Ethernet coupler TRS-CAT

EtherCATfieldbusI/O

Tpa couplers allow you to connect the expansion modules to the implemented fieldbuses. Each device has 16 digital I/O lines at 24 V (short-circuit proof, LED signals), so that the cost of the node is better amortized. You will also find custom couplers in this section, designed and developed to make specific devices interface with different fieldbuses, such as solenoid valve blocks, for instance. Two LAN cables with the EtherCAT logo EtherCAT is an Ethernet-based, real-time communication technology, especially suited for communication between control systems and peripherals, like I/O systems, sensors, and drives. EtherCAT makes it possible to use Ethernet in the industrial automation field, as it grants short updating times, low communication jitter, and a low price. EtherCAT can optimize the network performance thanks to all the different network slave-devices directly processing the frame on the fly. Using the Distributed Clock allows us to synchronize all the secondary devices with a jitter lower than 1 μs. As for the interface towards the applications, EtherCAT can use the protocols CoE (CANopen over EtherCAT), SoE (SERCOS over EtherCAT), FoE (File Access over EtherCAT), and EoE (Ethernet over EtherCAT), so to guarantee compatibility with the most common real-time fieldbus technologies and with the standard Ethernet ones, such as TCP/IP, UDP/IP, or FTP. The coupler TRS-CAT allows you to connect an EtherCAT bus to a TRS bus and it can be mounted on DIN rails. TRS-CAT is a complex slave device (bus coupler) as determined by ETG specifications. TRS-CAT includes 16 bidirectional digital I/O lines; each is configurable either as input or output.
