Analog Level by BCD Thumbwheel Switch
BCD Thumbwheel Switch is used to input-set data in digital form, this can be read by digital circuits, uC and uP systems and PLC-SCADA Interfaces. Temperature Measurement and Control In the early transition of...
Voltage to Current Source 4-20 mA
The 0-1V to 4-20 mA Converter published earlier is a current sink, Here is a circuit that is a voltage to current converter but with a current source. You can use a LM358 or...
0-1V to 4-20 mA Converter
This two opamp circuit converts analog voltage signals to current (sink) signals in a proportional manner. Current signals are more immune to noise and cross talk, hence long wires can be used. Voltage Signal...
