Occupying a double-slot chassis width, it bridges data exchange between Honeywell controllers and external field hardware such as PLCs, drives, and instrumentation. The \u003cstrong\u003eTK-MUX021\u003c\/strong\u003e features factory conformal coating, providing physical protection against moisture and corrosive airborne contaminants.\u003c\/p\u003e\n\u003ch3\u003eSerial Communication and FTA Integration\u003c\/h3\u003e\n\u003cp\u003eThe module provides 2 communication channels, each dedicated to a Field Termination Assembly (FTA). Depending on the connected FTA, physical signal levels are selectable between EIA RS-232D and EIA RS-422\/485D with communication speeds up to 19.2 kbps per channel. It supports industrial protocol integration via specialized FTAs, including the MU-TSIM12 for Modbus and the MU-TSIA12 for Allen-Bradley DF1 networks.\u003c\/p\u003e\n\u003ch3\u003eHardware Interface and Power Requirements\u003c\/h3\u003e\n\u003cp\u003eA single controller supports up to 3 serial interface modules, drawing power via a TC-KSM003 power adapter cable connected to either a 24 VDC supply adapter (TC-SMPD01) or an 85–265 VAC supply adapter (TC-SMPC01). Designed for demanding mechanical environments, the unit exhibits a maximum power dissipation of 10 W, withstands operating shock up to 30 g peak (11 ms duration), and meets 5 g vibration resistance from 10 to 50 Hz.\u003c\/p\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-MUX021\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e51404391-375\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\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eSerial Interface Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Family\u003c\/td\u003e\n\u003ctd\u003eExperion LS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Configuration\u003c\/td\u003e\n\u003ctd\u003eDual-channel, double-slot width\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Ports\u003c\/td\u003e\n\u003ctd\u003e2 ports (1 per FTA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Interfaces\u003c\/td\u003e\n\u003ctd\u003eEIA RS-232D, EIA RS-422\/485D (selectable by FTA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Data Rate\u003c\/td\u003e\n\u003ctd\u003e19.2 kbps per FTA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible FTAs\u003c\/td\u003e\n\u003ctd\u003eMU-TSIM12 (Modbus), MU-TSIA12 (Allen-Bradley DF1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eController Capacity\u003c\/td\u003e\n\u003ctd\u003eMax. 3 modules per controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Adapters\u003c\/td\u003e\n\u003ctd\u003eTC-SMPD01 (24 VDC) or TC-SMPC01 (85–265 VAC) via TC-KSM003 cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Dissipation\u003c\/td\u003e\n\u003ctd\u003eMax. 10 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConformal Coating\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShock \u0026amp; Vibration\u003c\/td\u003e\n\u003ctd\u003eShock: 30 g peak (11 ms); Vibration: 5 g, 10–50 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (L × W × H)\u003c\/td\u003e\n\u003ctd\u003e108 mm × 87 mm × 78 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.91 kg (2.0 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eCE, TUV, UL508, CSA\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: What is the difference between the Honeywell TK-MUX021 and TC-MUX021 modules?\u003c\/p\u003e\n\u003cp\u003eA: The TK-MUX021 is the conformally coated version of the standard TC-MUX021 module, designed to protect electronics from harsh industrial atmospheres.\u003c\/p\u003e\n\u003cp\u003eQ: Which protocols and physical interfaces are supported by the TK-MUX021?\u003c\/p\u003e\n\u003cp\u003eA: It supports RS-232D and RS-422\/485D interfaces running up to 19.2 kbps per port, interfacing with Modbus (via MU-TSIM12 FTA) or Allen-Bradley DF1 (via MU-TSIA12 FTA).\u003c\/p\u003e\n\u003cp\u003eQ: How is external power supplied to the TK-MUX021 serial interface module?\u003c\/p\u003e\n\u003cp\u003eA: Power connects via a TC-KSM003 adapter cable using either a 24 VDC power supply (TC-SMPD01) or an 85–265 VAC power supply (TC-SMPC01).\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":43796192919651,"sku":"TK-MUX021 51404391-375","price":320.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/475.2_c605448b-344f-4c07-a4ae-61d05f31364c.jpg?v=1761616021","url":"https:\/\/www.autocontrolglobal.com\/products\/honeywell-tk-mux021-51404391-375-serial-interface-module","provider":"AutoControl Global","version":"1.0","type":"link"}
