In addition to their onboard I/O interfaces, the CG, CV, and FEC family equipment controllers feature a Sensor/Actuator (SA) Bus to gain additional input and output interfaces and to connect to networked end devices. SA Bus devices include:

  • Input/Output Expansion Modules (XPMs and IOMs): add additional input and output interfaces to an equipment controller to aid in operating large or complex equipment (such as central plants or large air handlers).
  • Network Sensors: measure temperature, humidity, CO2, and occupancy, and transmit this information to the equipment controller. Various mounting options are available, including wall-mountable and duct-mountable sensors.
  • Variable Speed Drives (VSDs): control fan and pump speed, and can be controlled directly by the equipment controller over the SA Bus.
