Configured as a 32-channel dry contact relay-based interface, this single-slot module switches external control circuits for solenoids, interlock relays, and status indicator fields. It executes output state transitions natively at the subrack tier to maintain system interlocks parallel to master processor execution 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\u003eADM52T-2 (ADT32)\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\u003e1.36 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e30 mm x 130 mm x 150 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDigital Contact Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Density\u003c\/td\u003e\n\u003ctd\u003e32 independent discrete contact outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Contact Type\u003c\/td\u003e\n\u003ctd\u003eDry contact relay-based outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Operational Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperational Voltage Range\u003c\/td\u003e\n\u003ctd\u003e12 VDC to 30 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Barrier\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;=500 VDC between channels and internal system logic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHardware Response Time\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;10 ms output signal state actuation transition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eYokogawa CENTUM CS\/VP and ProSafe-RS architectures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control \u0026amp; SIS Instrumentation Architecture\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFail-Safe State Execution and Safety Automation:\u003c\/strong\u003e The ADM52T-2 handles critical binary switching paths where deterministic output responses are mandatory for process protection loops. When deployed within a ProSafe-RS Safety Instrumented System (SIS), the relay driver logic executes hard-wired de-energization scripts within its \u0026lt;10 ms hardware response window, forcing connected emergency shutdown (ESD) solenoids into their defined fail-safe states upon logic trip conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel-to-Channel Isolation and Fault-Tolerant Mapping:\u003c\/strong\u003e The module contains optical and galvanic separation layers supplying \u0026gt;=500 VDC of isolation between the external 12-30 VDC field loop circuits and the internal backplane logic matrix. This hardware barrier isolates high-voltage electrical field anomalies, switching transients, or common-mode ground loop currents to their individual terminal paths, preventing field-tier faults from corrupting the master DCS control bus.\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 external 24 VDC control loop encounters a short circuit at the ADM52T-2 terminal pin?\u003c\/p\u003e\n\u003cp\u003eA: The module's internal system logic remains operational due to the \u0026gt;=500 VDC galvanic isolation boundary. The overcurrent condition remains isolated to that specific field loop, preventing the electrical spike from compromising the parallel operation of the remaining 31 digital output channels.\u003c\/p\u003e\n\u003cp\u003eQ: Can this 1.36 kg digital output module be extracted from the FIO node while the ProSafe-RS safety loop is actively monitoring a live process?\u003c\/p\u003e\n\u003cp\u003eA: No. Extracting a safety-critical output module under power will instantly interrupt the dry contact relay loops, dropping current to all 32 channels. This will cause downstream solenoids or actuators to de-energize immediately, triggering a process shutdown or safety interlock trip unless the field loops are bypassed at the marshalling panel first.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":47701266432190,"sku":"ADM52T-2 ADT32","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-16_10-05-04_f3511551-c4f3-4b90-9756-a21acab5766f.png?v=1782208346","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-adm52t-2-adt32-digital-output-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
