![EL1258 | EtherCAT Terminal, 8-channel digital input, 24 V DC, 1 µs, multi-timestamp](https://multimedia.beckhoff.com/media/el1258__web_preview.png)
The EL1258 digital input terminal acquires the fast binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. Each EtherCAT Terminal has eight channels that indicate their signal state via light emitting diodes. In comparison with the EL1252, the EL1258 offers not only a higher channel density, but also a higher performance thanks to the XFC multi-timestamp function. Whereas the EL1252 can accept one edge change with time stamp per bus cycle, the EL1258 offers the possibility to register up to 32 events with time stamps. The EL1258 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.
Special features:
- suitable for particularly fast signals due to very low input delay
- synchronized operation through distributed clocks XFC technology possible
- high performance thanks to XFC multi-timestamp feature
Product status:
regular delivery
