Installation - netvox R718IJK User Manual

6. Installation

1. R718IJK has the built-in magnet (as the figure below). When installed, it can be attached to the surface of an object with iron which
is convenient and quick.
To make the installation more secure, use screws (purchased) to secure the unit to a wall or other surface (as the figure below).
Note:
Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the
wireless transmission of the device.
1. The ADC sampling line, dry contact sampling, and current
sampling line of R718IJK are respectively connected according to
the wiring method of Fig. 1, Fig. 2, Fig. 3 and Fig. 4.
2. R718IJK detects the battery voltage of the device, the voltage
of the ADC sampling line, and the current of the current sampling
line according to the MinTime, and compares the values with the
last reported battery voltage value, ADC voltage value, and current
value. When the default variation is exceeded (the default variation
of battery voltage is 0.1V), the currently detected data is sent
immediately. Otherwise, the device will report data regularly
according to MaxTime. Data can also be reported by pressing the
button.
3. Dry contact sampling line will report data immediately after
detecting the change of dry contact status.
Note:
 When the dry contact is connecting, the data status bit is "1".
When the dry contact is disconnecting, the data status bit is "0".
 The wiring method of current detection is divided into 2-wire
wiring method and 3-wire wiring method. As Fig. 3 and Fig. 4
below.
The ADC detection function of R718IJK is suitable for the
following scenarios:
 Signal isolation and amplification in industrial field
 Linear actuator for solenoid valve and proportional valve
 Linear controller with magnetic switch
 Electromagnetically driven coil or high-power load
 Ground wire interference suppression
The signal isolation transmitter with output signal 0-24V.
The dry contact function of R718IJK can be used in the
following scenarios:
 Various switches and buttons
 Dry contact output of sensor
 The operating status of the equipment
 Door and window condition monitoring for home or business
The occasion is necessary to judge the sensor state by dry
contact signal.
The current detection function of R718IJK is suitable for the
following scenarios:
 Pressure transmitter
 Differential pressure transmitter
 Level transmitter
 Flowmeter
