Overview
The 1785-ME32 is a memory module designed for the Allen-Bradley PLC 5 series. It provides 32K words of memory and functions as a program backup device. This EEPROM (Electrically Erasable Programmable Read-Only Memory) module stores small amounts of data, such as calibration tables and device configurations, ensuring that data is retained even when power is removed. It supports the standard PLC-5 processors and includes a control coprocessor expansion port.
