3.3.2 Analog Output
The F-5200 is provided with a single 4-20 mA output for instantaneous rate.
Active Output Configuration (Default)
The default configuration for this output is as an active 4-20mA output. In this configuration the
output is electrically isolated from earth, but is common with input power. The blue wire is the
active (+) 4-20mA signal and the brown wire is the (-) 4-20mA return.
Loop Powered Configuration
(Only the output is loop powered, the meter still requires power.)
By changing the position of switch S1 located inside the enclosure, it is possible to loop power
the 4-20mA output. In this configuration the output is electrically isolated from earth and from
input power. In this configuration, an external DC voltage (+) VDC (12 – 24 VDC) is applied to the
yellow wire and the blue wire is the (+) 4-20mA signal. The brown (-) 4-20mA return wire is not
used.
The 4-20mA output is programmed at the factory. Refer to the attached laminated tag or the
certificate of calibration for information regarding the programmed full scale flow.
Contact ONICON for assistance if the full scale flow rate requires reprogramming.
3.3.3 Pulse Output
The F-5200 is provided with a single scaled pulse output for totalizing. This is an isolated dry
contact output. Maximum contact ratings are 50VDC @ 100mA. Pulse duration is 500ms.
This output is programmed at the factory. Refer to the attached laminated tag or the certificate of
calibration for information regarding the programmed pulse value.
Contact ONICON for assistance if the scaled pulse output requires reprogramming.
