Featuring 64 isolated single-ended channels, this module accepts both voltage (0-5 VDC) and current (0-20 mA) inputs, offering programmable 12-bit or 14-bit resolution and a rapid channel update rate of 10 ms.\u003c\/p\u003e\n\u003ch3\u003eSignal Conditioning and Performance\u003c\/h3\u003e\n\u003cp\u003eThe module supports a 0-5 VDC input voltage range and a 0-20 mA current range when utilized with external 250 ohm shunt resistors, both providing a +6% overrange margin. It achieves an accuracy of \u0026lt; 0.15% of full scale range across operating temperatures from 0 deg C to 60 deg C. Advanced filtering provides normal mode noise rejection (-3 dB @ 8 Hz, -17 dB @ 60 Hz, -23 dB @ 120 Hz) to maintain high signal fidelity in noisy industrial environments.\u003c\/p\u003e\n\u003ch3\u003eChannel Isolation and Protection\u003c\/h3\u003e\n\u003cp\u003eEach channel is galvanically isolated to prevent earth loops and protect system electronics from field disturbance. Built-in input overrange protection guards internal components against voltage spikes, while a continuous common mode voltage tolerance of 150 VDC \/ 115 VAC ensures steady operation under adverse electrical conditions.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e3720\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eInvensys (Triconex)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAnalog Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Structure\u003c\/td\u003e\n\u003ctd\u003e64 channels, single-ended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e0-5 VDC (+6% overrange)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Current Range\u003c\/td\u003e\n\u003ctd\u003e0-20 mA (+6% overrange) with 250 ohm shunt resistor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e12 bits or 14 bits (programmable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUpdate Rate\u003c\/td\u003e\n\u003ctd\u003e10 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 0.15% of FSR (0 deg C to 60 deg C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance (Load)\u003c\/td\u003e\n\u003ctd\u003e10 Mohm min (DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower-Off Resistance\u003c\/td\u003e\n\u003ctd\u003e140 kohm typical (DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLeg-to-Leg Isolation\u003c\/td\u003e\n\u003ctd\u003e420 kohm typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Mode Range\u003c\/td\u003e\n\u003ctd\u003e150 VDC \/ 115 VAC continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNormal Mode Rejection\u003c\/td\u003e\n\u003ctd\u003e-3 dB @ 8 Hz, -17 dB @ 60 Hz, -23 dB @ 120 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverrange Protection\u003c\/td\u003e\n\u003ctd\u003eBuilt-in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: How does the Triconex 3720 module accommodate 0-20 mA current loops?\u003c\/p\u003e\n\u003cp\u003eA: The module measures 0-20 mA current signals by using external 250 ohm shunt resistors to convert the current into an equivalent voltage signal.\u003c\/p\u003e\n\u003cp\u003eQ: Can the conversion resolution of the 3720 analog input module be adjusted?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module features programmable resolution, allowing configuration for either 12 bits or 14 bits depending on system application requirements.\u003c\/p\u003e\n\u003cp\u003eQ: What is the channel update rate for the 64 input points on the 3720?\u003c\/p\u003e\n\u003cp\u003eA: The module updates all 64 isolated single-ended channels every 10 ms.\u003c\/p\u003e","brand":"Triconex","offers":[{"title":"Default Title","offer_id":67899652079925,"sku":"3720","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/2755-020_Cocoai_de9188d8-2498-406e-8852-124cfba34cd0.png?v=1792647789","url":"https:\/\/www.5gplc.com\/products\/invensys-triconex-3720-analog-input-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
