accQcommâ„¢ Digital/Analog Interface Module0 pages

The accQcomm™ digital/analog interface
module accepts RS-232/RS-422 serial data from
up to three Isco ADFM® flow meters (ADFM
Pro20, Hot Tap, accQmin™, or H-ADFM) and
converts the data into an industry-standard
digital protocol (MODBUS or Ethernet) or
industry-standard analog signal (4-20 mA).
Either method allows easy interface with
SCADA/DCS or other secondary control or
data recording systems.
Additionally, the accQcomm's pass-through
capability allows the flow meters to be accessed
using a number of communication protocols,
including wireless Ethernet and cellular modems.
The module is wall or console mountable and is
powered with 12 to 24 VDC.
Applications
Provides real-time SCADA/DCS interface for
applications in
Wastewater collection and treatment
Stormwater collection and discharge
Industrial process and treatment
Standard Features
Three serial inputs, RS232 or 422, for
simultaneous integration of up to 3 different
ADFM systems.
Modbus or Ethernet interface for digital
data access.
Four independent, opto-isolated 4-20 mA
analog outputs, programmable for any
measured parameter.
Sums and averages of data from the three
instruments selectable as an output.
Pass-through mode for flow meter access via
a single, shared Ethernet or serial connection.
Eight optically isolated relay outputs for
issuing alarms based on user-defined
conditions.
