The module accepts high level voltage and current signals through 16 independent input channels. The 0 to 20.5 mA current input range uses an internal 250 ohm conversion resistor for analog signal conditioning.\u003c\/p\u003e\n\u003cp\u003eThe module provides channel measurement resolution through a 16-bit analog-to-digital conversion process. Voltage input impedance above 1.0 Mohm minimizes loading effects on connected field devices, while the nominal 249 ohm current input impedance maintains standard industrial analog loop characteristics.\u003c\/p\u003e\n\u003cp\u003eFor process instrumentation applications, channel-to-channel isolation and signal conditioning functions support separation between field wiring and system electronics. Analog loop integration can be combined with standard 4-20 mA HART field device interfaces when external HART communication components are provided within the control architecture.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the TC-IAH161 support direct 4-20 mA signal measurement?\u003cbr\u003eA: The module supports a 0 to 20.5 mA input range through an internal 250 ohm resistor, allowing measurement of standard current loop signals including 4-20 mA ranges.\u003c\/p\u003e\n\u003cp\u003eQ: What type of terminal connection is required for the TC-IAH161?\u003cbr\u003eA: The module connects through a Honeywell TC-TBCH 36-position terminal block for field signal termination.\u003c\/p\u003e\n\u003cp\u003eQ: What is the module publish rate for analog input data?\u003cbr\u003eA: The TC-IAH161 publishes input data at a rate of 250 msec.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the TC-IAH161 in the designated Honeywell I\/O rack or termination assembly according to the applicable system hardware configuration.\u003c\/p\u003e\n\u003cp\u003eUse shielded instrumentation cable for analog signal wiring where required by the installation environment. Connect cable shields according to the site grounding standard to reduce electromagnetic interference and maintain signal integrity.\u003c\/p\u003e\n\u003cp\u003eSeparate analog signal wiring from high-voltage power cables and switching circuits to minimize induced noise. Verify field device signal polarity, voltage range selection, and current loop wiring before applying system power.\u003c\/p\u003e\n\u003cp\u003eEnsure the TC-TBCH terminal block connections are fully seated and that all field wiring terminals are mechanically secured before commissioning.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":44345697108056,"sku":"TC-IAH16I","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/TC-IAH16I-3.jpg?v=1783500622","url":"https:\/\/www.industriaxplc.com\/products\/tc-iah161-honeywell-high-level-analog","provider":"IndustriaX Limited","version":"1.0","type":"link"}
