ISO Modules
The DFX flow meter uses ISO-MODs for input and output functions ISO-MODs are epoxy encapsulated electronic input/
output modules that are simple to install and replace in the field See
All modules are 2500 V optically isolated from
the DFX flow meter’s power and earth grounds This eliminates the potential for ground loops and reduces the chance of
severe damage in the event of an electrical surge
Three ISO-MOD options are available: 4…20 mA, dual-relay and rate pulse The DFX flow meter supports any two ISO-MOD
input/output modules All modules are field-configurable by using the keyboard interface Field wiring connections to
ISO-MODs are quick and easy using removable wiring terminals Configuration and connection of the various ISO-MODs are
described on the following pages
ISO Module Oeplacement
To remove an ISO-MOD, remove the two machine screws that secure the module in place and pull the module straight out of
the enclosure A 10-pin connection is on the bottom of the module that mates with the circuit board underneath To install
and ISO-MOD, push the module into the 10-pin connector and tighten the two machine screws Re-calibrate the parameters if
the 4…20 mA modules are replaced See
“Module Configuration Parameters” on page 35
