3ME953.90-1

Product Description

The 3ME953.90-1 memory module delivers abundant storage capacity for System 2005 PLC applications. It provides 512KB of battery-backed SRAM plus 1MB EPROM in a slim package perfect for space-constrained cabinets. This module suits all 2005 series PLC bases and racks to enable easy memory expansion. It runs the PCC operating system designed specifically for high-performance machine control and motion tasks that demand determinism. Installation only takes moments by sliding into any spare slot then securing the locking tab. The unified diagnostics interface allows quick access to view module parameters and status. It also enables direct online PLC program modifications when needed instead of requiring a laptop.

Reliable storage for register data, variables, and instructions comes from the 512KB SRAM section. Battery backup maintains this data for up to 30 days during power loss to prevent faults upon restart. The generous 1MB EPROM then holds the PCC OS firmware plus user PLC application code. The plastic terminal cover provides extra protection from debris or accidental contact with electronics during operation. It still allows access to the removable battery and rotary address switch tucked underneath when out of service.

Whether coordinating an entire automation cell or providing a remote I/O node, the 3ME953.90-1 memory module cost-effectively expands 2005 PLC capabilities. Tight production schedules often leave no time for firmware updates or data backups after startup. This module handles both in a single DIN rail-mounted package. For System 2005 users needing more storage, convenient PCC OS support, and battery backup for retain memory, check out the 3ME953.90-1. It delivers essential extras to keep machines running nonstop across long shifts.
