EL2262 - Introduction
Two-channel digital output terminal 24 VDC, with oversampling
The EL2262 digital output terminal connects the binary control output signals at the process level with electrical isolation. The outputs are controlled with an adjustable integral multiple (oversampling factor: n) of the bus cycle time (n microcycles per bus cycle). For each micro-cycle, the EtherCAT Terminal receives a process data block that is output consecutively. The time base of the terminal can be synchronized precisely with other EtherCAT devices via distributed clocks. An output pattern with a significantly higher pulse sequence than the bus cycle time is thus output precisely with the system-wide timebase. This procedure enables the temporal resolution of the digital output signals to be increased to n times the bus cycle time. The maximum output rate is 1 Msamples/s.
The EL2262 supports distributed clocks, i.e. the output data can be synchronously output with other data that are similarly connected, distributed, to distributed clock terminals. The accuracy across the system is < 100 ns.
The EL2262 can operate up to two channels with identical oversampling factor. To reduce process data traffic channel 1 can be operated solely.
