About the 57C435A

The 57C435A is an AutoMax Processor Module made by Reliance Electric. This module may have also been sold under the Baldor Reliance or ABB product lines at one point, but it has since been discontinued. AX Control still attempts to keep the 57C435A in stock even if it has become hard to find.

The 57C435A was originally based on a 32-bit Motorola 68020 microprocessor. It is a 7010 processor module with a 25 mHz CPU speed and a 512K parity RAM. It has the ability to run programs that will control other modules within the AutoMax system. There are three languages that can be used to program this processor: Ladder Logic, Control Block, and Basic.

The 57C435A’s faceplate has several key features on it. There is a bank of LED indicators. There are two small green LEDs in this grouping that are labeled BAT OK and OK. There are also two 7-segment LED fault code indicators that are labeled 1st and 2nd. There are two RS-232 ports below the LEDs that are labeled Port A and Programmer/Port B. On the right side of the module is a user-replaceable battery backup. This battery protects the data held within the RAM for a minimum of 186 days when it suffers a power loss. This module can be plugged directly into an AutoMax card rack assembly system into its card slots. This module takes up a single card slot on the rack.  More than one processor can be plugged into the rack at a time.
