EL2252 | EtherCAT Terminal, 2-channel digital output, 24 V DC, 0.5 A, timestamp
EtherCAT timestamp: high-precision interaction of controller and environment – to the exact nanosecond
Distributed Clocks: the integrated time management system in EtherCAT
Decentralised, end-to-end system synchronisation: With Distributed Clocks and EtherCAT.
The EL2252 digital output terminal connects the binary control output signals at the process level with electrical isolation. The outputs of the EtherCAT Terminal are switched with high precision to match the transferred timestamp, which has a resolution of 10 ns. This technology enables output switching times to be specified precisely across the system. The distributed clocks are used for reference. In conjunction with the EL1252 (digital input terminal with time stamp), the EL2252 enables responses with equidistant time intervals, largely independent of the bus cycle time. Each output can be switched to high resistance individually.
Special features:
- push-pull output with tristate
- high-impedance output switching option
- synchronized operation through distributed clocks XFC technology possible
- support of XFC technology timestamp
