Processing discrete input: Use as a standard input module with filtering in the range of 24...125 Vdc.

Event time stamping: The event of an individual process status can be logged with the corresponding time (time stamp). Time stamping provides information that allows you to observe and evaluate the sequence of events in your process.

Counter value: Use as a standard I/O module (with filtering, 32-bit summing with maximum 500 Hz) with an input range of 24...125 Vdc.

Periodic time stamping of process values: Recording counter values in defined time intervals. The combined use of both function groups can be used as an advantage.

Time dependent switching actions: The input modules can be set regardless of time for controlling lighting, heating, ventilators, temperatures (building automation), or for opening/closing doors, and machines (safety measures). The output status can be recorded with the ERT.
