This 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 a resistance thermometer, a thermocouple and standard signals (current, voltage); linearizations of more than 20 sensors are stored. All instruments are fitted with two relay outputs. Types 702072 and 702074 have a binary input and a logic output; with type 702071, binary input and logic output are available alternatively (configurable). All controllers can also be extended by an optional output, which can be implemented as a relay output or as 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.
Electrical connection is at the rear, via screw terminals (pluggable terminal strips).
