EL1252-0010 | EtherCAT Terminal, 2-channel digital input, 24 V DC, 10 µs, timestamp

The EL1252-0010 digital input terminal acquires the fast binary 24 V control signals from the process level and transmits them, in an electrically isolated form, to the controller. The EtherCAT Terminal contains two channels whose signal state is indicated by LEDs. The signals are furnished with a time stamp that identifies the time of the last edge change with a resolution of 1 ns. With this XFC technology, signal characteristics can be traced exactly in time and correlated with the distributed clocks system-wide. With this technology, machine-wide parallel hardware wiring of digital inputs or encoder signals for synchronization purposes is often no longer required. In conjunction with the EL2252 EtherCAT Terminal (digital output terminal with time stamp), the EL1252-0010 enables responses with equidistant time intervals, largely independent of the bus cycle time.

Special features:

• suitable for particularly fast signals due to very low input delay
• synchronized operation through distributed clocks XFC technology possible
• support of XFC technology timestamp
• detection of fast edges with simultaneous filtering out of short interferences by 10 µs input filter (cf. EL1252: 1 µs)
