This multi-station manifold uses a common air supply to provide electronic proportional control of output pressure from any combination of 4, 6, or 8 station units through the use of a DeviceNet™ or Profibus™ communication network. An 8-bit digital signal describing the required output pressure for each electronic regulator is sent by DeviceNet™ or Profibus™ to the T5500 node. The T5500 converts the digital signal into the appropriate 4-20mA signal that is sent to each corresponding I/P transducer which adjusts output pressure to the desired setting. An optional pressure sensor feeds back a diagnostic signal by DeviceNet™ or Profibus™ to the controller, which then monitors pressure output from each I/P.
