Beckhoff EL1252-0050 | EtherCAT Terminal, 2-channel digital input, 5 V DC, 1 µs, timestamp

The EL1252-0050 digital input terminal acquires the fast binary 5 V control

signals from the process level and transmits them, in an electrically isolated

form, to the controller. The EtherCAT Terminal has two 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.

The switching thresholds of the input circuit are based on the CMOS level:

Signal voltage "0" < 0.8 V, signal voltage "1" > 2.4 V. The 5 V supply voltage

can be generated by the EL9505 power supply terminal and fed into the power

contacts.

Special features:

• 5 V inputs

• suitable for particularly fast signals due to very low input delay

• synchronized operation through distributed clocks XFC technology possible

• support of XFC technology timestamp
