HELMHOZ (SIEMENS) 700-952-1KK00 Product Description

Overview

HELMHOZ (SIEMENS) 700-952-1KK00 is presented as a Systeme Helmholz memory module or memory card for Siemens-compatible PLC control systems. Public distributor records identify the 700-952-1KK00 as a 1 MByte RAM module, while another public catalog reference describes the same order code as a 1 MByte EPROM long memory module. Because the memory technology appears differently in public records, the supplied unit should be verified as RAM or EPROM against the module label, original CPU manual and PLC backup record.

Features

The Helmholz 700 family covers Simatic-compatible automation components, including I/O modules, communication modules and memory products for existing Siemens PLC installations. The 700-952-1KK00 record lists memory capacity 1 MByte. Public product images show a slender plug-in memory module intended for installation into a PLC CPU or memory slot.

Classic Automation lists the unit as used or refurbished and gives package dimensions 3.0 in × 1.0 in × 4.0 in, equivalent 7.6 cm × 2.5 cm × 10.2 cm, and tariff code 8536490065. Filkab describes the same part number as Fl EPROM long 1 MByte. The discrepancy between RAM and EPROM records means the module's storage type, battery requirement, program retention, erasing method, compatible CPU series and memory slot must be checked before replacement.

Principle

A PLC memory module stores user program, data, parameters or configuration data used by the PLC CPU. A RAM memory module typically provides fast read and write operation and may require battery or backup power to retain memory; an EPROM module typically stores a fixed program or parameter set and retains data without battery, but requires programming or erasing equipment for changes. The memory module is inserted into the compatible CPU or memory slot so the PLC can load or retain the control program during operation.

Replacement should identify the exact CPU model, memory slot, required memory capacity, memory technology, battery or backup condition, program version, data block, parameter set and configuration backup. Because public records disagree on RAM versus EPROM, the replacement must not be assumed compatible from the order number alone. Program upload or download, memory formatting, battery replacement and PLC commissioning should follow the original Siemens or Helmholz documentation and site backup procedure.

Applications

HELMHOZ 700-952-1KK00 is retained as a legacy PLC memory spare for existing Helmholz or Siemens-compatible control systems in industrial machines, production lines, packaging equipment, material handling, process panels, machine tools, conveyors, pumping or fan control, utilities and general automation. It supports repair or refurbishment of existing PLC CPU memory rather than new system design. In legacy installations, the module serves as a direct replacement memory spare only when the CPU model, slot, capacity, memory type, program version and backup configuration match the original unit.
