The Spectrum 2707-M232P3sc is a black, Rev. 10 DTAM Micro Operator Interface (SC variant) used as a serial operator terminal in legacy AB automation systems. It communicates with older PLCs via RS-232 (2707-M232P3) and has an RS-485 family counterpart (2707-M485P3) for networked DH-485 connections. Spectrum Controls lists the 2707-M232P3sc as a discontinued part, confirming its status as legacy hardware. Typical applications include local operator input and status viewing on PLC-5/SLC 500 controllers where a dedicated serial HMI is required.
