The Hioki U8974 4 Channel Analog Unit is a top-of-the-line input module designed for Memory Recorders. With its unique features, it offers an exceptional level of functionality and flexibility, making it an ideal tool for a wide range of applications.

One of the most notable features of the Hioki U8974 is its ability to provide direct high-voltage input of up to 1000 V DC and 700 V AC, without the need for a differential probe. This is particularly useful for primary and secondary measurements of UPS power supplies and commercial power supply transformers, as well as for recording primary and secondary waveforms of inverters.

Additionally, the module is capable of measuring high-voltage power supply lines, such as 380 V and 480 V systems commonly used in many countries. The Hioki U8974 can directly input high voltage signals, making it a reliable and efficient tool for any technician or engineer.

The module is also equipped with an isolated 2-channel input and a maximum rated voltage to ground of 1000 V AC or DC (CAT III), 600 V AC or DC (CAT IV). This ensures safe and accurate measurements in a variety of applications.

Furthermore, the Hioki U8974 provides high-speed sampling of up to 1MS/s, allowing users to capture and analyze fast-changing signals with ease. The module is also capable of measuring DCV and ACV high voltage input, making it a versatile tool for different types of measurements.
