Universal controller PMA KS45
The PMA KS45 is suitable for precise control tasks in all areas of industry. You can choose between simple on/off control, PID control and motor step control. The actual value signal is connected via a universal input. A second analog input can be used for heating current measurement or as an external setpoint input. A PMA KS45 has at least one universal input and two switching outputs. The universal controller can optionally be equipped with a universal output or with optocoupler outputs. The universal output can be configured as a continuous output with current or voltage, for controlling solid state relays or for powering transmitters. There is galvanic isolation between inputs and outputs, as well as to the auxiliary power and to the communication interfaces.
The controller is ideal for use in the following applications:
- Oven, burner and boiler
- Heat treatment plants
- Dryers and climate chambers
- Plastics processing
- Sterilizers
- Oxygen applications

Operation and display
The two-line LCD display allows the measured values to be displayed and the device to be fully operated. The two-color LED and 4 additional display elements reliably indicate the operating status, operating mode and error messages. The unit of the measured variable is shown in the display and can also be defined on a customer-specific basis. The extended operating level is used to display any signals and parameters in the 2nd display line.
Interface and engineering tool
Settings can be made via the front panel as well as via the Blue-Port® front interface and the BlueControl® software. The PMA KS45 can exchange data with higher-level control systems and PCs via the optional RS 485 interface with MODBUS-RTU protocol, which is installed in the top-hat rail. Devices with the system interface option are connected to fieldbuses via a bus coupler
