Introduction

EtherCAT plug-in module, 4-channel digital input, 24 V DC, 1 µs, timestamp

The EJ1254 digital input module acquires 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 timestamp that identifies the time of the last edge change with a resolution of 1 ns. With this XFC technology, signal curves 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.
