Features

1.Large display, standard 485 communication, with online and offline alarm, 98*98*130 meter size, 92.5*92.5 hole size, 3.0 inch large screen display.

2.The default English parameter settings, the function description is concise and clear, in line with most people's operating habits, and provide convenience for operators.

3.Carefully select materials and strictly select each circuit component, which greatly improves the stability of the circuit during long-term operation.

4.The new choke inductance of the power board can effectively reduce the influence of electromagnetic interference, and the data is more stable.

5.The design of the whole machine is waterproof and dustproof, and the back cover of the connection terminal is added to extend the service life in harsh environments.

6.Panel/wall/pipe installation, three options are available to meet various industrial site installation requirements.

Electrical connections

Electrical connection The connection between the instrument and the sensor: the power supply, output signal, relay alarm contact and the connection between the sensor and the instrument are all inside the instrument. The length of the lead wire for the fixed electrode is usually 5-10 meters, and the corresponding label or color on the sensor Insert the wire into the corresponding terminal inside the instrument and tighten it.
