SMART-Net Expansion Board

The SMART-Net™ Expansion Board maximizes both the number of SMART-Sensor devices you can use and the combined SMART-Net cable length you can connect to a host controller. Powered by the host controller, the SMART-Net Expansion Board supplies power for up to 16 SMART-Sensor devices and does not repeat the SMART-Sensor signal, simplifying field wiring and providing a high degree of flexibility.
