Automation Direct D2-RSSS Serial Remote IO Slave Module

The D2-RSSS Serial Remote I/O Slave Module is Automation Direct’s serial remote I/O slave for the DL205 DirectLogic PLC family. Designed to reside in a remote I/O base, it acts as the slave in a serial remote I/O network paired with a remote master module to expose its I/O points to the main controller. In DL205 configurations, the remote master (RM‑NET/SM‑NET style) communicates with the base, while the D2‑RSSS installed inside each remote base provides the interface for distributed I/O across the system. This module enables extension of the PLC’s I/O footprint without adding local rack space, supporting distributed control across multiple cabinets. The D2‑RSSS is documented as part of Automation Direct’s DL205 Remote I/O system, and historical product pages show it as a serial remote I/O slave option for DL205. As a legacy/retired product in Automation Direct’s catalog, it represents the established approach to serial remote I/O within the Direct Logic family, commonly found in older installations or projects that rely on serial networks for remote I/O access.
