PD 621 Digital I/O Module, application notesFeature overviewThe PD 621 contains 6 channels, each of which can be independently configured as a digital input or a digital output. Because of local intelligence within the PD 621, each input or output channel offers advanced functionality. These functions are integrated into the module itself and only need to be configured for operation, and no additional programming is needed. In fact, these unique functions can save a great deal of programming effort. Since the functions and safety monitors are embedded in the module, they execute independently of external controllers. This ensures safety, ultra fast response and independence from system reaction time.
All PROCES-DATA modules are based on the channel concept. A channel is a functional object, consisting of both functions and all function related data.
A PD 621 Module consists of 2 channel types.
