The A8332-8F2D Flex I/O Module provides a convenient way to bring data from up to 8 industry standard meters and sensors into facility management/monitoring systems.
As a standalone module, the A8332-8F2D (Flex I/O Module) can be incorporated to any new or existing Modbus Network (BAS, EMS, etc). By using the Windows based Obvius Configuration Console (OCC), users can select input types (pulse, analog, resistive, etc.) and verify communication and wiring. The Flex I/O Module is a quick and cost-effective way to aggregate data from multiple device types and bring that data into any Modbus system.
Applications:
- Load aggregation for Demand Response
- Cost Allocation
- Measurement & verification of energy savings
- Easily add meters & sensors to any Modbus network
- Monitoring performance of building systems including photovoltaic production

Full Review
- 8 user selectable inputs to aggregate pulse, analog, and resistive meters/sensors
- Non-volatile memory retains configuration and pulse counts
- 2 digital outpus
- Digital outputs can be linked with pulse inputs for pulse splitting appliacations
- LED indicators allow visual verification of communication status/signal
- Din rail mounting for quick installation
