This device supports two - wire bus input, which is simple and convenient for wiring. It also supports four - wire system input with stronger load - bearing capacity. The non - intrinsically safe side and the intrinsically safe side are electrically isolated. A short - circuit on the intrinsically safe side does not affect the non - intrinsically safe side. Moreover, it adopts lightning - protection design to avoid damage caused by lightning strikes.
