Besides, the product adopts an external switch power supply, safe and reliable, which makes it suitable for outdoor engineering applications. The built-in opto-isolator and 600W surge protection circuit can provide an isolation voltage of 2500V, which can effectively suppress interference such as surge and electrostatic discharge. In order to ensure the safety and reliability of data communication, the RS485 interface adopts photoelectric isolation technology to prevent lightning surge from being introduced into converters and equipment. Its transmission reaches up to 115.2Kbps. In addition to the excellent performance of conventional signal isolator, a CPU control unit can also be added in a signal isolator to realize the field programmable function and RS485 communication function.This 4-Port RS485 bus split hub is specially designed to meet the requirements of RS485 large-scale systems in complex electromagnetic environments. Moreover, it can also output various signals that the user needs. The isolator has the signal conversion function and can accept DC standard (or non standard) signal, thermocouple signal, RTD signal, potentiometer signal or even AC signal. The 4-wire external powered signal isolator can provide power supply to a 2-wire transmitter, thus it avoids providing additional power supply to the transmitter, and also provides the signal isolation function. Moreover, the active signal of the 4-wire transmitter will be output to the receiving device after isolation, thus it not only avoids the power conflict, but also isolates the signal. When connecting an output loop powered signal isolator, it is powered by the receiving device through a signal output line. The signal access terminal of the receiving device is equipped with a 24V power supply, however, a 4-wire transmitter is used on site and the output signal is an active signal.

Any equipment fails, it will not affect the entire loop and the other equipment. Two receiving equipments are completely isolated. Two output signals can be both identical, and different from each other. On the other hand, it can effectively remove the radio frequency and electromagnetic interference that circuits may suffer during transmission. On the one hand, the signal isolator can solve the problem of different ground reference points generated when the ground loop is connected with the equipment. Temperature: 0~50℃, humidity: ≤85%RH, far away from caustic gas We recommend you another signal isolator ATO-SIGNI-602S, which has up to 2 input channels & 4 output channels, types of signal 4-20mA, 0-10mA, 0-20mA, 0-5V, 1-5V and 0-10V.
