Precision counting applications demand fast and accurate pulse accumulation. The GE IC693APU300 delivers reliable high speed counting for industrial automation. This module functions as an optional HSC card for the Series 90-30 platform. GE Fanuc originally produced this unit, and Emerson Automation now supports it.

Construction and Interface Layout
This module features a rugged plastic housing with internal shielding. Such a design protects counting circuits from electrical noise interference. Furthermore, the GE IC693APU300 provides a front-accessible terminal block for field wiring. You will find 16 screw terminals on this interface. Each terminal accepts wire sizes from 0.2 to 1.5 mm². An LED array shows the active status for every input and output channel.
Energy Storage and Signal Processing
Unlike standard discrete modules, this high speed counter includes dedicated accumulator registers. The board uses small filter capacitors to debounce incoming pulse signals. Consequently, the GE IC693APU300 counts cleanly even with noisy field wiring. Each of the 12 inputs features a programmable threshold for voltage detection. This flexibility allows mixing of 5V and 24V sensors on the same module. The unit does not require battery backup for counter value retention.
Installation and Mounting Requirements
Installing the GE IC693APU300 takes only a few minutes of work. The unit slides directly into a Series 90-30 PLC rack slot. It also locks securely with a top-mounted retaining clip. Always disconnect all field power before inserting or removing this module. The unit uses passive cooling without any internal fans. This design eliminates dust accumulation and moving parts. The module occupies a single slot in the main rack.
Integration with PLC Systems
This high speed counter works perfectly with GE Series 90-30 CPUs. It reads pulses from encoders on conveyors, cutters, and packaging machines. Operators can configure the four outputs for preset value triggering. The GE IC693APU300 also supports quadrature encoder inputs for position tracking. Consequently, this module remains an excellent choice for high speed counting tasks. The unit delivers consistent performance across a 0°C to 60°C temperature range.
