The interference of SHINKAWA MP-2S is hard to remove, and it will cause economic loss and accident disaster in serious cases. The unique built-in barrier function IO module developed by Ushio has strong anti-interference performance compared with ordinary IO modules, reaching the level of industrial anti-interference grade 4a. Although ordinary IO modules also have isolation performance, their isolation strength is far from enough in occasions of great interference, and they must be used with an isolator.

SHINKAWA MP-2S built-in barrier function IO module can not need to configure the isolator, but also to ensure the accuracy and reliability of the signal, for customers to save a lot of cost. It supports intrinsically safe universal input and intrinsically safe distribution of analogue signals on site, which saves safety barriers, installation space and wiring maintenance workload; it supports dual or triple redundancy configurations of a variety of fieldbus communication modules, and is open to connecting with most of the mainstream control systems, so as to realize the high reliability and safety requirements of the control system in explosion-proof occasions.

SHINKAWA MP-2S to prevent the ignition of these dangerous sources, usually with explosion-proof isolation devices, namely, safety barriers, through the current-limiting and voltage-limiting circuits to limit the energy sent to the field circuits, so as to prevent non-intrinsically safe circuits of the hazardous energy strung into the intrinsically safe circuits. As an auxiliary unit, safety barriers are often used in DCS/PLC systems. IO signals located in the explosion-proof area first pass through the safety barriers and then are connected to the corresponding IO modules of the system, which can complicate the design of the system.
