GE Fanuc Automation IC693APU300 High Speed Counter Module

GE Fanuc Emerson IC693APU300 high-speed counter module is designed for GE Fanuc Series 90-30 PLC racks to process high-frequency pulse inputs for precise counting in encoder signals, flow measurements, and motion feedback applications. It provides 12 positive-logic input channels and 4 positive-logic outputs, supports 5 VDC or 10–30 VDC input supply and 4.75–6 VDC or 10–30 VDC output, with up to 500 mA per output, and a maximum count rate of 200 kHz (minimum ~20 Hz / 20 kHz, mode dependent). Counter modes include Up, Down, Bi-directional, and Differential; power consumption is 250 mA at 5 VDC, and it mounts in a Series 90-30 baseplate with LED indicators for Board OK and Config OK. Common replacements include GE Fanuc IC693APU301, IC694APU300, and Allen-Bradley 1756-HSC.
