Digital telemetry data pass through via 4-20 mA HART loop protocol superimposed over standard analog current signals. The module maintains an input resistance between 400 ohm and 1000 ohm during power-on operation, switching to a high-impedance state exceeding 500 k-ohm during power-off conditions to prevent circuit loading on adjacent field instrumentation loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the input resistance behavior of the AAI141-H00 S2 during powered and unpowered states?\u003c\/p\u003e\n\u003cp\u003eA: When powered on, the module maintains an input resistance between 400 ohm (at 20 mA) and 1000 ohm (at 4 mA). When powered off, the input resistance increases to 500 k-ohm or higher.\u003c\/p\u003e\n\u003cp\u003eQ: Does the AAI141-H00 S2 provide loop power to external field transmitters?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module supplies integrated transmitter power rated at 14.8 VDC or higher at 20 mA, and 26.4 VDC or lower at 0 mA.\u003c\/p\u003e\n\u003cp\u003eQ: What connection hardware options are supported for external signal wiring?\u003c\/p\u003e\n\u003cp\u003eA: External wiring interfaces with pressure clamp terminals, KS cables, or MIL connector cables depending on the termination block assembly used.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eDe-energize backplane rack power prior to inserting or removing the AAI141-H00 S2 module. Observe electrostatic discharge (ESD) safety procedures by wearing a grounded wrist strap during card handling. Insert the module into the CENTUM I\/O slot until the backplane connectors seat completely, then tighten top and bottom retaining screws to establish frame ground continuity. Ensure that common-mode voltage across signal channels remains within +\/-1 VDC. Connect field wiring using pressure clamp terminal blocks, KS cables, or MIL connector cables. Route analog signal lines in shielded twisted-pair cables and bond the shield wire at a single earth ground termination point inside the cabinet panel.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":53280315539765,"sku":"AAI141-H00 S2","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/AAI141-H00K4A00_987e2ebe-7fc8-4fca-a692-db2c1913d546.png?v=1786669904","url":"https:\/\/www.5gplc.com\/products\/yokogawa-aai141-h00-s2-centum-analog-input-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
