EBTRON wiring schematic for EF-A2000-U. Airflow measurement with temperature and alarm capability.
EF-A2000 Transmitter: Two field selectable (0-5/1-5/0-10/2-10 VDC*), scalable and protected analog output signals (AO1 = airflow, airflow1, airflow1-2, or airflow2-1, AO2 = airflow2, airflow1-2, airflow2-1, temperature, or alarm) * The VDC output circuit of the EF-A2000 transmitter can drive the input circuit of devices designed to measure 4-wire current loops with a resistive load ≥250 ohms.
