Since 1974, Watanabe Electric Industry has been developing and selling signal converters, and have been broadly adopted in the areas of factory automation, process automation and building automation.

Watanabe Electric Industry  offer two types of signal converters, an easy to maintain plug-in type and a terminal block type, and with our abundant lineup, we have the ability to quickly deliver products to customers. The noise resistance performance has greatly improved in our recently released products, with a long term guarantee of 5 years, and are designed taking into the consideration the various installation environments of customers.

While advanced digital technologies are required in order to realize more accurate automation, Watanabe Electric Industry  digital instruments have achieved remarkable development in response to the needs of the times.

Watanabe Electric Industry  support a broad range of digital measurements for facilities and production from digital panel meters for common displays (voltage, current, temperature, revolutions, pressure, resistance, frequency and etc.) known as "Digi-pane" (registered trademark of Watanabe Electric Industry), to advanced control systems (determination functions, communication complex functions and etc.) and have achieved the leading lineup in the industry.

Watanabe 3 port Isolation Amplifier (High Gain) ZM-310

3 port Isolation Amplifier (High Gain) ZM-310

Watanabe 3 port Isolation Amplifier (High gain) ZM-310 is a high gain type 3-port isolation amplifier, and supports minute input (mV). In addition, since a transformer with a high coupling coefficient is used, loss is small and linearity is extremely excellent. Although it is a smalllinearity transformer, it has a high withstand voltage and high airtightness due to the case filling structure, making it ideal for isolating various signals such as transducer signal isolation and instrumentation signal isolation. Board mounting type with 2.54mm pitch allows for easy board layout.


  • High gain
  • Compact and lightweight
  • Low current consumption
  • High CMR common mode noise rejection ratio
  • High insulation, high withstand voltage
