EL1144 | 4-channel digital input terminal 12 V DC

The EL1144 digital input terminal acquires the binary control signals and transmits them, in an electrically isolated form, to the higher-level automation unit. The EtherCAT Terminal contains four channels that indicate their signal state by means of light emitting diodes.

EL1202 | 2-channel digital input terminal 24 V DC, TON/TOFF 1 µs

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.

EL1252 | 2-channel digital input terminal with timestamping

The EL1252 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 furnished with a timestamp that identifies the time of the last edge change with a resolution of 1 ns. This technology enables signals to be traced exactly over time and synchronised with the distributed clocks across the system. With this technology, machine-wide parallel hardware wiring of digital inputs or encoder signals for synchronisation purposes is often no longer required. In conjunction with the EL2252 EtherCAT Terminal (digital output terminal with timestamp), the EL1252 enables responses with equidistant time intervals, largely independent of the bus cycle time.
