• Observe the specified RS-232 communication distance limit of 50 ft (15 m).
• Use appropriate RS-232 signal wiring and maintain physical separation from high-voltage and high-current conductors where practical.
• Route communication wiring to minimize exposure to motor, contactor, and other high-noise switching circuits.
• Terminate the 8-pin mini-DIN communication connection securely and inspect the connector for mechanical damage before commissioning.
• Connect the DC supply with correct polarity and verify the supply voltage at the module terminals before operation.
• Mount the operator interface securely in the specified panel arrangement and ensure that the display and keypad remain accessible.
• Do not perform wiring changes while the unit is energized unless the applicable plant electrical procedures specifically permit the operation.
• For shielded communication cable, terminate and bond the shield according to the site grounding and EMC practice applicable to the RS-232 installation.
