BRX remote I/O controllers are ideal for systems where components are separated by large distances or where an extreme amount of I/O is needed. With these controllers, remote I/O can be located separately from the CPU and linked through Ethernet, Modbus RTU, or Modbus TCP communication.

Remote I/O Controllers
BRX remote I/O controllers serve as the communication interface between distributed BRX I/O modules and the host control system. Supporting native Do‑more remote I/O, DirectLOGIC Ethernet remote I/O, and Modbus‑based applications, these controllers manage the exchange of I/O data between remote field devices and the PLC or master controller. Each unit supports up to eight BRX I/O expansion modules and is designed for seamless integration into a wide range of automation system architectures.

Do-more I/O Controllers (DMIO)
BRX Do-more I/O controllers provide distributed I/O throughout a facility by connecting remote BRX I/O modules to Do-more PLCs over Ethernet. Installed near the equipment they serve, remote I/O racks communicate with the host PLC through a single network connection using the Do-more Ethernet Remote I/O protocol. When stacked with BRX remote I/O modules, they form a shared backplane and communicate via the system bus. Remote I/O systems are automatically discovered and treated as native I/O, enabling fast configuration and seamless integration with the control system.
- Compatible with BX-DM1E, H2-DM1E, and T1H-DM1E CPUs
- Up to 8 expansion modules per rack
- Up to 16 remote I/O racks per Do-more CPU
- Built-in 10/100 Mbps Ethernet port
- Available in 120–240 VAC and 12–24 VDC powered models
- AC-powered models include an integrated 24 VDC auxiliary power supply
- Embedded HTTP web server provides access to system status and diagnostic information

Ethernet Base Controllers (EBC100)
BRX Ethernet Base Controllers (EBC100) provide Ethernet-based remote I/O expansion for DirectLOGIC PLC systems, Do-more PLC systems, and Modbus TCP applications. They allow remote I/O racks to be installed near field devices and communicate back to the host system over a single Ethernet connection. Depending on the protocol used, I/O data can appear as native system I/O or be accessed through standard Modbus TCP read and write instructions. This enables flexible integration of distributed I/O across both legacy and modern control platforms.
- Supports Do-more Ethernet Remote I/O, Host Ethernet Remote I/O, and Modbus TCP server communications
- Compatible with BX-DM1E, H2-DM1E, and T1H-DM1E CPUs, as well as H2-ERM100 and H4-ERM100 systems
- Up to 8 expansion modules per rack
- Up to 16 EBC100 remote I/O racks supported for Do-more or DirectLOGIC systems
- Up to 247 remote I/O racks supported for Modbus TCP applications
- Built-in 10/100 Mbps Ethernet port
- Available in 120–240 VAC and 12–24 VDC powered models
- AC-powered models include an integrated 24 VDC auxiliary power supply
- Embedded HTTP web server provides access to system status and diagnostic information

Modbus I/O Controllers (MBIO)
BRX Modbus I/O slave controllers (MBIO) provide distributed I/O expansion for systems using Modbus RTU or Modbus TCP master devices. Remote BRX I/O modules connect to the controller and exchange I/O data with a host system using standard Modbus read and write instructions. This allows distributed I/O points to be mapped to Modbus registers for integration with PLCs and other control systems that support Modbus communications.
- Compatible with any Modbus RTU master or Modbus TCP client device
- Up to 8 expansion modules per rack
- Up to 31 remote I/O racks supported for Modbus RTU over RS-485
- Up to 247 remote I/O racks supported for Modbus TCP applications
- Built-in 10/100 Mbps Ethernet port
- Available in 120–240 VAC and 12–24 VDC powered models
- AC-powered models include an integrated 24 VDC auxiliary power supply
- Embedded HTTP web server provides access to system status and diagnostic information
