1-3 System Configuration with Motion Transmission
This device (model AVP701) has a function for motion transmission of the control valve.
To output the travel signal to the host monitoring device using analog values, configure
the system with motion transmission. Normally, the travel from fully closed to fully open
are output as 4–20 mA DC.
This shows an example of a system configuration for outputting valve travels detected
with this device as 4–20 mA DC analog signals.
With this system configuration, analog signals are output directly to the higher-order host
monitoring system from this device.
