ABB 07 PR 82 R1 Memory Module

This memory module stores user programs and system parameters safely. The ABB 07 PR 82 R1 serves as an expansion memory for ABB Procontic systems. You can insert this module directly into the central unit’s memory slot. Its non‑volatile design retains data without external power.

Physical Dimensions and Form Factor

The ABB 07 PR 82 R1 measures 6.5 cm in total length. Its width reaches 4.0 cm with a height of 1.2 cm. This memory module weighs only 0.04 kg. A 40‑pin dual in‑line connector interfaces with the host unit. Two plastic latches secure the module firmly in its socket.

Memory Organization and Capacity

This module provides 64 kB of EEPROM storage space. The ABB 07 PR 82 R1 divides memory into two separate banks. Each bank stores either program code or configuration data. The module supports up to 10,000 write cycles per memory cell. Consequently, you can update programs frequently without wear concerns.

Compatibility and System Integration

The ABB 07 PR 82 R1 fits ABB Procontic central units exclusively. You can install this module in the designated memory expansion slot. The host system automatically recognizes the module upon power‑up. Therefore, no additional configuration steps are necessary.

Data Protection and Write Security

A hardware write‑protect switch prevents accidental data overwrites. You can enable this protection by sliding the side switch. The ABB 07 PR 82 R1 also includes software access control. This dual protection ensures critical program integrity at all times.

Installation and Handling Notes

Insert the module gently into the 40‑pin socket. Press evenly until both latches click into place. Avoid touching the gold‑plated connector pins directly. Static discharge can damage the internal memory circuits. Use an anti‑static wrist strap during installation.
