2.5.1 Inputs
The auxiliary inputs can be configured for different types of control:
1) Digital/analog control:
PIN 1:
digital input, clean contact (maximum voltage 5Vdc, maximum current 1mA); the contact is configurable if
normally closed or open (see par. 5.7 “INPUT TYPE”)
PIN 2:
An input for an external analog signal, configurable as 0-10V or 4-20 mA .
PIN 3:
Earth contact for the connection of all inputs.
The following figure shows the relationship between the analog signal on input and the setpointSP to be activated.
