Internal Design and Non-Volatile Storage

This program memory module contains two EPROM chips with quartz windows. The ABB 07 PR 63 R2 retains all program data without any battery backup. UV light erases the memory contents through the windows for reprogramming. The chips store PLC logic, configuration parameters, and text messages permanently. This non-volatile design guarantees data integrity during long-term power loss. You will never need to replace batteries or worry about data decay.

Installation and Programming Guide

First, power down your Procontic PLC completely before handling this module. Next, locate the memory slot on your CPU board. Then, align the 32 gold-plated pins carefully with the socket. Press the module downward until it seats firmly in place. Use a standard EPROM programmer with 12.5 V DC to write data to the chips. Cover the quartz windows with opaque labels after programming to prevent accidental erasure. This module works with ABB Procontic CPU boards and compatible systems. Expose the windows to strong sunlight or fluorescent light can slowly corrupt stored data.
