The module SBB4I2O230 is an I/O module for monitoring and control of two fire dampers. The module has 4 contact inputs for position feedback and 2 relay outputs for control of fire damper actuators. The I/O module is implemented in a robust junction box for a decentralized installation near the two fire dampers. The I/O module is part of the Smart building product range. Several I/O modules can be multi-dropped via the same Dupline® 2-wire bus and thus the wiring to the controller can be significantly simplified.

Main Technical Features

• Ready-to-use junction box housing for fast and easy decentral installation
  
• One I/O-module can control and monitor two fire dampers
  
• Fast and easy wiring to the main controller through the Dupline® bus (free topology and long distance capability)
  
• Up to 64 fire dampers on one Dupline® bus segment
  
• The system can be interfaced to the main controller via BACnet or Modbus
