Installation Guidelines

• Ensure the PLC rack power is switched off prior to the physical installation of the module.
• Verify that the input signal voltage levels from field devices are compatible with the 24Vdc specification to prevent damage.
• Use shielded twisted-pair cabling for field inputs to reduce the impact of electromagnetic interference (EMI) on the digital signals.
• Ensure all terminal connections are firm and correctly mapped to the input channels configured in the controller software.
• Adhere to standard ESD (Electrostatic Discharge) protocols when handling the module to protect internal electronic components.
