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.

EL1259 | 8-channel digital input + 8-channel digital output with multi-timestamping

The 16-channel EL1259 digital EtherCAT Terminal combines the function of the EL1258 – eight multi-timestamping inputs – with those of the EL2258 – eight multi-timestamping outputs. The high channel density in conjunction with timestamping of the signals enables fast, efficient processes through optimised sensor and actuator control. The EL1259 is also synchronised with other devices through the distributed clocks system, so that events in the whole system can be measured with a uniform timebase. The combination of DC-switched inputs and outputs within one terminal can be used for local switching tasks.
