Introduction
16-channel digital input module, 24 VDC, filter 1 µs, timestamping
The EJ1254 digital input module acquires the fast binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the controller.
The EtherCAT plug-in module has four channels that indicate their signal state via light emitting diodes.
The signals are furnished with a time stamp that identifies the time of the last edge change with a resolution of 1 ns. With this XFC technology, signal characteristics can be traced exactly in time and correlated with the distributed clocks system-wide. With this technology, machine-wide parallel hardware wiring of digital inputs or encoder signals for synchronization purposes is often no longer required.
