GE Fanuc IC694APU300

Part Number: IC694APU300

The IC694APU300 is a high-speed counter module in the GE Fanuc RX3i PACSystems series, designed to efficiently handle rapid signal processing at frequencies of up to 1 MHz. This output module features a robust architecture that allows for immediate input detection and processing without the need for CPU communication, making it particularly suitable for applications like velocity measurement, process control, turbine flow meters, and meter proving. It supports configuration for one complex counter, two identical independent complex counters, or four identical simple counters.

Key specifications include 16 words of input memory, which consists of 16 bits of discrete input and 15 words of analog input memory, along with 16 bits of discrete output memory capable of transferring data once per CPU sweep. The module operates in two modes: Classic mode, which provides 16 bits of diagnostic information, and Enhanced mode, offering 32 bits of data to the CPU regarding module operation status.

The IC694APU300 comprises 4 positive logic outputs and 12 positive logic inputs with an operational voltage range of 5 V DC or 10-30 V DC, and draws power from the backplane’s 5 V DC bus while supporting user-supplied power for connected devices at +24 V DC. Installation best practices recommend using an enclosure that minimizes pollutants and employing shielded cables with high-frequency grounding to ensure signal integrity. The module incorporates internal diagnostics and a removable terminal block for easier field wiring, which should be conducted with copper wires of equal gauge. With no DIP switches for configuration, LED indicators are utilized to convey the operating status and diagnostic information. The IC694APU300 is an essential component for high-performance control systems that demand fast and reliable signal processing.
