Configured as a pressure-clamp type interface, this module establishes direct electrical connection between field instrumentation and intrinsically safe I\/O modules. It manages signal routing for dual-redundant analog input loops natively at the termination tier, isolating measurement lines parallel to master control system backplane communication cycles.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\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\u003eATSA3D-0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.30 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e65.6 mm x 72 mm x 114 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eTerminal Block Module (Pressure Clamp Type)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible I\/O Module\u003c\/td\u003e\n\u003ctd\u003eASI133 Analog Input Module (8-channel, isolated)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Count\u003c\/td\u003e\n\u003ctd\u003e8-channel analog input, dual-redundant configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication Profile\u003c\/td\u003e\n\u003ctd\u003eFor I\/O modules with built-in barrier (FIO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Range\u003c\/td\u003e\n\u003ctd\u003e5% to 95% RH, non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironmental Standard\u003c\/td\u003e\n\u003ctd\u003eISA S71.04 class G3 corrosive atmospheres\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExplosion Protection\u003c\/td\u003e\n\u003ctd\u003eSupports intrinsically safe installations with approved barrier modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control \u0026amp; DCS Instrumentation Architecture\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-20 mA HART Loop Protocol and Barrier Integration:\u003c\/strong\u003e The ATSA3D-0 routes 4-20 mA analog input currents directly from hazardous-area instruments to the ASI133 isolated input module. The terminal board layout maintains mechanical trace separation to support intrinsically safe circuit parameters, allowing low-voltage signal modulation to pass through built-in FIO safety barriers without dropping loop voltage thresholds or altering loop impedance tolerances.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel-to-Channel Isolation and Redundant Tracking:\u003c\/strong\u003e The hardware interface is wired to support dual-redundant 8-channel topologies, splitting analog signals across redundant input paths. This layout uses physical galvanic barriers between circuits to stop common-mode noise and ground loop currents from migrating across channels, keeping measurement loops stable if a single terminal path faults.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What specific hardware behaviors manifest if an analog field line encounters an electrical short within the ATSA3D-0 pressure clamp?\u003c\/p\u003e\n\u003cp\u003eA: The high-density termination layout isolates the fault path. The paired ASI133 safety barrier limits loop current to non-incendive levels, while the dual-redundant circuit architecture automatically maintains signal tracking on the parallel backup channel without dropping the DCS process control loop.\u003c\/p\u003e\n\u003cp\u003eQ: Can this 0.30 kg pressure-clamp terminal block be extracted from its cabinet mounting rail while the 4-20 mA loop is actively carrying live current?\u003c\/p\u003e\n\u003cp\u003eA: No. Removing field terminal wiring or disconnecting the block interface while loops are live in a hazardous location can generate an inductive spark. Loop power must be isolated externally or the atmosphere verified as non-hazardous prior to breaking any physical pressure-clamp connections.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":47699743899838,"sku":"ATSA3D-0","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-05-14_10-46-53_bfe70aa3-59d7-4d0a-9ebf-dedda9c0c40e.png?v=1782208146","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-atsa3d-0-terminal-block-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
