VTop Control Valves
M/VTOP-M/E ed. 01 2020
3.5.2.4 – Fail safe port for binary inputs (Optional on request)
The fail safe port (terminals 12 and 13) enables activation
of the actuator in a safe position which can be calibrated,
applying a voltage of 24 volts tele
3.5.3 – OUTPUT TERMINALS
3.5.3.1 - Active feedback signal
The terminals from 4 to 6 give an active feedback signal,
parameterised with a range of 0-20 mA or 0-10 V.
3.5.3.2 – Additional signalling limit switch (Optional on request)
The activation points of the optional additional signalling
limit switch can be freely calibrated via cams.
Terminals 18/19 and 20/21 are clean opening or closure
contacts.
The standard signals are calibrated to 230 VAC/ 5°.
The special limit switches with gold-plated contacts are
available for low power (up to 100 Ma and 30V ).
3.5.3.3 – Power supply for process sensor
The terminals 14 and 17 offer the advantage of non-
adjusted output from 21 to 40 VAC, at a maximum 100 Ma
to power an external process sensor.
3.5.3.4 – Anomaly signalling relay (Optional on request)
This normally open clean contact relay (terminals 7 and 8)
allows anomaly signalling to the control cam. For
configuration, use PSCS communication software.
