• Renewable Energy: Manages pitch control systems in wind turbines and solar tracking systems.

Technical Specifications

Installation Guidelines

• ESD Precautions: Always use a grounded wrist strap when handling the module to prevent electrostatic discharge damage to internal components.
• Power Down: Ensure the PLC rack power supply is switched off before inserting or removing the CPU module.
• Seating: Ensure the module is fully seated in the designated slot and that the locking tabs are engaged to maintain a secure connection to the backplane.
• Cable Routing: Route Ethernet communication cables away from high-voltage power lines and sources of electromagnetic interference (EMI) to ensure signal integrity.
• Battery Backup: For extended memory retention (up to 15 months), install the optional IC693ACC302 external battery.
