Power & Communications for Multiple Alicat Instruments

Alicat’s BB9 multi-drop breakout boxes make building your own local flow control network easy. Control up to 9 Alicat flow or pressure instruments from a single computer or programmable logic controller (PLC) connection. Breakout boxes also distribute power to all connected devices from a single power source. Each BB9 is built into a light, yet rugged, composite chassis that can be mounted in any orientation via its 3/16″ diameter mounting holes.

  • Compatible with instruments that have 8-pin mini-DIN.
  • Communicate with all devices digitally via a single USB or serial cable.
  • Distribute power to all devices with a single power source.
  • Multiple breakout boxes can be daisy-chained to control up to 26 instruments.
