NOVUS AUTOMATION 3/9
CONNECTIONS
This module operates only when connected to a PC USB bus, using the included type-A to mini-B cable. The following
figure shows all possible input connections.
Signal wires connected to all inputs should be kept separated from power wires, and when possible
installed inside of grounded electrical ducts.
Pt100 WIRING
Connections of channel 1 are on terminals 6, 7 and 8. For channel 2 on terminals 2, 3 and 4.
Connection with 3 wires from the sensor element to the module is necessary to cancel the
cable resistance error in the measurement. The 3 wires must have the same length and
gauge.
To connect a Pt100 with 2 wires, connect terminals 7 and 8 (channel 1) or 3 and 4 (channel
2).
THERMOCOUPLE WIRING
Connections of channel 1 are on terminals 6 and 7. For channel 2 on terminals 2 and 3.
Observe indicated polarity.
Cables for thermocouple connection must have the same thermo-electrical characteristics of
the thermocouple element (compensation or extension cable). Observe that both the
thermocouple and the compensation cable must be connected with correct polarity.
If compensation cable is not used or is not connected with the correct polarity, large
measurement errors will arise.
4-20 mA WIRING
Connections of channel 1 are on terminals 6 and 7. For channel 2 on terminals 2 and 3.
Observe indicated polarity.
