The 5 V counter input uses RS 422 differential signaling with a 220 ohm terminating resistor and 1.3 V differential input voltage. The 24 V counter input accepts +11 V to +28.8 V for signal \"1\" and -28.8 V to +5 V for signal \"0\" at 9 mA typical input current, with a minimum pulse width of 2.5 us. Potential separation between channels and the backplane bus is provided by optocouplers on digital inputs, digital outputs, and the counter. Isochronous mode is supported for deterministic cycle-synchronized operation. A configuration package is included on CD.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum counting frequency of the FM 350-1?\u003c\/strong\u003e\u003cbr\u003e\nA: 500 kHz for the 5 V RS 422 differential input, and 200 kHz for the 24 V input.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the weight and physical size of the 6ES7350-1AH03-0AE0?\u003c\/strong\u003e\u003cbr\u003e\nA: Approximately 250 g, with dimensions of 40 mm width, 125 mm height, and 120 mm depth.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What front connector does the module require?\u003c\/strong\u003e\u003cbr\u003e\nA: One 20-pin front connector.\u003c\/p\u003e\n\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\n\u003cp\u003eInsert the module into an S7-300 rack and secure with the mounting screws. Wire the 20-pin front connector per the module pin assignment before energizing. Verify supply voltage at 1L+ and 2L+ is within 20.4 V to 28.8 VDC. Route encoder cables separate from high-current power conductors to preserve signal integrity at 500 kHz. Confirm the 5 V encoder supply load does not exceed 300 mA and the 24 V encoder supply load does not exceed 400 mA. Verify the encoder type and signal format match the configured counting mode before commissioning.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":67592292958340,"sku":"6ES7350-1AH03-0AE0","price":154.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/6ES7350-1AH03-0AE0.jpg?v=1790996891","url":"https:\/\/www.etowonauto.com\/pt\/products\/siemens-6es7350-1ah03-0ae0-s7-300-counter-module","provider":"Etowon Auto","version":"1.0","type":"link"}
