Multi-loop temperature controllers manage several zones simultaneously to stabilize the temperature of environments such as ovens, packaging, and heat treatment.
About Multi-loop Temp Controller
Generally, behind panel, multi-loop controllers support various fieldbus options allowing for easy integration with other devices within the machine or a wider plant network. Multi–loop systems can be programmed to allow the zones to be independent or to work in conjunction with one another, depending on the needs of the application. Benefits of the multi–loop temperature controller include reduced installation costs, improved integration, and minimal machine downtime.
Multi-loop controllers are generally mounted behind the panel, as opposed to single-loop controllers which are often front panel mounted. Proprietary software for PCs is most often used to program and download settings to the multi-loop temperature controller.
West Control Solutions offers a range of controllers from its leading product brands, CAL, Partlow, PMA, and West. These meet a variety of differing control loop requirements as well as provide different degrees of functionality. The chart below presents a selection of our most popular multi-loop temperature and process controllers.
Descriptions of West Control Solutions MLC 9000+Multi-loop Temp Controller
The MLC 9000+ maximizes 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.
Benefits & Features of MLC 9000+Multi-loop Temp Controller
- 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+
