GE IC693APU300
4. Product Introduction
The GE IC693APU300 is a high-speed counter module designed for GE Series 90-30 PLC systems, enabling precise motion control and flow measurement. It processes up to 200 kHz input signals (80 kHz sustained) for applications like turbine flowmeters, encoder wheels, and material handling systems.
Core Advantages:
-
Multi-Mode Counting: Configurable for up/down, bidirectional, or differential counting (A/B quad encoders).
-
Input Filtering: Adjustable filtering (2.5 µs/12.5 ms) eliminates noise for reliable signal processing.
-
Compact Design: 12 inputs + 4 outputs in a single-slot module, reducing panel footprint by 60%.
-
Safety Features: 1500V isolation protects PLCs from electrical noise.
5. Firmware/Software Versions & Upgrade Notes
-
Recommended Firmware: v3.0.1 (last stable Series 90-30 release; fixes communication bugs).
-
Compatibility:
-
PLC Compatibility: Series 90-30 CPUs (e.g., IC693CPU331).
-
Configuration Tools: Logicmaster 20/30 or Proficy Machine Edition (IEC 61131-3 compliant).
-
-
Upgrade Risks:
-
v3.0.1 requires PLC cold restart (no hot-swap).
-
Downgrading to v2.9.x may disable enhanced filtering modes.

6. Frequently Asked Questions (FAQ)
1. Can I hot-swap the IC693APU300?
No. Hot-swapping risks backplane shorts. Power down the rack, verify 5V/24V stability, then replace. The module’s 250 mA backplane draw demands stable power—test with a multimeter first.
2. Is this module obsolete?
Yes. OEM discontinued it in 2022. Use IC693APU301 (identical form factor, enhanced ESD protection) or migrate to RX3i IC694APU300 (1 MHz input rate).
3. How do I configure counting modes?
Use Proficy Machine Edition to select A/B/C modes. For encoder inputs, configure dual A/B quad channels. Changes require a PLC restart.
4. What’s the warranty for “New Surplus” units?
12 months, covering manufacturing defects. We perform:
-
Incoming traceability checks (OEM serial verification).
-
24h load test (250 mA continuous output).
-
Megger insulation test (>10MΩ).
5. Why is this cheaper than OEM but pricier than refurbished?
This is New Surplus: unused stock with full QC (anti-static packaging, calibration backups). Refurbished units often have degraded capacitors or untested isolation—risking unplanned downtime.
6. How to verify input accuracy?
Use a signal generator to inject pulses (e.g., 100 kHz). Monitor
%AQregisters in Proficy. If discrepancies occur, check:-
Input filter settings (2.5 µs vs. 12.5 ms).
-
Field wiring (shielded STP cable, ground to “GND”).
7. Can I use this for high-speed motion control?
Yes. The 80 kHz sustained rate supports VFDs and servo drives. For 1 MHz inputs (e.g., optical encoders), use IC694APU300 (RX3i-compatible).
