Identification : Kid, Metacentre DC02, DC03 & DC04Part number : Refer to Product guide / price list for specific part number or contact dealer
Product Family : Metacentre
Function : Central management control & monitoring of air / gas compressor Optional integrated control / monitoring of ancillary compressed air equipment
Definition : Narrow pressure band controller with enhanced software features & functions
Capacity : 2, 3 or 4 air / gas compressors & Metacentre ancillary product control / monitoring via optional Metacentre I/O & sensor options
Compressor connectivity : DCO Series terminal board & dedicated compressor interface or via airbus communication protocol
Supported protocol : Airbus & Modbus RTU via dedicated network gateway
Software : Pre-programmed application software, configurable via password protected operator interface
Product overview : As demand for compressed air fluctuates and as system pressure decays or increases in response to that demand, metacentre compressor management system ensure that site wide compressors and ancillary compressed air equipment are harnessed as 1 to obtain an equilibrium where efficiency, equipment utilisation and system pressure are in perfect balance. In unmanaged compressed air systems that equilibrium represents a significant energy & cost saving opportunity.

Metacentre DCO is a specialised supervisory control product designed to provide energy efficient optimised narrow pressure and priority management control of up to 4 air / gas compressors operating in a common compressed air / gas system. Each DCO kit is provided with a quantity of compressor interface PCB’s (mi-PCB) and a 4-20mA / 0-16 bar pressure sensor.
