The PortBrain is a USB adapter board for easily adding digital I/O and analog inputs to any project. It can also operate in stand-alone mode as a simple PLC (Programmable Logic Controller).

Key Features:

• 24 individually programmable digital inputs/outputs.
• 5 analog inputs, including 1 built-in temperature sensor (thermistor). External sensors can be connected.
• Relay adapter available for controlling motors, other devices (see below).
• Interfaces to PC or Mac as a virtual COM port.
• Windows software for easy setup, monitoring and programming.
• Field-upgradable firmware.

Multi-OS Compatibility

Works with Mac, PC and Linux. Installs as a "virtual" serial port which works with most any programming language.

Windows Software

Using the software it is easy to configure the PortBrain and monitor the status of all the I/O pins. You can also edit and debug PCL programs.

Use With Your Own Software

You can easily integrate the PortBrain into your software -- you just need to send a few simple commands to the PortBrain as you would any other other serial device. A DLL (dynamic link library) is also available.

PLC Mode

In PLC (Programmable Logic Controller) mode, the PortBrain can be programmed to automatically turn outputs on/off depending a variety of conditions, including: temperature or almost any combination of input or other output states. Once programmed, the PortBrain can be disconnected from the PC and it will operate in "stand-alone" mode (power must still be provided of course!).
