Technical Features & Benefits
The GE IC693APU300-MA is a high-speed counter (APU – Auxiliary Processing Unit) module designed for Series 90-30 PLC systems. What makes it stand out is its onboard intelligence: it processes pulse signals independently, allowing the PLC to focus on higher-level control logic.
Each module provides two independent input channels capable of counting up to 80 kHz, handling quadrature encoder inputs, single-ended pulse trains, or up/down direction counting. Engineers can configure each channel individually for applications like rate measurement, frequency detection, or linear position tracking.
Because this unit belongs to the Series 90-30 modular family, installation and system integration are straightforward. It communicates across the PLC backplane, exchanging data with the CPU through the I/O bus. Configuration is handled via GE’s programming software, where engineers can assign scaling factors, presets, and counting modes.
From a performance standpoint, the IC693APU300-MA features hardware debouncing and noise suppression — critical in electrically noisy environments. It’s also built with an industrial-grade circuit design that withstands vibration, temperature fluctuations, and electrical transients. LEDs on the module faceplate indicate status for power, channel activity, and error diagnostics, simplifying field troubleshooting.
Key operational benefits include:
- Reduced CPU load: Onboard counting and interrupt handling mean faster overall system response.
- High precision: Ideal for motion and process applications requiring sub-millisecond feedback.
- Flexible configuration: Supports multiple counting and timing modes, easily adapted for different machinery types.
- Rugged reliability: Proven GE design ensures long-term operation in tough industrial settings.
Engineers appreciate that the GE IC693APU300-MA combines speed, accuracy, and simplicity — characteristics that define the most reliable automation hardware.
