What are the names of the isolation modules? For a long time, some engineers have been puzzled by the names of isolation modules, signal isolation modules, signal isolators, and isolated terminals. They do not fully understand the differences between these products, especially for newly-introduced automation system engineers.

It is generally believed that in the automation industry, isolation modules, signal isolation modules, signal isolators, isolators, isolated terminals, etc. are referred to as the same type of product, that is, connecting industrial field devices and control room devices. Electronic equipment that blocks ground loops and improves system measurement accuracy, operational reliability, and operational safety, usually DIN35mm rail-mounted.

Therefore, when you see the isolation module, signal isolator, and so on, you will understand that it refers to the same product. Different users are different in their habits.
