Installation Guidelines
The IT42 module is designed to be mounted directly onto the CPU module (PM4, PM5, or PM6).
A maximum of two expansion modules can be installed per CPU module.
Each IT42 module occupies one additional slot alongside the CPU module.
Ensure the system is powered down before inserting or removing any submodule to prevent electrical damage.
Binary I/O signals are typically routed via a 40-pin ribbon cable to interface modules, such as the SE3.1.
Follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect sensitive internal circuitry.
