FX18 I/O Expander

The FX18 is a low voltage I/O expansion controller designed to work with the BAC. There are an additional 16 I/O ports. There are two high output ports, which can be used to provide up to 2A of output current. The FX18 communicates to the BAC V using an FX45 using I2C. As an added bonus, there is a High-Drive I2C terminal onboard, allowing the FX18 to be a considerable distance from the BAC & FX45 without requiring an additional FX14! The FX18 is an affordable choice that's particularly well suited for interfacing with low-voltage external devices, like third party relay boards or microcontrollers, or for working with arrays of small switches or buttons.  If you are looking for additional industrial-hardened outputs comparable to those found on the BAC, you may find the FX60 to be a better fit for your needs. Note that we are currently out of stock of the plastic cases pictured, so FX18 modules ordered will arrive as a bare circuit board.  This does not affect the functionality of
