Pulse Measurement and Channel Functions
The DFI 01 acquires and preprocesses pulse signals for control-system applications. Depending on the configured function, the module can support event counting, frequency measurement, period measurement, pulse-width measurement and dosing circuits. These functions allow the controller to use pulse-based field signals for monitoring and process control.
Each of the four channels includes one counter input, two digital control inputs and two digital control outputs. The outputs require an external power supply. The counter input, control inputs and control outputs also have electrical isolation from one another within each channel.
