Allen-Bradley 2707-L8P2 Operator Interface Terminal

The Allen-Bradley 2707-L8P2 DTAM Plus Operator Interface Terminal is a discontinued industrial display and control unit designed for interacting with programmable logic controllers. Featuring a 4-line by 20-character LCD display, 25 function keys, and an 8K memory capacity, this compact terminal connects via an RS-232/485 communication port and supports versatile AC/DC power supply inputs.

Technical Specifications

Key Operational Features

The 2707-L8P2 DTAM Plus serves as a robust operator interface for monitoring real-time process data, viewing system diagnostic messages, and modifying controller registers directly on the factory floor without requiring a programming terminal.

The integrated 25 function keys allow operators to trigger specific control routines, navigate menus, or acknowledge alarms quickly. Because it relies on an RS-232/485 communication link, proper cabling and termination are essential for maintaining stable serial data transmission across industrial noise environments.

Frequently Asked Questions

Q: What type of power supply does the 2707-L8P2 require? A: This unit uses the P2 power supply option, supporting an input range of 85-265 VAC at 47-440 Hz or 110-300 VDC.

Q: Can this terminal be used as a direct replacement for other DTAM models? A: Compatibility depends on the specific PLC communication protocol, memory size requirements, and firmware configuration of your application. Always verify the exact catalog suffix and communication settings before swapping units.
