Generally speaking, the switch is generally referred to as an Ethernet switch (excluding telecom program-controlled switches, otherwise the explanation is too complicated). Ethernet switches are generally classified into: commercial (Ethernet) switches, industrial (Ethernet) switches, and home (Ethernet) switches. Commercial switches are generally used in enterprise office networks and other occasions. The general form is rack-mounted. […]

The specific implementation methods can be as follows: 1. Directly connect to the FX2N programming port, using Mitsubishi’s built-in FX2N programming port protocol. This method does not require any setup and programming on the FX2N. It only needs to be programmed on the Profibus master station to continuously read and write slave data. The FX2N […]

The actuator is an indispensable part of the industrial process control automatic regulation system. The actuator used depends entirely on the valve, and the actuator is only the drive. The actuators configured by the regulating valve are nothing more than the pneumatic actuator, the electric actuator, and the hydraulic actuator (electro-hydraulic actuator). Accordingly, the regulating […]

Burn insurance or frying tube Mainly check the large filter capacitor on 300V, the diodes of the rectifier bridge and the switch tube. The problem of anti-interference circuit will also lead to burn-in and blackout. It should be noted that the burnout will generally burn the current sense resistor and the power control chip due […]

The coolant temperature sensor has a thermistor inside. When the temperature of the coolant changes, the partial pressure value measured by the ECU through the THW terminal changes, and the ECU determines the coolant temperature based on the partial pressure value. It is installed in the engine block water jacket or coolant line and is […]
