Description

The GE Fanuc IC609TCU100 is a dedicated hardware Timer/Counter Setpoint module engineered for the legacy Series One Junior and Series One Plus central processing units (CPUs). This module provides real-time adjustments and tracking of preset values for process control timers and counters. Utilized across manufacturing assembly lines, textile processing, and chemical batch operations, it enables precise timing loops and batch counting adjustments directly from the physical control panel. By bypassing complex software terminal modifications, this device allows maintenance personnel to safely alter critical machine parameters on the fly, reducing operational downtime and preventing timing discrepancies during active PLC program execution.

Features

• Four independent circuits mapped to 4-digit BCD (Binary Coded Decimal) thumbwheel switches.
• Localized diagnostics via integrated RUN (green) and CPU (red) status LEDs.
• Direct interface port for high-speed connection to the Series One controller core.
• Enables manual parameter adjustment without requiring software terminal access.
• Compact, industrial-grade faceplate design for panel mounting.

Applications

This unit is designed for use in legacy GE Fanuc Series One Junior and Series One Plus PLC systems. It is commonly deployed in applications requiring frequent adjustment of timing or counting setpoints, such as batch processing, assembly line sequencing, and industrial machine control.

Technical Specifications

Installation Guidelines

• Ensure the PLC system is powered down before installing or removing the module from the rack.
• Verify that the interface port is correctly aligned with the controller backplane to prevent pin damage.
• Thumbwheel adjustments should be performed under stable operating conditions to ensure the CPU reads accurate register variables.
• Maintain proper ventilation within the control cabinet to ensure the ambient temperature remains within the 0 to 60 deg C range.
• Follow standard ESD (Electrostatic Discharge) handling procedures when touching internal circuitry or connectors.

FAQ

Can this module be used with other GE Fanuc PLC series?

No, the IC609TCU100 is specifically engineered for the Series One Junior and Series One Plus product lines and is not compatible with other GE Fanuc PLC families.

Do I need to stop the PLC to change the thumbwheel settings?

While the unit allows for on-the-fly adjustments, it is recommended to ensure the system is in a stable state to avoid potential data corruption or unexpected process behavior during register updates.
