PRG-1000 Isolation type safety barrier for detection and operation ends (circuit power supply)Detailed product description：

Product Description
PRG-1000 is a passive detection end and operation end universal isolation safety barrier. This product does not require an auxiliary power supply, and users can choose either the detection end or the operation end of the dual channel circuit as needed, without the need for intrinsic safety grounding, making it extremely convenient to use. The detection end is connected to a two-wire transmitter, and the operation end is connected to a valve positioner and an electrical converter.
