Industrial 45C270 AutoMax Memory Expander Module

Reliance Electric AutoMax 45C270 Memory Expander Module adds 8K of non-volatile memory to the AutoMate 40 Logic Processor system. This long, slim card in a black enclosure mounts in an AutoMax Multibus rack using two mounting brackets and screws, with two male backplane connectors on the rear that plug into the rack’s female slots, while a white label on the side identifies the card’s capabilities. Front-panel LEDs labeled ACTIVE, READY, and ERROR provide at-a-glance status, aiding quick diagnostics. The 45C270 is one of four available memory-card sizes for AutoMate memory expansion; this model provides 8K expansion and can be used singly or in pairs to increase system memory. When combined with the AutoMax 40X processor, total non-volatile memory can reach up to 104K x16, or 32K x16 in certain configurations, depending on the specific rack and expansion setup. The unit is typically listed in catalogs as an 8K memory expander for Reliance Electric’s AutoMax/AutoMate family, with alternate catalog references such as 802820-77R in some listings. This expansion module is intended for installation in industrial control environments using Reliance Electric AutoMax racks, enabling larger programs and data storage without replacing the core processor.
