• Connecting the input wires in parallel with other devices can cause signal
degradation, affecting all connected devices.
If you need to make a parallel connection, then
• Turn the burnout detection function OFF.
• Ground the instruments to the same point.
• Do not turn ON or OFF another instrument during operation. This can have
adverse effects on the other instruments.
• RTDs cannot be wired in parallel.
Wiring Procedure
To prevent electric shock, ensure the main power supply is turned OFF.
• If a strong tension is applied to the cable wired to the DXP, the terminals of the
DXP and/or the cable can be damaged. In order to prevent tension from being
applied directly on the terminals, fasten all wiring cables to the rear of the
mounting panel.
• Do not apply input signals that exceed the following values. This can damage
the DXP.
• Maximum input voltage
Voltage range of 2 VDC or less or thermocouples: ±10 VDC
Voltage range between 6 and 50 VDC:
• Maximum common mode noise voltage: 250 VACrms (50/60Hz)
1.
Turn OFF the power switch of the DXP and remove the input terminal cover.
2.
Connect the input signal wires to the input terminals.
