Operating on a 24 VDC nominal power supply with an active power consumption of 5 W, the unit establishes bidirectional data conversion across RS-485 serial interfaces and I\/O Link protocols. Featuring an IP20 enclosure rating and a operating frequency response span from 10 kHz to 50 MHz, the module executes multi-device I\/O signal aggregation across a physical temperature range of -20 to +70 deg C.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\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\u003eTK-IOLI01 (Part Number: 51403427-275)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.40 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e7.0 cm x 14.0 cm x 14.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e5 W (Approx.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eRS-485 \/ I\/O Link Protocol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e10 kHz to 50 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eDIN rail or panel mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Platform\u003c\/td\u003e\n\u003ctd\u003eHoneywell Process Automation Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol \u0026amp; Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe TK-IOLI01 module incorporates internal signal filtering and galvanically isolated bus drivers to maintain integrity across RS-485 and field device links. When deployed alongside 4-20 mA HART loop protocol instruments and high-density analog interfaces, the unit enforces strict channel-to-channel isolation parameters. Ground isolation networks within the module suppress common-mode electrical noise and prevent ground loop circulating currents from interfering with high-speed digital communications or degrading analog signal sampling accuracy.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What mounting configurations does the TK-IOLI01 hardware chassis support inside the control cabinet?\u003c\/p\u003e\n\u003cp\u003eA: The module supports direct mechanical snap-on mounting via standard 35 mm DIN rail slots or direct screw installation using panel-mount mounting holes.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module handle signal degradation on the RS-485 serial interface over extended field distances?\u003c\/p\u003e\n\u003cp\u003eA: The unit utilizes differential transceiver circuitry compliant with RS-485 transmission standards to suppress common-mode noise and maintain signal clarity across the 10 kHz to 50 MHz frequency response range.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the TK-IOLI01 assembly vertically on a grounded 35 mm DIN rail or secure it to a flat enclosure backpanel using appropriate screws.\u003c\/li\u003e\n\u003cli\u003eConnect the 24 VDC system power leads to the designated terminal connectors, verifying proper DC line polarity before energizing.\u003c\/li\u003e\n\u003cli\u003eWire the RS-485 serial signal lines using twisted-pair shielded cabling, ensuring signal lines remain isolated from high-voltage AC power conductors.\u003c\/li\u003e\n\u003cli\u003eConnect cable shields directly to the cabinet main earth ground bus bar at a single termination point to ensure proper electromagnetic interference shielding.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53626198229301,"sku":"TK-IOLI01 51403427-275","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/TK-IOLI0151403427-275_Cocoai.png?v=1790060531","url":"https:\/\/www.5gplc.com\/products\/honeywell-tk-ioli01-i-o-link-interface-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
