PRODUCT INFORMATION
Product Overview
The General Electric IC697ALG440 is an analog input expander module for Series 90-70 programmable logic controllers. It features 16 current input channels supporting a range of 4 to 20 milliamps. This expander functions with a base converter module to form an analog input subsystem. Systems can combine expander modules with the base converter for up to 120 input channels. The unit converts signals and presents converted data in two's complement format.
An internal analog multiplexer connects inputs sequentially to the analog-to-digital converter circuit. Diagnostic facilities provide status indicator LEDs, expander channel response detection, and module health monitoring. The module draws 0.4 Amps at 5 Volts DC from the backplane. It provides 16-bit resolution with an analog update rate of 2.4 milliseconds. This module must reside in the same rack adjacent to related subsystem modules.
