AutomationDirect D001MC Memory Module

The D0-01MC Memory Module for DirectLOGIC DL05 PLCs is a 32k V-memory, battery-backed RAM cartridge with an integrated real-time clock/calendar, designed exclusively for DL05 CPUs. The unit ships with the D0-MC-BAT battery installed, providing non-volatile memory retention and timekeeping across power cycles. As a plug-in memory module, it attaches to the DL05 memory interface to expand the PLC’s onboard memory with 32 kilobytes of V-memory, enabling persistent storage of configuration data and user data, plus time-stamped events and routine scheduling that rely on the built-in RTC. This combination supports lightweight data logging and time-aware automation in small DirectLOGIC installations, without requiring a separate external clock or additional storage hardware. The D0-01MC is identified by AutomationDirect as part of the DirectLOGIC family, and the product’s country of origin is listed as China or Japan, reflecting its manufacturing provenance. For DL05-based systems where memory preservation and clocked timing are needed, the D0-01MC provides a compact, battery-backed solution that restores memory and time information after a power interruption, helping maintain reliable operation in automated processes.
