Option CloudGate Smart Metering Expansion Card

Ideal for smart building & energy optimization

Monitoring energy production and consumption in a building has never been easier with the CloudGate Smart Metering card.
Not only can it interface with all wired interfaces that are used by meters, it can also monitor critical sensors, analog or digital inputs and trigger digital outputs.
This makes it an ideal card to be used in Smart Building use cases where it can optimally use the other advantages of the CloudGate IoT gateway platform such as a combination with wireless connectivity cards (LoRaWAN, Zigbee, wM-Bus, BLE…), an interface to the BACnet building management system, remote access etc.


Ideal for :

• Smart building monitoring
• Indoor & street cabinet monitoring
• Energy optimization

Selling points:

• Interface with all wired sensors used by meters.
• Monitoring of critical sensors, analog or digital inputs.
• Triggering of digital outputs.
• Can be combined with wireless connectivity cards (LoRaWAN, Zigbee, wM-Bus,…).
• Can be interfaced to the BACnet building management system, remote access etc.
• Interesting to be combined with our optional BACnet node in LuvitRED.
• In case of power loss, the gateway and the card can continue working for 30 minutes to 1 hour with our optional CloudGate battery.
  • Remark: if the battery is installed, the USB & Master M-Bus functionalities can’t be used (power supply).

Technical Specifications

Serial port


• (6-pins), 2kV galvanically isolated
• RS232 (Rx/Tx/RTS/CTS/GND) – 500Kbaud max
  or
  
• RS422 or RS485 (full or half duplex A/B/GND)
• switch for RS485 termination available in the UI



Mbus port


• Mbus Master
• up to 250 unit loads with 30V power supply
• up to 64 unit loads with 24V power supply
  or
  
• Mbus Slave
• Power supply + GND pin for Mbus master. These pins are also powering CloudGate so no separate power supply needed anymore.



I/O port


• (18-pins connector) for wired interfaces
• I2C interface 3.3V eg for environmental sensors in electricity cabinet (temp, humidity etc) - 4 pins
• 5 multi-purpose IO’s eg to monitor alarms in electricity cabinet or to drive door opening/ventilation relays - 11 pins
  • Digital input (0 - 30V) (including dry-contact pulse counter)
  • Analog input (0 - 10V)
  • Current Loop input (4 – 20mA)
  • S0 pulse-counter input
  • Digital output (0 – 3.3V)
  • Open Drain output (< 250mA, 0 – 30V)
