Kev Hloov Cov Khoom Siv Transistor Input Cov khoom siv tiv thaiv kev nyab xeeb cais tawm xa cov teeb liab nkag los ntawm cov khoom sib txuas lossis cov khoom sib ze hauv thaj chaw txaus ntshai los ntawm cov khoom siv tiv thaiv kev nyab xeeb cais tawm mus rau thaj chaw nyab xeeb nrog cov khoom siv transistor. Cov khoom siv tswj cov khoom siv transistor passive nrog cov yam ntxwv resistive. Cov khoom siv tso zis muaj plaub lub xeev txhais: kev tiv thaiv ceeb toom luv luv ≤ 240 Ω, 1-lub teeb liab 1.4KΩ ≤ tus nqi tiv thaiv ≤ 1.6KΩ, 0-lub teeb liab 13KΩ ≤ tus nqi tiv thaiv ≤ 14KΩ, thiab kev tiv thaiv ceeb toom tawg > 100KΩ. Cov yam ntxwv tso zis no teb rau lub xeev kab ntawm kab teeb liab. Cov dip switches ntawm lub module siv los teeb tsa cov khoom siv nkag thiab cov khoom siv tso zis rau tib qho kev taw qhia lossis rov qab tswj, nrog rau teeb tsa cov haujlwm ceeb toom qhia txog kab txhaum. Cov khoom no xav tau lub zog hluav taws xob ywj pheej, nrog rau lub zog hluav taws xob cais tawm, cov khoom siv nkag, thiab cov chaw tso zis.
