Input teeb liab

Hloov kev sib cuag / sib thooj hloov

Supply voltage los ntawm sensor sab ntawm qhov chaw

8 V

Lub teeb liab input yam ntxwv

On-site input tam sim no:> 2.1mA, nws txhais tau tias ON; On-site input tam sim no:

Transistor tso zis yam ntxwv

NPN hom transistor emitter lossis collector qhib Circuit Court tso zis, tsav muaj peev xwm: tso zis tam sim no ≤20mA (1.2KΩ), sab hauv siab tshaj plaws tam sim no 100mA. Nruab nrog luv-circuit tiv thaiv tam sim no

Switched tswj ntawm inverted theem thiab ib txwm theem ntawm outputs ec

Thaum lub dial hloov K1 nyob rau ntawm "ON", lub transistor tso zis ec nyob rau hauv inverted theem

Thaum lub dial hloov K1 nyob rau ntawm "OFF", lub transistor tso zis ec nyob rau hauv ib txwm theem

Thaum K2 nyob ntawm "ON", lub voj voog yuav xaiv lub teeb liab qhia lub tswb ua haujlwm

Qhia lub teeb tswb muaj nuj nqi

Field input tam sim no> 7mA, lub tswb luv luv (SC), ntawm qhov chaw tawm tswv yim tam sim no

Number of input thiab output

2 input 2 tso zis

Siv tau cov khoom siv teb

Kev sib cuag qhuav lossis NAMUR sib thooj hloov raws li DIN 19234 tus qauv.
