Allen-Bradley 2707-M485P3 DTAM Micro USNT

The Allen-Bradley 2707-M485P3 DTAM Micro is a compact, panel-mount micro operator interface that presents PLC data on a 1.0 x 3.0 inch LCD with a yellow-green backlight across two lines of 20 characters and about 244 screens of on-device memory. It uses an eight-key keypad for quick input and supports ASCII data exchange, making it suitable for simple operator prompts and status displays in industrial environments. The RS-485 version (DH-485) employs a bottom 9‑pin connector for serial communication with AB SLC/ PLC‑5 networks (the RS‑232 variant is cataloged as 2707-M232P3); it is powered from 18–30 V DC. The enclosure is rated for indoor use with NEMA 4, 12, 13 protection, supporting reliable operation in factory settings. Designed to interface with PLC‑5 DF1 networks and AB DH‑485 networks, it can also connect to MicroLogix 1000 systems via the appropriate interface. Note that the DTAM Micro family has been discontinued by the manufacturer, so remaining units are typically found as surplus or refurbished from third‑party suppliers.
