5.4 Pulse output
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 48V AC. The relay also provides 2500V isolation, between the sensor's electronics and the outside world.
The pulse output is available at the White and Green wires. Electrically this is a volt, or potential free contact, and when selected as
a low flow alarm is configurable NO/NC.
The pulse output can be set up to operate one of five modes:
• Volumetric
• Energy (HM versions only)
• Frequency
• Low Flow Alarm
• Loss of Flow (Signal) Alarm
The Alarm functions allow you to set the alarm switch to Normally Open or Normally Closed.
5.5 Pulse output connections
The isolated pulse output (labelled PULSE A and PULSE B) is provided by a SPNO/SPNC MOSFET relay which has a maximum load
current of 500mA and maximum load voltage of 48V AC.
The relay also provides 2500V isolation, between the unit's electronics and external equipment.
NOTICE
This output is suitable for SELV circuits only
Electrically this is a Volt, or potential free contact and, when selected as a low flow alarm, is configurable NO/NC.
