Installing Digital I/O Modules
CAUTION: Be sure that all Optomux unit power and power to the controlled devices is removed before
installing or removing I/O modules. Each position on a digital mounting rack can accept either input or
output modules. Install the color-coded I/O modules on the IO mounting rack by inserting the module pins
in the sockets on the rack. Secure the modules with the captive Phillips-head screw.
Each power I/O module is connected to two barrier strip terminals on the I/O mounting rack. When
connecting DC loads or input, the lower-numbered terminal is always more positive.
For detailed information concerning module specifications and wiring, refer to the module data
sheets. Digital Optomux units only accept modules with 5-volt logic (for example, IDC5).
Each digital I/O mounting rack is supplied with an individual 5-amp fuse for each module position.
The fuse is installed in a pair of sockets and may be removed with needle-nose pliers.
