3.4.2 Output cable connector
The output cable provides a current source that can drive a maximum load of < 600Ω and 3 digital output pairs for pulse, frequency
or alarm outputs.
The isolated pulse output is provided by a SPNO/SPNC MOSFET relay which has a maximum load current of 500mA and maximum
load voltage of 24V AC/DC.
WARNING!
This Output is suitable for selv circuts only
The pulse output is a Volt or potential free contact and when selected as an alarm, is configurable
as NO/NC.
The current output is available on the white (high polarity) and black (low polarity) wire pairs (pins 1&2 on the connector). The
alarm current due to an out-of-bounds condition must be set outside the working range
Using the instrument's menu system, you can:
• Select the current output function Off/On
• Select the current output range (set the current range, where 4-20mA, 0-20mA, 0-16mA
are common ranges), but the device is capable of generating currents of up to 24mA
• Calibrate the current output signal to a required flow range
• Select the alarm cause (and alarm current for the current output)
• Set a trigger value for the alarm when it is associated with Under Value or Exceeds Value
• Set current trim values to accommodate any inaccuracies in the user's system
