The EL2212 digital output terminal connects the binary control signals from the automation device on to the actuators at the process level with electrical isolation. The multi-timestamp features allow each EtherCAT cycle to capture as many events per channel as were preloaded in the internal buffer.

The EL2212 supports the particularly fast switching of inductive loads, such as valves or relays. 24 to 72 V DC supplies are connected to the power contacts and passed through to the load when switched on. After an adjustable waiting period the terminal begins to control channel-wise the current in order to protect the load. The switching process can be positioned exactly using the timestamp. The switch-off process is also accelerated considerably by the pole reversal of the voltage. The two channels are independently controllable.

Special features:

• Push-pull output with tristate
• Suitable for particularly fast switching of inductive loads e.g., valves or relays
• The outputs are current-controlled, with high-impedance switching option
• Synchronized operation through distributed clocks XFC technology possible
• High performance thanks to XFC multi-timestamp feature
