S9.42
Integrator with RS485 interface output (Modbus RTU Protocol)

S9.42 is an integrator with a built-in analog integral circuit and RMS calculation, which converts to RS485 interface output (Modbus RTU Protocol), having three options of power supply 5VDC, 12VDC, 24V DC and with its overall waterproof grade IP66.

1  Features

S9.42 can be used together with any type and sizes of Rogowski coils like series of Y-FCT, NRC, ZRC, MRC, TRC, etc.
Rated current can be customized according to customers' requirements.

-RS485 interface output
-High bandwidth from 30Hz to 5KHz measurement
-S9.42 conjunction with Rogowski coil are a very flexible system, suitable for measuring devices, electric power
 monitoring and analysis, cooperating with traditional meters for measurement and so on. Because of many
 advantages of Rogowski coil, it can solve a lot of problems that can't be solved by traditional CT. It is a perfect
 solution to replace traditional CT.
