WIRING SENSORS AND TRANSDUCERS
Thermistors: The unit will accept 2.8K and 10K thermistors. These
should be wired to an input terminal and the adjacent ground
terminal. For compatible thermistors check the thermistor data in
the appendices.
Dry Contacts:Only contacts which have no voltage or current
applied may be used. Connect the contact to an input terminal and
an adjacent ground terminal. Do NOT try to monitor a contact that
switches 120VAC. This will permanently damage the unit.
4-20mA: A 4-20mA transducer requires you to have an external DC
power supply for the transducer. Make sure the input is configured
for 4-20mA.
Connect the positive wire of your transducer to the positive terminal
of your DC power supply. Connect the negative terminal of the
transducer to an input terminal on the CPP Monitor 2000. Connect
the negative terminal from your power supply to the adjacent
ground terminal on the 2000.
