Imported isolatorThe main purpose is to measure the pressure, position, capacity, flow rate, etc. of some fluids, gases, and other media, and then display the data in a timely manner, so that the staff can grasp the hand data and manage and control the work site in a timely manner. Therefore, it occupies an important position in enterprise production, which can ensure the normal operation of enterprise production and improve work efficiency.
The operation status of the imported isolator is as follows:
(1) If a short circuit occurs in the circuit, the isolator will be in a disconnected state within 23 milliseconds;
(2) Close the isolator near the loop controller at 10 millisecond intervals and provide power to the next isolator in the circuit.
(3) When a short circuit occurs after a certain isolator is closed, the isolator will disconnect again within 10 milliseconds.
There are many demands driving the use of isolation components. The main driving factors for imported isolators are component protection, user safety, signal level conversion, and compliance with safety regulations. In all cases, isolation components add value to the system by implementing additional functionality and ensuring safe operation of the system.
What impact will adding an imported isolator have on my circuit?
In many cases, performance will improve, and in all cases, component security will be enhanced. Isolation devices allow multiple power domains to coexist and communicate, which means sensitive circuits and switch circuits will be isolated. The large-scale integration of modern digital isolation technology means that the number of circuit components can be reduced. Performance, efficiency, size, and cost are all aspects that may be affected when adding isolation devices.
Imported isolator power supply methods: Common power supply methods for isolators include # power supply, loop power supply, and output loop power supply.
Imported isolator for power supply: requires a DC power supply of # 20~35VDC.
The advantage of this method is high isolation transmission accuracy; The power supply, input, and output are isolated, and the multi-channel system power supply does not need to be isolated, ensuring high anti-interference performance. The input can be converted to other types. In practical industrial monitoring systems, the use of DCS, PLC, or other display instruments with card internal power supply is becoming increasingly widespread.
