AutomationDirect has added several new modules to the BRX PLC lineup. These modules include options rated for higher voltage systems, modules that expand communication options, or models that provide more diagnostics options than previous versions. All of the new modules are pluggable, making them simple to integrate with existing BRX hardware.

AutomationDirect BRX PLCs
The BRX PLC system is an industry-ready controller set that straddles the line between PLC and microcontroller. They can be programmed using the free DoMore software, which allows for motion control and advanced commands. Furthermore, the software includes a simulation mode so that programs can be tested before being deployed to running hardware systems. Designed with Industry 4.0 and the Industrial Internet of Things (IIoT), the BRX PLC can use MQTT, FTP, and HTTP(S) protocols.
Up to 36 discrete, high-speed I/O ports, expandable with additional I/O modules, are integrated into the PLC. Temperature, discrete, and analog I/O modules are available in various port counts.
Communications are possible through hot-swappable communications ports or through a built-in serial or Ethernet port. Also, internal RAM and microSD cards can be used for data logging at the PLC. This way, local copies of the data are stored in case of a communications interruption or for advanced troubleshooting.
Another neat feature of the BRX PLC is its price point. Controllers start out at under $300 and require no expensive software; just the free DoMore suite. The PLCs are built to be highly customizable, and machine builders and automation system designers can appreciate their flexibility and scalability at a low cost.

DC I/O Expansion Modules
The latest BRX PLC modules include expanded I/O capability and flexibility for higher voltage control systems. For instance, a new, 16-channel discrete output channel module means more devices can be controlled without needing a larger physical space. The module can deliver 12 to 24 VDC and be a good fit for many existing automation systems.
For higher voltage applications, there are also 16-channel input and output modules that can handle up to 48 VDC. AutomationDirect has also released a split module with eight input and eight output channels, which is suitable when a new feature or small control loop is added to an existing automation system.

Ethernet Pluggable Option Modules (POMs)
Enhanced communication for the BRX PLCs is possible through AutomationDirect’s new, hot-swappable comm ports, available in USB-C, Sparkplug B, or OPC UA, the BRX PLC can now communicate with even more hardware components. Dedicated connectivity is now possible for more systems, increasing the flexibility of the BRX PLC.
Customizable, Cost-Effective Control
All of AutomationDirect’s new modules (DC I/O and POMs) have built-in protections one would expect from a PLC module. They have onboard diagnostics for broken wires (open circuit), overcurrent (short circuit), and over-temperature conditions.
The new modules are designed to expand BRX PLC capabilities in a range of systems. For example, the ability to handle 48 V DC control signals makes the newest BRX modules a good fit for data centers and certain telecom operations. Historically, the telecom industry has used 48 V DC signals extensively, so rather than performing many conversions, the BRX can be integrated directly into these systems.
