EL1202 | EtherCAT Terminal, 2-channel digital input, 24 V DC, 1 µs
Distributed Clocks: the integrated time management system in EtherCAT
The EL1202 digital input terminal acquires the binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT Terminal contains two channels whose signal state is indicated by LEDs.
The EL1202 can support the XFC Distributed Clocks technology, i.e. the input data can be acquired synchronously with other data that are also connected in a distributed manner to Distributed Clock terminals. The system-wide DC accuracy is << 1 μs. To this end the user has to switch to terminal version EL1202-0100 (see documentation).
Special features:
- suitable for particularly fast signals due to very low input delay
- Ton/Toff <1 µs
- synchronized operation can be activated via distributed clocks XFC technology (EL1202-0100)
