PRODUCT INFORMATION
Product Overview
The General Electric IC694ALG222 is an Analog input voltage module for the PACSystems RX3i platform. This module accepts unipolar signals from 0 to 10 Volts. It also accepts bipolar signals from -10 to +10 Volts. Users can configure up to sixteen single-ended channels or eight differential channels. Single-ended wiring references signals to ground and maximizes available channel density. Differential wiring uses two signal leads to provide increased resistance to electrical interference.
The module features optical isolation rated at 250 Volts AC continuous to the backplane. Isolation withstands 1500 Volts AC for one minute. Channel update rates reach 6 milliseconds for single-ended mode and 3 milliseconds for differential mode. Diagnostic indicators include a Module OK LED and an internal power supply status LED. Field signals terminate at a removable twenty-terminal connector block included with the module.
