PLC Display Functions Monitoring
- Used to collect analog (0-10V 4-20mA) and display the value of the output sensor, such as pressure, temperature, dew point, displacement, etc.
- Used to receive analog output (feedback) from various devices, such as frequency converters (display frequency, output voltage, motor current, etc.), feedback from electric actuators (opening, etc.)
- 4-wire mode (relative to 3-wire), it is easy to use in series for current signals; for devices with output power (but the power supply and analog output are isolated), it is safer for the device when the meter uses the power provided by the device.
Feature
- Power supply voltage DC8-25V
- 4-wire mode ( acquisition and power supply are internally isolated ) , voltage signals /current signals supported
- The current signal is lower than the sampling resistor of 60 ohms (the voltage drop is less than 1.2V at 20mA)
- Four-wire system + low acquisition resistance = easier to connect in series to the current loop (0/4-20mA) to achieve multiple displays
- Panel buttons are used to set parameters to facilitate on-site debugging
- The commonly used 0-10V 4-20mA can be directly
- Parameters F1-0 parameter to select 0-5V, 0.5-4.5V, 2-8V and other signal ranges by setting the offset and in the F1 parameter group.
- Gain is normalized to the range of 0.0-100.0%.
- Parameters F1-0 Maximum voltage signal is extended to 40V
- Parameters F0-2 to F0-4 The display range (corresponding to the displayed physical quantity range)
- NPN output isolated from the acquisition and shares the same ground with the power supply.
