Designed to maintain high measurement fidelity in DCS environments, the module incorporates channel-to-channel isolation and low-pass filtering to attenuate high-frequency noise and common-mode voltage interference. The conditioned process variable is serialized and transmitted over the internal backplane bus at communications rates up to 1 Mbps.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What power input tolerance is permitted for the CT5-TJ*A module?\u003c\/p\u003e\n\u003cp\u003eA: The module operates on a nominal supply of 24 VDC with an allowable voltage input tolerance of +\/-10%.\u003c\/p\u003e\n\u003cp\u003eQ: What sensor types are compatible with the CT5-TJ*A input channels?\u003c\/p\u003e\n\u003cp\u003eA: The module is hardware-calibrated specifically for Type J thermocouple inputs across a millivolt conversion range of 0 to 180 deg C.\u003c\/p\u003e\n\u003cp\u003eQ: Does the CT5-TJ*A require external cold junction reference hardware?\u003c\/p\u003e\n\u003cp\u003eA: No, the module includes internal cold junction compensation to compensate for local terminal block temperature variations automatically.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eESD Protection:\u003c\/strong\u003e Handle the module card using an anti-static wrist strap connected to cabinet ground prior to removing it from protective packaging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCabinet Mounting:\u003c\/strong\u003e Slide the module assembly into the designated Yokogawa DCS I\/O slot guide until the backplane connector fully seats, then tighten retaining screws.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermocouple Wiring:\u003c\/strong\u003e Utilize extension-grade Type J thermocouple extension wire and maintain correct polarity connections at the terminal block.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Termination:\u003c\/strong\u003e Earth overall cable shielding at a single point on the enclosure instrument grounding bar to suppress electromagnetic interference.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":53312656507189,"sku":"CT5-TJ*A","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/CT5-TJA.png?v=1786947687","url":"https:\/\/www.5gplc.com\/products\/ct5-tj-a-yokogawa-thermocouple-input-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
