6.6 Analog Input Module (NR4412/NR4422)
The analog input module can transform high AC input values to relevant low AC output value,
which are suited to the analog inputs of the main CPU module. The transformers are used both to
step-down the currents and volta
ges to levels appropriate to the relay’s electronic circuitry and to
provide effective isolation between the relay and the power system. A low pass filter circuit is
connected to each transformer (CT or VT) secondary circuit for reducing the noise of each analog
AC input signal.
There are three types of analog input modules: NR4412-9I5U, NR4412-6I5U and NR4422-4I4U.
The view of the analog input module is shown in

NOTE!
The rated value of the current transformer is optional: 1A or 5A. The rated value
of the CT must be definitely declared in the technical scheme and the contract.
NOTE!
Because the rated value of the current transformer is optional, it is necessary to
check whether the rated value of the current transformer inputs is according to the
demand of the engineering scheme before the device is put into operation.
DANGER!
Never allow the current transformer (CT) secondary circuit connected to this
relay to be opened while the primary system is energized. The opened CT secondary
circuit will produce a dangerously high voltage. If this safety precaution is disregarded,
personal death, severe personal injury or considerable equipment damage will occur.
