FEATURES OF NODE Model NSA10
Model NSA 10
This system allows the delivery of power on a load, such as the water pump, that is connected to its
output, but also the protection of it against short circuits or abnormal overloads.
This node has a provision for detecting levels with discrete sensors (with 4 levels) and with two
overflow sensors.
The device can be controlled to switch the flow of energy to the pump on/off in two ways: locally
via a normal switch (on/off) and also remotely via the control unit. The latter displays the status
(on/off) of the device and also the status of its protections and of the level sensors.
Inputs
The device, as may be seen in Figure 12 essentially comprises three types of connectors. Connector
J1, the device input; connector J4 with six pins usually used to detect the levels of a tank with a
discrete sensor with four levels and connector J5 with 4 pins used to detect the overflow signal from
two separate tanks.
Outputs
The output is connector J2, as shown Figure 13 on some models connector J3 cannot be fitted)
connector J2 will have a power output and two contacts (Wire A and Wire B) for connecting the
control switch.
Electrical Specifications
The electrical specifications of the device are:
•
Supply voltage 12 V
•
J1 6-pin connector input, capacity 5 A
•
J2, J3 the two possible outputs controlled respectively by the corresponding switch
connected to contacts CON_01 and CON_02 respectively protected with the 3 A
SMART fuse
•
J4, J5 two connectors for the level sensors.
