![]() ![]() ![]() It is necessary to provide 24V power distribution power for transmitters and other instruments, and at the same time to collect, amplify, calculate and anti-interference the input current signals. It is necessary to collect, amplify, calculate, and perform anti-interference processing on the input voltage, current or frequency, resistance and other signals, and then output the isolated current and voltage signals, which are safely sent to the secondary instrument or plc \ dcs for useĢ) Power distributors: Two-wire transmission mode is generally required in industrial sites. What are the main types of signal isolators?ġ) Isolator: In order to increase the load capacity of the instrument and ensure that the instruments connected to the same signal do not interfere with each other in industrial production, improve electrical safety performance. It can overcome the inverter noise and various high and low frequency ripple interference. The standard series guide rail structure is easy to install and can effectively isolate: the potential between input, output and power and ground. It is the transmitter, instrument, inverter, solenoid valve PLC / DCS input and output and communication. Suppress the interference of common ground, inverter, solenoid valve and unknown pulse on the equipment meanwhile, it has the function of limiting the voltage and current of the lower-level equipment. Attenuate the influence of environmental noise on the test circuit.ģ. ![]() Ensure absolute independence between transformed signals, power, and ground.Ģ. At the same time, the power supply of the isolated signal is isolated. First, the signal of the transmitter or instrument is modulated by the semiconductor device, and then isolated and converted by the light or magnetic sensor, and then demodulated and converted back to the original signal before isolation. ![]()
