Introduction
Moxa’s 4500 Series ioThinx modules (45MR) are available with DI/Os, AIs, relays, RTDs and other I/O types, giving users a wide range of options and allowing them to select the I/O combination that best suits their target application. Thanks to the unique mechanical design, the hardware can be easily installed and removed without tools, significantly reducing the time required to set up and replace the modules.

Easy tool-free installation and removal
The ioThinx 4500 series has a unique mechanical design that reduces the time required for installation and removal. Screwdrivers and other tools are not required for any part of the hardware installation, including mounting the device on a DIN rail and connecting the wiring for communication and I/O signal acquisition. No tools are required to remove the ioThinx from a DIN rail either. Removing all modules from a DIN rail is also easy with the help of the locking and unlocking tab.
