Installation & Configuration Guide

Preparation (10 min)

• Verify the incoming power supply is 24V DC with a tolerance of ±10%.
• Ensure the rack is clean and free of debris to prevent short circuits.
• Gather necessary tools: Phillips screwdriver, anti-static wrist strap, and a multimeter.

Removal (5–10 min)

• Power down the entire PLC rack and disconnect all external cables.
• Remove retaining screws from the module faceplate.
• Carefully slide the module out of the backplane to avoid damaging the connector pins.

Installation (10 min)

• Insert the IC660TBA026M into an available slot in the chassis.
• Ensure the module is fully seated against the backplane connector.
• Tighten the retaining screws to secure the unit in place.

Power-On & Test (10 min)

• Reconnect all cables and restore power to the rack.
• Observe the front-panel LEDs; the “RUN” light should illuminate solid green.
• Use a programming terminal to verify the firmware version matches the expected release.
• Perform a cyclic redundancy check (CRC) on the memory to ensure data integrity.

‍♀️ FAQ

• Q: Is this module compatible with the GE 90-70 series?
  A: No, the IC660TBA026M is strictly for the 90-30 series. The 90-70 uses a different form factor and firmware.
• Q: What is the maximum memory expansion for this CPU?
  A: The base unit supports 128K Byte RAM, but it can be expanded up to 512K Bytes with additional memory modules.
• Q: I received a module labeled “New Original.” What does that mean?
  A: “New Original” indicates the unit is new in original factory packaging, never installed, and sourced directly from GE surplus or authorized distributors.
• Q: Do I need to reprogram my system after installing this module?
  A: No, the logic and data are stored in the memory module (IC660BBA001), not the CPU itself. Simply swap the CPU and the system should resume operation.
• Q: Can I use this in a hazardous location?
  A: Yes, the GE 90-30 series (including the TBA026M) is UL Listed for Class 1, Division 2 hazardous locations, suitable for Zone 2 environments.
