Advantages of DC isolator
In the process loop signal isolators are used in a way to use DCS or PLC separate card or bring the isolation transmitter (part of the equipment can be done), can also be implemented with signal isolator. In comparison, the signal isolator has the following advantages:
• The vast majority of cases, signal isolator + non-isolated card cheaper than using separate card
• Signal isolator in isolation than isolation, superior EMI performance more
• Flexible application of signal isolation, but it also signals and signal distribution and interface conversion functions, more convenient to use
• Usually with single channel signal isolator, dual-channel, the channel between fully independent, system configuration, daily maintenance more convenient.
