The EL1262 digital input terminal 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 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.

Special features:

• 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
