The JUMO cTRON series is a new family of universal compact PID controllers for controlling temperature, pressure and other variables. The attractive design of the controller, combined with its ergonomically shaped, ultra-flat front panel, will set any machine or control panel distinctively apart from the competition. One universal and 2 binary inputs, two relay outputs, a 0/12V logic output, a timer function, ramp function, and auto-tuning are standard on each unit. An additional relay output and RS422/485 communication are available.
The JUMO cTRON (70.2070) is a series of controllers consists of three, freely configurable and universally applicable compact controllers in various DIN formats for controlling temperature, pressure and other process variables. The main areas of application are heating cabinets, temperature stabilizing and cooling systems, drying and freezing systems and laboratory furnaces and sterilizers in the food, plastics and packaging industries.
With all models, one red and one green seven-segment LED display are used to display process values and parameters. There are a further seven LEDs available to display switch positions, manual mode, ramp function and timer mode. Operation is by four keys on the front panel.
Depending on the hardware configuration, the instruments can be used as 2-state controllers, 3-state controllers, modulating controllers or continuous controllers. Self-optimization, ramp function with adjustable gradients, manual mode, power ON delay, two limit comparators, extensive timer functions and a service counter are included, even in the basic version.
Each instrument has a universal measurement input for an RTD temperature probe, a thermocouple and standard signals (current, voltage); linearizations of more than 20 sensors are stored. All types are equipped with at maximum two binary inputs, one logic output and two relay outputs. In addition every type can optionally be delivered with a third relay output or an analog output.
A setup interface is available as standard for configuration with the setup program (option). The instruments can be integrated into a data network (Modbus) via an optional RS485 interface.
