Product Application: Connection Terminals in Isolators]: Isolators are installed by guide rail and wiring by wiring. This product is called Isolation Terminals and is suitable for installation in cabinets. With the development of science and technology, the design of isolation terminals is becoming smaller and smaller, and the purpose of miniaturization is to occupy less space. Of course, users should be allowed to install densely, and there will be heat dissipation in intensive installation.

The isolator is mounted by guide rail and connected by wiring. This product is called isolation terminal and is suitable for installation in cabinet.

With the development of science and technology, the design of isolation terminals is becoming smaller and smaller, and the purpose of miniaturization is to occupy less space. Of course, users should be allowed to install intensively, while intensive installation has heat dissipation problems, so internal power consumption must be reduced. So the value of internal power consumption should also be paid attention to when choosing.

At present, there are many isolation terminals with CPU as the core in the market, which have the functions of field compilation and communication, and have high flexibility. For customers, it can reduce the amount of inventory and reduce the backlog of funds. The isolation terminals with CPU as the core will become the mainstream in this field.

You Le believes that there is another way to isolate the transmitter. Sensors and transmitters are integrated and must be placed in designated locations. At this time, the isolation terminal is usually placed in the cabinet of the central control room. The isolation terminal in the cabinet is used to distribute power for the field transmitter. Which kind of isolation terminal to use depends on the situation of the PLC interface.

Field debugging may result in mismatch between instrument and PLC interface. The transmitter output 4-20mA for four-wire transmitter and the receiver interface 4-20mA for two-wire loop power supply. Direct connection will cause power conflict. The solution is to use isolation terminal to receive and isolate the 4-20mA in the field, and install a special circuit in the output part of the isolation terminal to match the power supply interface mode of the secondary circuit of the PLC.
