Technical Specifications

Installation Guidelines

• Ensure the PLC rack is powered down before inserting or removing the CPU module to prevent electrical damage.
• The module occupies a single slot in the Series 90-70 backplane; ensure it is fully seated and the retaining screws are tightened to maintain a secure connection.
• Use shielded communication cables for serial ports to minimize EMI interference in industrial environments.
• Handle the module using proper ESD (Electrostatic Discharge) precautions to protect sensitive internal components.
• The lithium battery provides approximately six months of memory retention; ensure the battery is replaced periodically according to the maintenance schedule.
