Reliance Electric 57430-2B Automax Processor Module

Reliance Electric AutoMax 6010 Processor Module, part number 57430-2B (alternate M/N 57C430A), is the 8 MHz central processing unit that powers Reliance’s AutoMax PLC backplane, executing application tasks and coordinating AutoMax I/O and DCS modules. This processor plugs into an AutoMax rack and serves as the system’s control brain, with 256K parity RAM and 32K on-board EPROM for board‑level diagnostics and boot software, plus an on‑board battery backup to protect RAM during power loss. The module measures about 1.3 in x 1.5 in x 7.5 in and weighs roughly 2 lb 0.8 oz, and is manufactured in the United States. In Ethernet-enabled configurations, the AutoMax 6010 family reserves about 134K of RAM for the operating system, leaving roughly 122K for application tasks, while the standard OS uses about 119K RAM with around 137K available for applications on the 57C430A/57430-2B platform. The 57430-2B designation is identical in form and function to the 57C430A AutoMax 6010 Processor Module, making it a faithful option for replacing or refurbishing legacy AutoMax hardware in automation systems requiring reliable PLC processing and synchronization.
