As you can see, the Eastron SDM72-Bi is a very similar device to the Omron SEL2101 and the Schneider Electric EasyPower PM820. All three devices support Modbus RTU/TCP communication, have 8 input channels, and can measure voltage, current, and temperature. The main differences between the three devices are the number of channels, the input voltage range, and the price. The Eastron SDM72-Bi has the fewest channels, but it also has the lowest price. The Omron SEL2101 has the most channels, but it is also the most expensive. The Schneider Electric EasyPower PM820 falls in between the other two devices in terms of number of channels and price.

Ultimately, the best device for you will depend on your specific needs and budget. If you need a device with a lot of channels, then the Omron SEL2101 is a good option. If you are on a budget, then the Eastron SDM72-Bi is a good choice. And if you need something in between, then the Schneider Electric EasyPower PM820 is a good option.
