13) 4…20mA outputs connections (AO1 to AO4)
4…20mA outputs are used to send information to a building management system or to control a dosing
device via a 4…20mA signal. The analog outputs are generative and operate with an internal voltage of
12 VDC. The maximum load is 500Ω.
4…20mA outputs are fully configurable. You can assign any parameter (measured or calculated) in
regulation or data transfer mode.
