700-375-OLC41 Product Description Helmholz 700-375-OLC41, also named EEPROM memory module, is an alternative memory card for Siemens SIMATIC S5 PLC system. It is designed to store user PLC programs and configuration data, supporting program backup and offline preservation for old automation equipment renovation.

This module delivers reliable program storage for PLC control tasks. The program storage supports switchable 8KB /16KB memory capacity. The program storage retains program data without continuous power supply after data writing. Stable program storage prevents program loss caused by battery failure.

The built-in EEPROM chip achieves steady data holding. The data holding supports program read and write operations via S5 PLC programming device. The data holding can keep stored data for long service life. Accurate data holding ensures control program can be loaded to S5 CPU normally.

Plug-in card structure brings convenient on-site replacement. On-site replacement can be directly inserted into S5 CPU memory slot. On-site replacement adopts standard gold finger connector design. Flexible on-site replacement is widely used for legacy SIMATIC S5 system spare replacement.

700-375-OLC41 supports data protection and program verification function, equipped with standard edge connector compatible with S5 CPU memory socket. It adopts non-volatile EEPROM chip without UV erasure requirement. Widely applied in conveyor machines, packaging equipment and traditional process production lines. This product is discontinued by Helmholz, mainly supplied as industrial spare parts, complying with SIMATIC S5 memory module standards.
