3.3.2 Analog Output

The F-5200 is provided with a single 4-20 mA output for instantaneous rate.

Active Output Conguration (Default)

The default conguration for this output is as an active 4-20mA output. In this conguration 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 Conguration

(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 conguration the output is electrically isolated from earth and from

input power. In this conguration, 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

certicate of calibration for information regarding the programmed full scale ow.

Contact ONICON for assistance if the full scale ow 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 certicate of

calibration for information regarding the programmed pulse value.

Contact ONICON for assistance if the scaled pulse output requires reprogramming.
