*1: Use a 2-wire shielded cable with an outside diameter of 6 to 12 mm.
*2: Connect the analyzer to ground. (Class D ground: 100 ohm or less)
*3: This line is connected to a distributor or 24V DC power supply.
*4: Terminal numbers for each sensor module are shown below.
*5: Two modules of the same kind of measurement/sensor type can be installed. When measuring inductive
conductivity or pH/ORP with the SENCOM sensor, only one module can be installed.
*6: The terminal box may be necessary depending on the sensor cable length and the distance between the
analyzer and the sensor.
The SENCOM sensor is to be connected directly to the analyzer without a terminal box.
*7: Two outputs, output 1 and output2, of PH201G or SDBT are same signals.
