Mitsubishi Q1MEM-128SE 64K SRAM PLC Expansion Module

The Mitsubishi Q1MEM-128SE is a 64K SRAM expansion module that fits into the Mitsubishi Q-series PLC backplane. It adds on-board memory for larger program or data tables without tying up a slot on the main CPU memory card. This is a mature product in the field — no longer the hot new thing, but still a solid drop-in spares candidate for existing Q-series panels. It's sourced to order, not sitting on a shelf, so send an RFQ to lock in availability for your line-down situation.
