The CPU 312C integrates 10 digital inputs and 6 digital outputs with a 24 VDC power supply. Two fast counters operate at 10 kHz for technological functions. Bit operations execute in 0.2 us typical, word operations in 0.4 us, fixed point arithmetic in 5 us, and floating point arithmetic in 6 us. Work memory is 32 kbyte and is not expandable; load memory requires a micro memory card with a maximum of 4 Mbyte. Data retention on the MMC is guaranteed for a minimum of 10 years without battery. A total of 1024 blocks (DB, FC, FB) are supported with a maximum size of 16 kbyte per block. The integrated MPI RS 485 interface supports cable lengths up to 50 m without a repeater. Reverse polarity protection is provided on digital inputs but not on digital outputs. Digital outputs are short-circuit protected with a typical response threshold of 1 A and support switching frequencies up to 100 Hz with resistive load, 2.5 kHz for pulse outputs.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the weight and physical size of the 6ES7312-5BE03-0AB0?\u003c\/strong\u003e\u003cbr\u003e\nA: Approximately 409 g, with dimensions of 80 mm width, 125 mm height, and 130 mm depth.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What memory card does the CPU 312C require?\u003c\/strong\u003e\u003cbr\u003e\nA: A micro memory card (MMC) is required.

Verify 24 VDC supply polarity before energizing; digital inputs are reverse polarity protected, digital outputs are not. Insert a micro memory card before downloading the program. Confirm firmware version V2.6 matches the hardware update in STEP 7 V5.3 SP2 or higher. Route shielded encoder cables for technological functions to a maximum of 100 m; unshielded cables are not permitted for counter inputs. Verify MPI cable length does not exceed 50 m without a repeater. External power supply lines require a miniature circuit breaker type C at minimum 2 A or type B at minimum 4 A.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":67601929306244,"sku":"6ES7312-5BE03-0AB0","price":156.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/6ES7312-5BE03-0AB0.jpg?v=1791084532","url":"https:\/\/www.etowonauto.com\/kk\/products\/siemens-6es7312-5be03-0ab0-cpu-312c-compact","provider":"Etowon Auto","version":"1.0","type":"link"}
