BECKHOFF EL1252

The EL1252 digital input terminal acquires the fast binary control signals from the process level and transmits them, in an electrically isolated form, to the controller. The signals are furnished with a timestamp that identifies the time of the last edge change with a resolution of 1 ns. This technology enables signals to be traced exactly over time and synchronised with the distributed clocks across the system. With this technology, machine-wide parallel hardware wiring of digital inputs or encoder signals for synchronisation purposes is often no longer required. In conjunction with the EL2252 EtherCAT Terminal (digital output terminal with timestamp), the EL1252 enables responses with equidistant time intervals, largely independent of the bus cycle time.
