ControlAir Inc. announces the introduction of the Type 5500 Multi-station , Digital-to-Pneumatic Pressure Regulator with DeviceNet™. This unique 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™ communication protocol.

An 8-bit digital signal describing the required output pressure for each electronic regulator is sent by DeviceNet™ to the Type 5500 node. The Type 5500 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. Each manifold requires only one power cord and one fieldbus connection for up to 8 pressure outputs from one node. This simplified system greatly reduces set up time and wiring costs associated with other analog I/P Transducers. An optional pressure sensor feeds back a diagnostic signal by DeviceNet™ to the controller, which then monitors pressure output from each I/P. Individual pneumatic shutoff valves allow adding, changing or removing electronic pressure regulators without shutting off the main air supply. It also allows servicing one station while the others remain in operation.

In addition to delivering low hysteresis and excellent repeatability, the Type 5500 has RFI/EMI Effect protection. Output ranges include 3-15 psig, 3-27 psig, 6-30 psig, 2-60 psig and 3-120 psig. Maximum supply pressure is 150 psig. Temperature limits range from -20º F to 150º F. Built-in volume boosters provide flow capacity of up to 20 scfm. Mounting is available as wall or DIN Rail.

Applications include modulated control of valves, cylinders and actuators for machine tools, robotics, food and drug processing, semiconductor, textiles, medical diagnostic, material handling, test and assembly, pulp and paper, printing presses, tire production and material handling.
