Control relays
This device has 6 relays for controlling the installation. The characteristics of the control relays are I
max
of 10 A at 110/230 Vac
(voltage-free. Note that to control elements with a greater power, it is recommended to use contactors in accordance with the
power required.
Important:
Remember to connect the neutral connector directly from the circuit to the element to be controlled.
Depending on the type of installation, the control relays will follow a different logic:
