Power & Communications for Multiple Alicat Instruments

Alicat’s BB3 multi-drop breakout boxes make building your own local flow control network easy. Control up to nine 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 BB3 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.



Connect your BB3-232 to a computer or PLC using one of the methods below.

  • USB 2.0 (USB A-B cable included)
  • RS-232 9-pin serial port (cable included)
  • Terminal block transmit and receive sockets (RX/TX)



Connected devices receive power from the BB3’s common power bus. Power connected at any point in the system is distributed to all devices.

  • Connect a PVPS24U power supply (not included) to the BB3’s barrel-type power jack or free wire power to the BB3’s terminal block power and ground sockets.
