EL2258 | 8-channel digital output terminal with multi-timestamping
The 8-channel EL2258 digital output terminal switches the binary output signals of the controller electrically isolated from the process level. As in the EL2252, the outputs of the EL2258 are switched with high precision relative to the transferred timestamp, although there are certain differences in the details: eight instead of two channels, coarser temporal resolution and AutoActivation, which enables consecutive switching tasks in each cycle. With multi-timestamping as many events can be read per channel in each EtherCAT cycle, as were pre-loaded in the internal buffer.
The distributed clocks are used as time reference. In conjunction with timestamp input terminals, the EL2258 enables responses at equidistant intervals that are largely independent of the bus cycle time.
