This memory submodule, also cataloged as 6ES5 375-8LA12 (and variants such as 6ES5-375-8LA12), plugs into the S5 CPU’s memory submodule interface to extend program memory for classic Siemens S5 systems. As part of the S5 memory submodule family, the 6ES5375-8LA12 provides 8 kilobytes of EPROM storage that preserves the control logic across power cycles, supporting field replacement and program transfer in STEP5-era PLC configurations. Installation is performed in the CPU’s dedicated memory submodule slot, and the part is commonly sold by vendors that specialize in vintage Siemens automation hardware for use with compatible S5 CPUs and memory buses.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268488089834,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-6es5-375-8la12-memory-submodule","provider":"GTG Hardware","version":"1.0","type":"link"}
