The General Electric IC693APU300 is a dedicated High-Speed Counter (HSC) module engineered for the Series 90-30 PLC platform. This module provides advanced pulse-counting capabilities, allowing for high-frequency signal processing that operates independently of the main PLC CPU scan cycle. This architecture ensures precise data acquisition even in high-speed applications, preventing the loss of pulses that can occur during standard scan delays.

Features

• Twelve (12) positive logic inputs supporting 5 VDC or 10-30 VDC signal ranges.
• Four (4) positive logic outputs with flexible voltage ratings (10-30 VDC at 500 mA or 4.75-6 VDC at 20 mA).
• Maximum pulse count rate of 200 kHz.
• Selectable input filtering (2.5 microseconds or 12.5 milliseconds) to mitigate high-frequency noise and contact bounce.
• Windowing functionality to validate strobe inputs within specific counter ranges.
• Independent processing capability for real-time motion and process control.

Applications

The IC693APU300 is suitable for industrial environments requiring precise pulse-based monitoring and control, including:

• Flow metering and totalizing for turbine flowmeters.
• Velocity and speed measurement for rotating equipment.
• Material handling and conveyor synchronization.
• Motion control applications such as injection molding and cut-to-length machinery.
• Registration control in printing and winding equipment.

Technical Specifications

Installation Guidelines

• Ensure the PLC baseplate power is disconnected before inserting or removing the module.
• The module occupies a single I/O slot on the Series 90-30 baseplate.
• Use shielded cabling for high-frequency input signals to minimize EMI interference.
• Properly ground the module and associated field wiring to the system common to prevent ground loops.
• Verify that input voltage levels (5V or 10-30V) match the specific field device requirements before wiring.

FAQ

What is the primary role of the IC693APU300?

It acts as a high-speed counter interface, offloading pulse-counting tasks from the CPU to ensure accurate measurement of high-frequency signals up to 200 kHz.

Can this module handle mixed signal voltages?

Yes, the module is designed to accept either 5 VDC or 10-30 VDC inputs, providing flexibility for various sensor types.

Does the module require external power?

The module draws 5 VDC from the backplane for internal operations, while the output channels require a user-supplied 10-30 VDC or 4.75-6 VDC power source.
