supply needs and connector pin-outs or cable color codes, consult your transducer
manufacturer's documentation.
Note:
The analog input Cmn pin must be connected! A disconnected Cmn pin can cause noise and
inaccurate readings.
Voltage Input, 4- or 5-wire
To minimize electrical interference:
• -In and Cmn must be connected. This connected should be made as close to the
transducer as possible.
• Use individually shielded twisted-pair wire.
• Typically, the cable shield should be connected to earth on one end only.
• If the transducer has only one common, connect the power supply and the RMC Cmn
to it. For best results, make this connection at the transducer.
Voltage Input, 3-wire
