The module SBB4I2O24 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.
