Distributed Ethernet/IP I/O Module BL203 for KV-7000 PLC Compatible With EtherNet/IP Master
BL203 coupler is a data acquisition and control system based on a powerful 32-bit microprocessor design with Linux operating system and support for Ethernet/IP protocols, allowing quick access to Ethernet/IP-enabled PLCs in the field for IIoT and industrial automation applications.
The BL203 distributed I/O system consists of 3 parts: Coupler, I/O modules and terminal module.
The communication between the node and the field devices (eg PLC) takes place via the Ethernet interface of the fieldbus coupler, and the communication between the fieldbus coupler and the I/O modules takes place via the local bus. The two Ethernet interfaces are internally integrated with a switch function, which can establish a linear topology without the need for additional switches or hubs.
The system needs to use the power module to provide 24VDC system voltage and 24VDC field voltage. Since two independent power supplies are used, the field voltage input interface and system voltage input interface of BL203 coupler are electrically isolated from each other.
When assembling fieldbus node modules, each I/O module can be arranged in any combination, and it is not required to be grouped by module type.
A terminal module must be plugged into the end of a fieldbus node to ensure correct data transmission.
High reliability, easy expansion, easy setting, and convenient network wiring, these capabilities let users efficiently adapt the BL203 I/O system to a variety of complex industrial applications.
