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.
