PRODUCT INFORMATION
Product Overview
The General Electric IC694APU300 is a PACSystems RX3i High-speed Counter Module for measurement applications. It operates on 250 mA or 1.25 watts sourced from the 5 V backplane bus. The module provides a maximum count rate of 1 MHz. Its operational duty cycle ranges from 25% to 87%. Input circuits support 12 positive logic single-ended lines or 6 differential lines. Off-state leakage current remains capped at 10 μA per point.
The IC694APU300 provides four positive logic outputs rated for up to 1.5 A resistive load. Output operating voltage spans 4.7 to 40 V DC. Overcurrent protection incorporates self-healing capability with an inrush threshold of 1.6 A. Reverse polarity protection prevents damage from reversed OUTPWR and OUTCOM wiring. Group-to-group isolation withstands 250 VAC continuous and 1500 VAC for one minute. The module supports CMOS load drive capability.
