Installation Guidelines
Ensure the control system is powered down before inserting or removing the module from the S100 I/O rack.
Handle the module using ESD-safe practices to prevent damage to sensitive electronic components.
Ensure proper grounding of the S100 I/O rack to minimize EMI interference.
Route signal cables away from high-voltage power lines and high-EMI sources to maintain signal accuracy.
Verify that the 24 V DC power supply is within the specified 19.2–30 V DC range before energizing.
Each group of 16 channels shares a common 0 V reference; consider external fusing for sub-group protection if required by the application.
