BECKHOFF EL2212

The EL2212 digital output terminal connects the binary control signals from the automation unit on to the actuators at the process level with electrical isolation. With multi-timestamping as many events can be read per channel in each EtherCAT cycle, as were pre-loaded in the internal buffer.
The EL2212 supports particularly fast switching of inductive loads, such as valves or relays. 24…72 V 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 the current channel-wise in order to protect the load. The switch-off process is also accelerated considerably by the pole reversal of the voltage. Both channels can be activated independently of each other.
