AKT2G-AT-425-000
Four-channel analog output terminals, -10..+10 V, 12 bit
The AKT2G-AT-425 Analog Output Terminal generates signals in the range from -10 V to +10 V. The voltage is supplied to the process level with a resolution of 12 bits, and is electrically isolated. The output channels of an EtherCAT***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs Terminal have a common ground potential. The output stages are powered by the 24 V supply. The signal state of the EtherCAT Terminals is indicated by light emitting diodes. The AT-425 supports distributed clocks, i.e. the input data can be monitored synchronously with other data that are also linked to distributed clock terminals. The accuracy across the system is < 100 ns.

This LED indicates the terminal's operating state: |
|
off |
State of the EtherCAT State Machine: INIT = initialization of the terminal, state of the EtherCAT State Machine: BOOTSTRAP = function for firmware updates of the terminal |
||
flashing |
State of the EtherCAT State Machine: PREOP = function for mailbox communication and different standard-settings set |
||
single flash |
State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks. Outputs remain in safe state |
||
on |
State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible |
If several RUN LEDs are present, all of them have the same function.
