Beckhoff EL1262-0050 | EtherCAT Terminal, 2-channel digital input, 5 V DC, 1 µs, oversampling

The EL1262-0050 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 sampled with a configurable, integer multiple

(oversampling factor: n) of the bus cycle frequency (n microcycles

per bus cycle). For each bus cycle, the EtherCAT Terminal generates

a process data block that is transferred collectively during the next

bus cycle. The timebase of the terminal can be synchronized precisely

with other EtherCAT devices via distributed clocks.

This XFC procedure enables the temporal resolution of the digital input

signals to be increased to n times the bus cycle time. 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

• multiple sampling of a process data through oversampling
