Cobra3 is an interface system produced by the German company Phywe, which is widely used in the fields of physics, chemistry, biology, and industrial technology. It can be used in combination with a computer or a special component (COM-Unit), and provides multiple input interfaces and output ports.
The Phywe Cobra3 Interface System is a measurement, control and regulation platform used in physics, chemistry, biology and industrial technology labs. It can be operated with a PC via RS‑232 or with a dedicated COM‑Unit module.
The manual describes the hardware connections (analog and digital inputs/outputs, power supplies), the Measure software interface, and step‑by‑step experimental procedures, including data acquisition, analysis tools and calibration notes. This manual is written in Chinese.
| Analog inputs | 3 (1 component, 2 sensor) |
|---|---|
| Analog output | 1 |
| Digital control inputs | 3 |
| Timer/Counter inputs | 2 |
| Fixed voltage output | 1 |
| DC supply voltage | 5 V @ 0.2 A (stable) |
| External power input | 12 V @ 2 A |
| Analog input range | ±10 V / ±30 V (grounded) |
| ADC resolution | 12 bits |
The system provides three analog inputs – one component interface and two sensor interfaces.
It uses a stable 5 V DC supply capable of delivering up to 0.2 A.
An external power source of 12 V at up to 2 A can be connected.
