When the PT ports need to be connected to a two-wire PT100/PT1000, use a short-circuit cable to
short-circuit GND and
– of the ports.
Connecting the 24 V Input Power Cable
4.10
The 24 V input power cable needs to be connected in the following scenarios:
• The 24 V DC power supply is used.
• The SmartModule connects to the power supply over the 12 V input power port, and the 24 V
input power port functions as the 12 V output power port to supply power to a device.
