CAN Bus Nrog 120 Ohm Terminal Resistance

High-Speed ​​CAN Termination resistor

Tsawg-Speed ​​CAN Termination resistor

Fault-Tolerant CAN Termination resistor

Qhov no CAN tsheb npav txiav tawm resistor (120 Ohm) muaj ib tug 9-pin D-Sub connector (txiv neej), ib tug 9-pin D-Sub socket (poj niam).

Lub luag haujlwm ntawm kev txiav cov resistors

(1) Cov lus qhia dav dav: Lub davhlau ya nyob twg tsis muaj zog yog ua kom tsis muaj zog ntawm cov teeb liab cuam tshuam hauv kev sib txuas lus cable.

(2) Lub teeb liab kis tau tus mob muaj nws cov yam ntxwv impedance (txog 120Ω nyob rau hauv cov nqe lus ntawm Twisted Pair) vim muaj ntau yam sib kis kab. Thaum lub teeb liab xa mus rau lub davhlau ya nyob twg hauv cov kab sib kis, yog tias nws lub davhlau ya nyob twg impedance thiab cov yam ntxwv impedance txawv, nws yuav ua rau muaj kev cuam tshuam thiab cuam tshuam cov teeb liab waveform (sag lossis bulge). Qhov tshwm sim distortion tsis pom tseeb thaum txoj kab sib kis luv luv, tab sis nws yuav dhau los ua qhov hnyav dua vim tias cov kab sib kis tau ntev, ua rau tsis raug. Lub sijhawm no, Terminator yuav tsum tau teeb tsa. Lub 120Ω davhlau ya nyob twg resistor yog ntsia hauv FBs-PLC. Txhawm rau siv lub davhlau ya nyob twg resistor, thov qhib PLC kev sib txuas lus npog thiab tig DIP hloov mus rau txoj haujlwm "ON" (qhov hloov DIP yog teem rau "OFF" txoj hauj lwm ntawm lub Hoobkas), tab sis xyuam xim rau lub davhlau ya nyob twg Resistors tsuas yog ua tau. thov rau PLCs ntawm sab laug thiab sab xis ntawm lub npav, thiab tag nrho PLC hloov ntawm ob sab yuav tsum tau muab tso rau hauv "OFF" txoj hauj lwm, txwv tsis pub, RS-485 lub peev xwm thawb yuav tsis txaus.

Ib lub network 485 yuav muaj txog li 32 cov khoom siv txuas nrog, thiab cov kab siab tshaj plaws yog 1 km. Ob qhov kawg ntawm lub davhlau ya nyob twg load kuj kab siv impedance txuam resistors, txawm tias tag nrho cov resistances yog XXX ohms, los yog qhov sib npaug kuj muaj nuj nqis ntawm ntau ua ke yog 120 ohms (lub davhlau ya nyob twg load kuj muab rau ntawm lub nti cov ntaub ntawv).
