The EL1202 digital input terminal acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the higher-level automation unit. It is suitable for particularly fast signals due to its very low input delay. The EtherCAT Terminal can support distributed clocks, i.e. the input data can be monitored synchronously with other data that are also linked to distributed clock terminals. To this end, the user has to switch to terminal version EL1202-0100 (see documentation). The DC accuracy across the system is << 1 µs. For this, the user has to switch the terminal to the EL1202-0100 version (see documentation). The EL1202 contains two channels whose signal state is indicated via LEDs.
