EL2202 - Introduction
2 channel digital output terminal, 24 VDC, TON/TOFF 1 μs, push-pull outputs with tristate
The EL2202 digital output terminal connects the binary control signals from the automation device on to the actuators at the process level with electrical isolation. This terminal benefits from very small output delay and is therefore suitable for signals requiring particularly fast output. The EtherCAT terminal supports distributed clocks, i.e. the output data can be monitored synchronous with other data from terminals with distributed clock support. The accuracy across the system is <<1 µs. The EtherCAT terminal has a push-pull output that enables the output to be connected actively to 24 V, 0 V or high-resistance. The EL2202 contains 2 channels, the signal state of which is indicated via LEDs. The state "high-resistance" (tristate) is indicated through a further LED for each channel.
The EL2202 can be used in 2 operating modes that can be changed online via the Beckhoff TwinCAT System Manager:
- EL2202-0000 The outputs are switched as soon as the EtherCAT frame supplying process data was verified as valid.
- EL2202-0100 The outputs are cyclically switched through SYNC0 that runs synchronous with the task that supplies the EL2202-0100 with process data.
The delivery state is EL2202-0000.
