Hansheng Automation (Dongguan) Co., Ltd. is one of the most experienced manufacturers and suppliers of thinphy tpk4a voltage signal input safety barrier in China. If you're going to wholesale bulk cost-effective thinphy tpk4a voltage signal input safety barrier made in China, welcome to get pricelist and quotation from our factory. Also, customized service and OEM&ODM service are available.
The THINPHY TPK4A Voltage Signal Input Safety Barrier is made to provide safe protection from electrical shock hazards in explosive areas, such those found in oil, gas, chemical and pharmaceutical production and lab environments, while still allowing for accurate transmission of voltage signal: The voltage signal in the hazardous area is received by the barrier, and it isolates the signal from the hazardous area from the safe area, ensuring that the signal cannot become an ignition source in the explosive area. The input circuits are of high quality, maintaining accurate signal integrity even under harsh environment.
Moreover, the TPK4A adopts an easy installation and operation design. It is equipped with user-friendly labelling and interfaces. It accepts plural kinds of AC/DC voltage input signals and has passed international safety certifications. The TPK4A provides Circuit Breaker system with a higher level of safety, and facilitates the accurate, fast, flexible and reliable reading of voltage signal that circulates inside a system, which further improve safety for industrial applications and industrial risk avoidance.
