Intelligent Valve Controller Module for pressure independent energy measuring valves series EVG4U .. and EVF4U..
Extends the control valve by integration of flow- and temperature sensors towards a flow- and power – control valve.
Integration into temperature control loops either analog via 0/2..10V; 4..20 mA or via BACnet IP.
Provides temperature, flow, power and energy data via BACnet IP or into the Siemens Cloud.
Power Supply AC/DC 24 V.
