Take the connection terminals of each fan to an outlet of the electrical cabinet, single
phase 50/60 Hz, 220/240 V AC. Consumption: 0.15/0.13 A, 23/20 W.
Connect as shown in the image the terminal
labeled + 24 V DC to an external 24 V DC
power supply of the electrical cabinet and the
other one labeled PLC INPUT to a PLC input.

Connect as shown in the image the terminal
labeled +24 V DC to an external 24 V DC
power supply of the electrical cabinet and
the other one labeled PLC INPUT to a PLC
input.
IMPORTANT. Remember to manage the
chosen PLC input in the PLC program to
generate an error when exceeding the limit
temperature (160 °C) detected by the
sensor and to open the contact.
