This ensures an output stage that can directly drive a relay with a 22-V switching voltage from a 24-V power supply. The transistors used (a 2N3055 npn and 2N2955 pnp in TO-220 packages) are ...

Here, the brown wire is for VCC (5-12VDC), the blue wire is for GND (0V), and the yellow wire is for OUT (Signal Output). The black wire is for MODE (Mode Selection) i.e. to set a normally-open or ...

Finally, as seen in the below diagram, the output of the H2010 optical slot sensor module drives a high-current PNP transistor which can turn on/off an external load like a relay or hooter. This ...

Analog pH sensors output a small analog voltage signal, generally in the millivolt range, that corresponds linearly to the pH value. This voltage signal is continuous and varies smoothly as the pH ...

Transistor instead of reed: As the first instrument of its kind, WIKA has launched a float switch with a PNP/NPN output signal. The model GLS-1000 detects the level of liquids with an accuracy of ...

Signal conditioning is the manipulation of the analog signal output of a sensor to prepare it, so the data acquisition system’s digitizer can measure the signal effectively and accurately.

Renesas’ ZSSC3240, announced earlier today, is a sensor signal conditioning chip that provides amplification and 24bit digitisation for bridge and half-bridge resistive sensors, followed by 26bit ...

A signal conditioner that provides clean sensor power supply and output amplification for precision dynamic measurement of pressure and vibration has been introduced by Measurement Specialties. The ...

Some photoelectric sensors, ultrasonic sensors, and rotary encoders generate a digital dc output called a push-pull signal. The external environment activates the sensor, which, in turn, closes a ...
