The assembly establishes a direct physical interconnect between system I\/O modules and field terminal boards. It conducts parallel control and measurement signals via dual 40-pin connectors across cable lengths up to 20 meters without signal attenuation.\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\u003eKS1-20\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\u003e3.50 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eCable length 20 meters (65.6 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePassive (0 W)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable Assembly Type\u003c\/td\u003e\n\u003ctd\u003eMulti-core system interconnect cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTermination 1\u003c\/td\u003e\n\u003ctd\u003e40-pin male connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTermination 2\u003c\/td\u003e\n\u003ctd\u003e40-pin male connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Cable Length\u003c\/td\u003e\n\u003ctd\u003e20 meters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eYokogawa DCS I\/O cards and terminal boards\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 and Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe Yokogawa KS1-20 system cable incorporates twisted-pair internal conductors enclosed within an overall braided shield to maintain channel-to-channel isolation across all 40 signal pins. This construction preserves signal integrity during multi-channel 4-20 mA analog output and HART protocol digital communication, preventing cross-talk between adjacent loops. The grounded cable shield suppresses high-frequency electromagnetic interference (EMI) in industrial control cabinets, maintaining steady noise-free data paths between DCS modules and field wiring termination units.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the primary physical terminations on the Yokogawa KS1-20 cable?\u003c\/p\u003e\n\u003cp\u003eA: The cable features standard 40-pin industrial connectors on both ends designed for direct mating with Yokogawa DCS I\/O cards and terminal boards.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum physical cable length represented by the -20 suffix?\u003c\/p\u003e\n\u003cp\u003eA: The -20 suffix code specifies an overall cable assembly length of 20 meters.\u003c\/p\u003e\n\u003cp\u003eQ: Can the KS1-20 cable be disconnected while the DCS I\/O module is energized?\u003c\/p\u003e\n\u003cp\u003eA: Signal-level hot-swapping is permissible provided field loop power is de-energized or system field interlocks are configured prior to disconnection.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect both 40-pin connectors for bent pins, dust, or locking clip damage prior to insertion.\u003c\/li\u003e\n\u003cli\u003eAlign the keyway of the 40-pin connector with the header on the Yokogawa DCS I\/O card and push straight in until locked.\u003c\/li\u003e\n\u003cli\u003eAttach the cable shield grounding drain wire to the designated rack cabinet ground bar to ensure continuous EMI shielding.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum cable bend radius of 4.0 inches (100 mm) along the 20-meter cable run to prevent conductor strain.\u003c\/li\u003e\n\u003cli\u003eAvoid running the signal cable parallel to high-voltage AC lines or variable frequency drive power conductors in cabinet wire ducts.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":48708405854398,"sku":"KS1-20","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-08-13_16-59-19_1200x1200_59d91326-04fa-43e1-bcc2-e5f0218744b0.jpg?v=1786615084","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-ks1-20-signal-cable","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
