Digital display meter Four-wire system 0-10V/2-10V 0/4-20mA analog input (receiving) DC8-25V With 2-way NPN outputs

main feature------

1. Power supply voltage range DC8-25V, power consumption 24V/50mA

2, four-wire mode (collection and power supply internal isolation), voltage/current type signals are supported;

3. Sampling resistance with current signal lower than 60 ohms (voltage drop less than 1.2V at 20mA);

4. Four-wire system + low acquisition resistance = easier to connect in series with current loop (0/4-20mA) to realize multiple display;

5. Panel buttons to set parameters, which is convenient for on-site debugging;

6. commonly used 0-10V 2-10V 0-20mA 4-20mA can be directly set by F1-0 parameter selection 0-5V, 0.5-4.5V, 2-8V and other signal ranges can be set by setting the offset and F1 parameter group The gain is normalized to the range of 0.0-100.0%. In addition, the maximum acquisition voltage signal can be extended to 40V (F1-0 selection);

7. display range (corresponding to the display physical quantity range) is set by the parameters F0-2 to F0-4;

8. NPN output is isolated from the acquisition and shares the ground with the power supply

9. Mechanical size: 79×43×25mm; installation opening: 76.5×39.5mm.

Application ------

1. Used to collect analog quantity (0-10V 2-10V 0-5V 1-5V 0-20mA 4-20mA) output sensor value display, such as pressure, temperature, dew point, displacement, etc.

2. It is used to receive the analog output (feedback) of various devices, such as the inverter (display frequency, output voltage, motor current, etc.), feedback of electric actuators (opening degree, etc.)

3. Four-wire system mode (relative to three-wire metering), which is easy to use in series for current signals; for devices with output power supply (but the power supply and analog output are isolated), the meter is safer for the device when using the power supply provided by the device.

4. It is also easy to be used in occasions where the voltage of a single battery cell is measured separately when batteries are connected in series.
