Description: The new process controller, type 573, has options of two analogue inputs and an analogue output or two optocoupler outputs and can thus be used both in single channel mode as well as in dual channel. In dual channel mode, all arithmetic operations are available for displaying sum total, difference, ratio or the product. Inputs and outputs can be scaled separately. The type 573 process controller can be used as a simple process signal converter, process controller (On/Off controller) or for complex measuring tasks, where the relationship between two values, one to the other, must be monitored, calculated or further processed in a higher-level controller. Application areas include, for example, the monitoring of mixing ratios, the display of flow rate with material stretching. Other areas include the monitoring of synchronous operation and display of individual speeds as well as level monitoring and adjustment and the display of inflow and outflow.
