NetPing Supply Voltage Sensor 995S2 | ACTIVE | 21 |
General usage conditions - for industrial and commercial usage in conditions of high humidity (0-95%, non-condensing). The device is not intended for domestic use. |
A sensor allows determining only the presence or absence of the voltage in the power outlet. A sensor does not determine the value of the voltage in the power outlet!
The output of the sensor is normally closed and normally opened relay contacts («dry contact», three wires: a normally closed wire — a common wire — a normally opened wire). When the voltage is below 65–78 V, relay contacts are opened. When the voltage exceeds 80–93 V, the state of the contacts is changed to the opposite.
A sensor is connected to the contacts IO and GND of the NetPing devices depending on which logic level is needed when there is no voltage. The connection polarity of the wires from the sensors is irrelevant.
The information about connecting a sensor is indicated in the document named «User Guide» that is specific for every device that is connected to the sensor. The configuration information about a sensor and its functionality is specified in the document named «Firmware Description» that is specific for every device that is connected to the sensor.
If there is a need to determine if there is the voltage in a 3-phase circuit, ensure there are three power outlets, one for each phase, and use three power sensors.
A sensor is shipped with an inseparable cord with the tips at the ends. A length of a cord can be increased using loop extenders for the sensor RC-4 that are plugged one into another or independently using any wire with a cross-section of no less than 0,4 square millimeters. Ideally, a maximum allowed loop length is 100 meters.
