IoT Sensor Interface Appliance Features

Wahsega’s POE powered IoT Sensor Interface appliance is a very flexible sensor monitoring and control appliance. It can monitor up to four independent dry contact closure style sensors. It also has three independent relays for controlling external devices.

 Using a wide range of commercially available sensors the appliance integrates with the Carina building system to:

Monitor and provide proactive alerts

  • HVAC system efficiency
  • Building-wide air quality
  • Door security
  • Water leaks
  • Gas leaks, etc.
  • Cafeteria refrigeration equipment
  • Lightning strikes

Control building services

  • Sprinklers
  • Security Cameras
  • Access Control

Safety Certification Seals

Wahsega’s POE powered IoT Sensor Interface appliance is a very low power POE endpoint (less than 1W) allowing for long continued operation from a UPS during power outages. The IoT Interface device can monitor 4 independent environmental sensors with unique action plans for each one upon activation.
The IoT Interface device also has 3 high power relays capable of up to 30V DC 3A or 48V AC and 3A power loads.
All sensor inputs and relay outputs use standard wire screw terminating connectors. Two relays can support up to 16 gauge wires and the third supports up to 12 gauge wires.

The IoT Interface box is designed for Industrial temperature (-40C to +85C) operations so it can be deployed in a wide range of difficult environments.
