EL1258
EL1258 | 8-channel digital input terminal with multi-timestamping
The 8-channel digital input terminal EL1258 acquires fast binary control signals from the process level and transmits them electrically isolated to the controller. In comparison with the EL1252, the EL1258 not only offers a higher channel density, but thanks to the multi-timestamping function also a higher performance. Whereas the EL1252 can accept one edge change with timestamp per bus cycle, the EL1258 offers the possibility to register up to 32 events with timestamps. The reduced timestamp width of 32 bits, which corresponds to a resolution of 4.29 seconds, does not result in functional restrictions for most applications. Through the distributed clocks system, the EL1258 is synchronised with other EtherCAT devices, so that events in the whole system will be measured with a uniform time base.
