URB-SER Unitronics Modbus RTU Network Adapter
MPN: URB-SER
Alt. SKU: URBSER
Why Choose the Unitronics URB-SER Remote I/O Serial Adapter?
The Unitronics URB-SER is a remote I/O Modbus Serial RTU adapter designed to extend PLC input and output capabilities across industrial automation networks. It enables distributed control architectures by connecting remote I/O modules to a PLC using reliable serial communication.
With the URB-SER adapter, engineers can place input and output modules close to sensors, actuators and field devices instead of routing all wiring back to a central control cabinet. This approach simplifies installation, reduces wiring complexity and improves system scalability in large machines or production lines.
The module communicates using the widely adopted Modbus RTU protocol over serial communication and supports up to 63 remote I/O modules, making it suitable for distributed industrial automation systems requiring flexible expansion.
