EL1262 - Introduction
2-channel digital input terminal with oversampling
The EL1262 digital input terminal acquires the fast binary control signals from the process level and transmits them, in an electrically isolated form, to the controller. The signals are sampled with a configurable, integer multiple (oversampling factor: n) of the bus cycle time (n microcycles per bus cycle). For each microcycle, the EtherCAT Terminal generates a process data block that is transferred collectively during the next bus cycle. The time base of the terminal can be synchronized precisely with other EtherCAT devices via distributed clocks. This procedure enables the temporal resolution of the acquisition of the digital input signals to be increased to n times the bus cycle time.
The EL1262-0050 offers a version with 5 V input voltage (TTL level) and 5 V supply voltage.
