The High Density Pulse Module - A8911-23 allows integration of up to 23 industry standard pulse meters and devices into a new or existing Modbus network.
Ideal for applications with a high density of pulse output devices, the A8911-23 minimizes the number of input modules required to convert the meter pulse counts into Modbus data. The A8911-23 takes in a variety of pulse output devices including gas, water, electric, and any other pulse output device, counts and stores the pulses and provides the totalized point count from all 23 channels via Modbus RTU to any Modbus master. This allows integration of pulse meters into any new or existing Modbus master such as the Acquisuite data acquisition server, a PLC, or any Modbus software based system.
Applications:
- Demand response program control and reporting
- Cost allocation to tenants and third parties
- Measurement & verification of energy savings
- Gas, water, steam, and BTU meters
- Monitoring performance of building systems (e.g., chillers, boilers, fans)
Features:
- DIN rail mounting makes installations quick and easy
- The onboard dipswitch sets the Modbus address
- Industry standard pulse inputs connect to most pulse output meters
- Check device status at a glance. LED indicators for each pulse input allow for fast indication and verification of pulses
- TX/RX communications status LED indicators for troubleshooting Modbus/RS485 wiring
- Non-volatile memory retains configuration and pulse count totals during power failures
A live demonstration of AcquiSuite and A8911-23 is available online via the Internet.
