The hardware establishes long-distance master-to-slave communication links by transforming electrical bus frames into optical pulses for transmission over fiber optic infrastructure. It manages physical-layer data framing, ensures optical power balance across distributed architectures, and coordinates structural backplane routing sequences without altering processor cycle timings.\u003c\/p\u003e\n\u003ch3\u003eSuffix Breakdown \u0026amp; Model Matrix\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANT401\u003c\/strong\u003e: Base model code for the Optical ESB Bus Repeater Master Module platform architecture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e-5\u003c\/strong\u003e: Standard module type variant configured with no explosion protection barriers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0\u003c\/strong\u003e: Basic functionality configuration profile identifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e\/CU1T\u003c\/strong\u003e: Connector unit sub-assembly featuring an integrated physical terminator for the electrical ESB bus.\u003c\/li\u003e\n\u003c\/ul\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\u003eANT401-50\/CU1T\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\u003e0.3 kg (Net module weight; gross shipping allocation 2.0 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e32.8 x 142.5 x 130 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e2.5 W maximum (5 VDC internal logic rail draw at 0.5 A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransmission Medium\u003c\/td\u003e\n\u003ctd\u003eDual-core fiber optic cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Distance\u003c\/td\u003e\n\u003ctd\u003e5 km nominal (extendable to 10 km under specific Vnet\/IP specifications)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Conversion\u003c\/td\u003e\n\u003ctd\u003eBidirectional Electrical-to-Optical (E\/O) array\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Topology\u003c\/td\u003e\n\u003ctd\u003eStar or chain bus configurations (maximum 2 stages)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStyle Code\u003c\/td\u003e\n\u003ctd\u003eStyle S1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control Loops and Analog Field Configurations\u003c\/h3\u003e\n\u003cp\u003eThe optical transmission unit separates localized electrical backplane tracks from distributed field channels operating the 4-20 mA HART loop protocol. By converting communications to optical media, the module establishes complete galvanic isolation, neutralizing ground potential differentials and blocking electromagnetic interference (EMI) generated by field-side surges. This prevention of high-frequency signal bleed preserves electrical reference baselines for adjacent I\/O modules executing analog conversions, cold junction compensation (CJC), or high-density channel-to-channel isolation.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the physical network segment affected if the integrated \/CU1T connector unit is detached while the system is live?\u003c\/p\u003e\n\u003cp\u003eA: Detaching the \/CU1T connector drops the required electrical termination across the local bus line. This causes instant impedance mismatches, signal reflections, and data frame corruption, resulting in an active bus fault that will interrupt adjacent processing slots.\u003c\/p\u003e\n\u003cp\u003eQ: Does the ANT401-50\/CU1T master module support direct connection to field transmitters or sensors?\u003c\/p\u003e\n\u003cp\u003eA: No. This hardware functions strictly as a bus repeater subsystem component. It must be paired with a compatible downstream optical slave repeater module to decode the optical signals back into standard electrical backplane bus logic before interfacing with I\/O cards.\u003c\/p\u003e\n\u003cp\u003eQ: Is hot-swap module extraction permitted within an active, synchronized duplex rack configuration?\u003c\/p\u003e\n\u003cp\u003eA: No. The underlying Centum VP hardware frame architecture does not support live hot-swap execution for this class of interface repeater. The system and rack power must be completely isolated before extracting or inserting the module to prevent electrical damage.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompletely isolate the main power infrastructure feeding the controller rack before inserting or removing the master module.\u003c\/li\u003e\n\u003cli\u003eMaintain the manufacturer-specified minimum bending radius for all dual-core fiber optic lines to prevent micro-fractures and optical signal attenuation.\u003c\/li\u003e\n\u003cli\u003eVerify that the integrated \/CU1T connector unit is firmly seated and locked to provide correct line termination for the local electrical segment.\u003c\/li\u003e\n\u003cli\u003eRoute all fiber optic runs through dedicated conduits, isolated from high-voltage motor starters and high-current AC cabling networks.\u003c\/li\u003e\n\u003cli\u003eEnsure all optical ports and cable connectors are fully cleaned using industrial-grade lint-free wipes before mating the physical interfaces.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44220929212515,"sku":"ANT401-50\/CU1T","price":360.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/333_183305a2-0605-4cbf-846d-7c67ff9873f1.jpg?v=1780044622","url":"https:\/\/www.autocontrolglobal.com\/products\/ant401-50-cu1t-yokogawa-optical-repeater-module-new-original-stock","provider":"AutoControl Global","version":"1.0","type":"link"}
