Beckhoff EL1252 EtherCAT 2-channel Digital Input Terminal with Timestamp
The EL1252 digital input terminal is a controller with EtherCAT Terminals I/O systems, two channels, 24 V DC, 1 µs, with timestamp. It is widely used in Homag machines.
With this XFC technology, signal characteristics can be traced exactly in time and correlated with the distributed clocks system-wide.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
