ASi Module to control Variable Air Volume Boxes
ASi Module to control Variable Air Volume Boxes
Description
The ASi module for controlling volumetric flow controllers (variable air volume terminal units aka VAV boxes) meets the requirement of ASi specification 3.0. It is used to control volumetric flow controllers (0 ... 10 V) using the analog output (0 ... 10 V).
The module also has an analog input (0 ... 10 V), for example to connect sensors for monitoring the air quality or for flap feedback.
The terminations are short-circuit and overload protected. An integrated watchdog function turns the output off when there is no communication on the ASi line. The transmission function is permanently monitored in the integrated ASi-3 node and ASi master.
Module connections are in the form of spring clamps.
