The unit accepts analog and discrete signals directly from field transmitters, processing feedback loops autonomously to regulate final control elements. Designed for panel mounting, the internal microprocessor handles arithmetic logic, cascade control structures, and high-precision signal processing independently from host SCADA networks.\u003c\/p\u003e\n\u003ch3\u003eSuffix Breakdown \u0026amp; Model Matrix\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eSuffix Code\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eFunctional Description\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eYS170\u003c\/td\u003e\n\u003ctd\u003eBase Model\u003c\/td\u003e\n\u003ctd\u003eSingle-Loop Programmable Controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e-012\u003c\/td\u003e\n\u003ctd\u003eConfiguration Variant\u003c\/td\u003e\n\u003ctd\u003eSpecific I\/O allocation and software execution options\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eS3\u003c\/td\u003e\n\u003ctd\u003eStyle Revision\u003c\/td\u003e\n\u003ctd\u003eStyle S3 hardware design and motherboard revision\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\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\u003eYS170-012 S3\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\u003e1.6 kg net (2.2 kg shipping weight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e70 mm W x 145 mm H x 293 mm D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to +50 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e100-120 VAC (50\/60 Hz) \/ 24-120 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl Loops\u003c\/td\u003e\n\u003ctd\u003eSingle-loop PID, ratio, cascade, and feedforward control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Processing\u003c\/td\u003e\n\u003ctd\u003eConfigurable analog I\/O and discrete I\/O channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eOptional RS-485 Modbus serial communication interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Profile\u003c\/td\u003e\n\u003ctd\u003ePanel mount cutout \/ rack frame mounting\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol \u0026amp; Channel-to-Channel Isolation Integration\u003c\/h3\u003e\n\u003cp\u003eThe YS170-012 S3 controller incorporates galvanically isolated input and output stages to preserve signal integrity across noisy industrial environments. Internal channel-to-channel isolation prevents ground loop formation when interfacing with 4-20 mA HART loop protocol transmitters and analog positioning devices. Dedicated cold junction compensation (CJC) algorithms run internally to linearize temperature sensor inputs, ensuring accurate loop processing without introducing high-frequency electrical noise or offset drift back into the main DCS network backplane.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the YS170-012 S3 maintain loop execution during a central DCS communication failure?\u003c\/p\u003e\n\u003cp\u003eA: The controller runs its firmware logic, PID calculations, and output switching locally. If RS-485 network communication drops, the module automatically continues executing its assigned single-loop control routine without output freezing or dropping to fail-safe zero unless pre-programmed to do so.\u003c\/p\u003e\n\u003cp\u003eQ: Can the internal control strategy and parameter setpoints be modified without physical wiring changes?\u003c\/p\u003e\n\u003cp\u003eA: Yes. All internal block configurations, loop algorithms, and I\/O assignments are modified via software through the front programming port or over the optional Modbus RS-485 interface without removing terminal wiring.\u003c\/p\u003e\n\u003cp\u003eQ: What power source is required to operate the YS170-012 S3 module?\u003c\/p\u003e\n\u003cp\u003eA: The module operates on dual-range power inputs supporting 100-120 VAC at 50\/60 Hz or 24-120 VDC auxiliary supply lines.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Cutout Grounding:\u003c\/strong\u003e Ensure the metal panel frame surrounding the cutout makes a clean, unpainted conductive connection to functional earth (FE) to drain electrostatic build-up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnalog Signal Routing:\u003c\/strong\u003e Route 4-20 mA analog input and output cables in dedicated instrument trays separate from high-voltage AC power wiring by at least 200 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Termination:\u003c\/strong\u003e Connect cable shields for analog I\/O at a single grounding point near the controller chassis to eliminate field ground loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Wiring Tension:\u003c\/strong\u003e Tighten terminal screw connections to the manufacturer recommended torque limits prior to applying 100-120 VAC line power.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43796429635674,"sku":"YS170-012 S3","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/755..jpg?v=1786069304","url":"https:\/\/www.spareoil.com\/products\/programmable-loop-controller-yokogawa-ys170-012-s3-ys100","provider":"SpareOil Automation","version":"1.0","type":"link"}
