SMART-Net™ Expansion Board
SMART-Net™ Expansion Board
For SMART-Net™ devices that use terminal-block connections instead of modular RJ11 connections, 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 externally or by the host controller with 24 VAC or VDC, 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.
