cpu module has several models

NA200plus, is a set of three 16-point type cpu module. Three models were CPUplus-1601, CPUplus-1602 and CPUplus-1601N. New Plc logic controllers fully meet the functional requirements of the mechanical industry users, in the case of small volume only conventional CPU 1/4, still have high-speed counting, speed pulse and other advanced features, at the same time carefully for the ease of use of the service user, reflecting Nanda proud extension of the R & D team carved, excellence rigor; the high cost to the customer selection process more "conscious" of demanding to leave the choice.
, Plus fully reflects our pursuit of value for money concept. Please keep in mind, plus does not mean increasingly greater volume, price has become increasingly more expensive; but in a small volume can be increased more performance, low price better add value. We gave up minir named, because we need to have more product content, product customers can bring more imagination. Named plus, well reflect our intentions. I believe and plus mini contrast, can give our customers even more impressed.

Basic PLC operation

Process control can be simple and to what extent? We have a common household space heater.
Heater member sealed in a container, ease of system communications. This concept can be extended to a remote control home thermostat heater, communication distance of a few meters, usually voltage control.
Now, we are in this small, simple process control system to be expanded on the basis of which the control and configure a plant need?
Long-distance transmission line impedance, EMI and RFI voltage control scheme makes implementation very difficult, in this case, the current loop is a simple and effective solution. Kirchhoff's law by the current loop current loop at any point is equal to all other points in the current, which can offset the impact of the transmission line impedance. Because the loop impedance and bandwidth (a few hundred ohms and "100Hz), EMI and RFI spurious pickup issues are minimized. plc analog input output module system is useful for properly controlling such a factory production system.
