Computer RS-23Z serial interface current loop circuit
This circuit is used in computer RS-232 serial interface and current loop circuit interface, it can transform voltage singal into 20mA current singal, the maximum transmission rate is 1200 bits. CCD IC1, T1 form receiver interface circuit, T2, T3 constitute transmitter interface circuit. When adds +12V, T2, T3 are conduction, the current outflows from T2 collector, and pass along the line then reach the ① of IC1, though LED of IC1, and pass along the line again then return to transmitter, the loop current is about 20mA. When adds -12V, T2, T3 cut off, there is no current in circuit. When current flows IC1 transmitter, the receiver is conduction, T1 is conduction, T1 collector sends out +12V electrical signal, when T1 cuts off, -12V electrical signal is sent to RS-232 through R4. Then to achieve use current loop to transmit digital signal.   (View)

Ni-Cd battery charging circuit

Published:2011/4/14 22:11:00 Author:Nicole | Keyword: Ni-Cd battery

Ni-Cd battery charging circuit
In the circuit, R1 is 10Ω, R2 is 200Ω. When the switch is up closed, the charging current is 60mA(constant current); when the switch is down closed, the charging current is 3mA(constant current). The total pressure drop of silicon diodes CR1, CR2 is 1.2V, and the Q1 emitter pressure drop is 0.6V, so the net pressure drop on R1 or R2 is 0.6V. 0.6V divided by the required charging current (using ampere), then it is the resistance of R1 or R2. LED indicates the work state of this charging circuit.   (View)
