Products in Omron’s E5_C temperature controller family reduce set-up time and provide process control that is faster, more accurate and more responsive. Key features of the range include Omron’s high-stability PID control system and high-contrast displays that are easily readable, even in poor lighting conditions.
The family is complemented by a programmable T-type controller, which allows users to design their own temperature curve by setting up to 32 different programme profiles that can contain a total of 255 segments. To cater for changing process conditions, auto-tuning can be executed automatically in every sub-segment to optimise control performance. Ramp-up, ramp-down and soak functions make the controllers a versatile choice for a wide range of process applications.
“A major design goal for controllers in the E5_C range was to make the setting of PID parameters as easy as possible,” says Victor Marques, general manager Omron Electronics South Africa. “Our patented ‘tune-and-go’ PID control algorithm allows users to optimise controller behaviour to suit their specific applications with the aid of a simple software tool, so that overshoot is minimised and maximum stability is achieved. The algorithm manages changes in ambient and process conditions, improving both machine availability and product quality.”
Web server functionality makes remote access possible via the Internet for diagnosis and maintenance using Omron NB touchscreen terminals, which also support data logging, for example on a USB stick. Web-based parametric selectors help users to choose the right controllers and temperature sensors for their application, and the Omron sales team provides support at every project stage to ensure that machines are up and running as quickly as possible.
All models are provided with five front panel keys that can be used for routine operation and, in most applications, for set up. For demanding applications where additional flexibility is needed, Omron’s intuitive PC-based CX-Thermo software offers fast parameterisation, rapid device adjustment and simplified maintenance. The CX-Thermo software can also be used to capture data from E5_C controllers so that temperature/time curves can be generated.
