£225.75
The Unitronics URB-TCP is a high-performance Ethernet Remote I/O Adapter designed to extend UniStream automation systems through distributed I/O architecture. As part of the advanced Unitronics URB Remote I/O platform, the URB-TCP enables remote installation of I/O modules over industrial Ethernet networks, helping reduce wiring complexity, lower installation costs and improve system scalability.
Designed specifically for Unitronics UniStream controllers, the URB-TCP acts as the communication gateway between the PLC and remote URB I/O modules. Its Ethernet-based architecture provides fast and reliable communication while allowing I/O to be located closer to sensors, actuators and field devices throughout industrial facilities.
Supporting up to 63 URB Remote I/O modules per adapter, the URB-TCP provides a flexible and scalable solution for machine builders, OEM manufacturers and industrial automation engineers. Dual Ethernet ports allow daisy-chain networking and simplified system expansion for demanding industrial applications.
The Unitronics URB-TCP enables engineers to install remote I/O modules closer to field devices while maintaining reliable Ethernet communication with the main controller. This architecture significantly reduces wiring requirements, simplifies installation and improves system maintainability.
Each adapter includes dual Ethernet ports, allowing multiple remote I/O stations to be linked together within a UniStream automation system. Up to eight remote I/O adapters can be connected to a single UniStream controller, providing extensive expansion capabilities for larger industrial applications.
