MLC 9000+

This product is now obsolete. Our recommended alternative is the KSVario system or contact our Support Team who can help you choose the right alternative to migrate your current MLC 9000+ application. 

The MLC 9000+ maximises up-time by offering a true hot-swap facility. A module can be removed, replaced, automatically re-configured and back in service in under 30 seconds. Unlike some systems, with the MLC9000+ there is no need to touch the remaining control modules - allowing them to continue functioning when any of the other modules are removed.

Communication module options currently include Modbus, DeviceNet, Profibus and Modbus/TCP. Control modules are available with 1, 3 and 4 loops. Heater break inputs are available on 1 and 3 loop modules.

The MLC 9000+ system provides a compact multi loop DIN-rail process control system. Even using a full complement of 8 control modules, providing up to 32 loops, the MLC9000+ still only measures 206mm wide making it the ideal choice when panel space is a concern.

  • Quicker to setpoint and faster reaction to process disturbances
  • On-demand and auto-tuning – no need to manually tune loops
  • Set-up 32 loops in less than 30 minutes
  • Only buy the loops required – no need to buy in multiples of four
  • Free up PLC capacity by ‘outsourcing’ loop control to the MLC 9000+
