accQcomm™ Digital/Analog Interface Module - 1

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. accQcomm™ Digital/Analog Interface Module Ordering Information Description Part Number accQcomm ADFM digital/analog interface module 68-7500-010 Specifications accQcomm Digital Interface Module Physical/environmental Dimensions (H x W x D): 2.75 x 10.5 x 5.6 in.
