MeloAuto-Trusted PLC & DCS Parts Supplier
The Siemens 6AV1202-0BA00 expands the volatile memory capacity of SIMATIC HMI panels. You can plug this module directly into the memory slot on compatible operator panels. It stores recipe data and screen buffers during panel operation. This module suits applications requiring temporary data storage for batch processes.
Technical Specifications and Internal Design
This RAM memory module measures 55 mm in height. Its width reaches 25 mm, and the depth equals 8 mm. The Siemens 6AV1202-0BA00 weighs approximately 0.02 kilograms. A single small PCB holds all memory ICs and interface logic. The module stores data using dynamic RAM technology. It contains no energy storage devices or backup batteries. Data will clear completely when the panel loses power. One 72-pin edge connector interfaces with the HMI panel’s memory slot.

Memory Capacity and Performance
The Siemens 6AV1202-0BA00 provides 512 KB of volatile RAM storage. This capacity holds approximately 1000 recipe records or screen pages. The module supports read and write access times of 70 nanoseconds. Consequently, this speed ensures smooth screen transitions and fast data logging. Dynamic RAM requires periodic refresh cycles from the host panel. The module consumes only 50 mA from the panel’s 5 V supply.
Installation and Practical Usage Guidelines
You must insert this module firmly into the HMI panel’s expansion slot. Transitioning to operation, the panel will detect the module automatically. Do not remove the module while the panel remains powered on. For data persistence, save critical recipe data to a memory card regularly. The module fits OP3, OP7, and OP17 series HMI panels. The operating temperature range spans from 0°C to 50°C reliably.
