It accepts sine-wave inputs from 1–20 V peak up to 30 kHz or square-wave inputs from 10–12 V peak up to 100 kHz (50% duty cycle; up to 110 kHz if the square wave duty is limited to 25%), with the input signal optically isolated from the output. The unit includes an isolated +12 VDC power supply rated at 100 mA to power encoders or sensors, and the 0–12 VDC output can be used for tach feedback or as a speed reference. It is designed for Carotron non-regenerative and regenerative motor controls and may be compatible with other drives if the feedback is scaled to the nominal 12 V output range. Multi-turn potentiometers adjust OFFSET, GAIN, and BIAS, and there are terminals for an external TRIM pot when used as a speed reference, plus a built‑in TRIM RANGE control to limit external adjustments. The converter accepts encoder inputs up to 1024 pulses per revolution on motors with a maximum speed of about 6000 RPM, delivering a proportional analog signal for closed-loop control. For system integration, the card supports standard acceleration\/deceleration control (linear accel\/decel, 1–600 seconds) and provides a +10 VDC reference voltage, with auxiliary +\/-12 V rails available for additional circuitry. Its physical footprint is 5.5 × 4.25 × 2.87 inches, designed for mounting in Carotron system interconnects. \u003c\/p\u003e\u003c\/div\u003e","brand":"CAROTRON","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677720117550,"sku":null,"price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_bef30202-2cab-4d19-888a-d313aa4c7825.jpg?v=1769566918","url":"https:\/\/plgautomation.com\/products\/carotron-c11451-000-pc-converter-board-115-230-vac","provider":"PLG Automation ","version":"1.0","type":"link"}
