Description
| EK1960-0000 | TwinSAFE Compact Controller for EtherCAT Terminals (ELxxxx) with integrated I/Os: – 20 safe digital inputs 24 V DC – 24 safe digital outputs 24 V DC, 2 A, 1-wire system safety protocol: TwinSAFE/Safety over EtherCAT connection: RJ45 |
The EK1960 TwinSAFE Compact Controller extends the range of applications of the TwinSAFE integrated safety solution. The core of the safety controller corresponds to the functionality of the EL6910 dedicated safety controller. Thanks to the compact design of the EK1960 with 20 safe digital inputs and 24 safe digital outputs (up to 2 A), it covers in particular the safety requirements of compact machines. The EK1960 can be operated "stand-alone" or networked with other controllers via the EtherCAT connectors. If the coupler is operated in an EtherCAT network, it can be extended by all EL/ES terminals like any EtherCAT coupler. As a stand-alone device, it cannot be extended by terminals.
The TwinSAFE Compact Controller is programmed via the TwinCAT Safety Editor in the same way as other TwinSAFE components. A TwinSAFE project is created and loaded over EtherCAT into the EK1960. The EK1960 supports the establishment of 128 TwinSAFE connections. For flexible adaptation to different safety tasks, the TwinSAFE Compact Controller can be combined with the TwinSAFE I/O components in IP20 and IP67 and the TwinSAFE Drive Option cards.
In addition to the Safety over EtherCAT protocol, the EK1960 also supports the TwinSAFE SC technology. This makes the safe transfer of data from TwinSAFE SC terminals to the EK1960 TwinSAFE Compact Controller possible.
The EK1960 also supports the processing of analog signals (16/32 bit, signed and unsigned). These signals can be transferred to the logic as standard, TwinSAFE SC or Safety over EtherCAT signals. Analog signals can thus be checked for plausibility within the logic.
Certified function blocks such as ADD, SUB, MUL, DIV, and also more complex ones such as Counter, Limit or Compare are available for the processing of analog signals.
