Utilizing dual-redundant internal signal paths, the block maintains physical circuit continuity even if one internal signal line suffers an open circuit. The spring-loaded pressure clamp terminals provide high vibration resistance and prevent wire loosening in harsh plant environments, enabling continuous transmission for 4-20 mA HART loop protocol transmitters while supporting isolated channel signal routing to the host DCS.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What specific Yokogawa FIO I\/O modules are compatible with the ATA4D-00 S2 terminal block?\u003c\/p\u003e\n\u003cp\u003eA: The ATA4D-00 S2 is designed to pair directly with 16-channel analog input modules within the FIO system, such as the AAI141 and AAI143 series.\u003c\/p\u003e\n\u003cp\u003eQ: What type of field wire connection mechanism is utilized on the ATA4D-00 S2?\u003c\/p\u003e\n\u003cp\u003eA: The module uses a screw-less pressure clamp terminal mechanism, which speeds up field wiring and ensures resistance against vibration-induced wire disconnection.\u003c\/p\u003e\n\u003cp\u003eQ: How does the dual-redundant feature of the ATA4D-00 S2 enhance system availability?\u003c\/p\u003e\n\u003cp\u003eA: The terminal block incorporates dual internal wiring paths, enabling continuous signal transmission between field transmitters and the host I\/O module if a single connection path is compromised.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the host FIO module rack power and field transmitter loops are isolated before connecting or servicing field wiring.\u003c\/li\u003e\n\u003cli\u003eMount the ATA4D-00 S2 assembly onto the dedicated I\/O interface base, verifying that the retaining latches snap firmly into place.\u003c\/li\u003e\n\u003cli\u003eStrip field wire insulation to the recommended strip length without nicking the copper conductors.\u003c\/li\u003e\n\u003cli\u003eInsert a standard flat-blade screwdriver into the pressure clamp release slot to open the spring terminal, insert the wire lead fully, and release the clamp.\u003c\/li\u003e\n\u003cli\u003eSecure all field cable shields to the system protective earth ground bar to ensure proper noise immunity and suppress electromagnetic interference across analog input channels.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":52626129846552,"sku":"ATA4D-00 S2","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/ATA4D-00S2_Cocoai.jpg?v=1788773539","url":"https:\/\/www.innoplcsync.com\/products\/yokogawa-ata4d-00-s2-dual-redundant-terminal-block","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
