Installing Analog 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. Installing or removing modules with power applied can destroy the
module.
Each position on an analog mounting rack can accept either an input or an output module. Install
the I/O module that performs the required function. Secure the module with the captive
Phillips-head screw. Refer to the module’s data sheet for detailed specifications and wiring diagrams
for each analog I/O module.
