The 8-channel digital input terminal EL1258-0010 acquires fast binary control signals from the process level and transmits them, in an electrically isolated form, to the controller. The EL1258-0010 is the ground switching version of the EL1258 and offers not only a higher channel density compared to the EL1252, but also higher performance due to the multi-timestamp function. Whereas the EL1252 can accept one edge change with timestamp per bus cycle, the EL1258-0010 offers the possibility to register up to 32 events with timestamps. The reduced timestamp width of 32 bits, which is equivalent to a resolution of 4.29 seconds, does not represent a functional limitation for most applications. The EL1258-0010 is synchronized with other EtherCAT devices through the distributed clocks system, so that events in the whole system can be measured with a uniform timebase.
