Allen-Bradley 2706-LV2RX AC Input Power Supply

Allen-Bradley 2706-LV2RX/A DataLiner is the DL40 Plus two-line operator interface module designed to display essential process information from Rockwell Automation PLCs. It features a 2-line by 20-character Vacuum Fluorescent Display (VFD) with brightness adjustable up to 100% and includes 128 KB of RAM for message storage and local data. The unit is powered from 100–240 VAC, 50/60 Hz, drawing about 0.60–0.25 A (60 VA), and identified in Series A, Revision C configurations. Communications options include RS-232 and RS-485 serial ports, with common baud rates such as 300, 1200, 9600, and 19200 bps on RS-232 and 2400/4800 bps on RS-485 for select DataLiner variants, enabling display of PLC messages or simple operator prompts and status information; some configurations also support Allen-Bradley Remote I/O Link for discrete I/O or block transfers. As part of the DataLiner family, the LV2RX/A is typically used as a compact human–machine interface for legacy PLC-5 or SLC 500 systems, storing and presenting controller data locally while providing straightforward visibility into fault statuses and process values in industrial environments.
