Technical Specifications

Installation Guidelines

• Ensure the PLC rack is powered down before inserting or removing the module to prevent electrical damage.
• Verify that the module is fully seated in the backplane slot and secured with the integrated locking mechanism.
• Use shielded twisted-pair cabling for analog signals to minimize electromagnetic interference (EMI) and noise.
• Maintain proper grounding practices for the cable shields at the control cabinet entry point.
• Ensure adequate ventilation around the rack to accommodate the 5 W power dissipation and prevent thermal throttling.
• Handle with care to prevent electrostatic discharge (ESD) damage to the internal circuitry.
