PRODUCT INFORMATION
Product Overview
The General Electric IC693MDL655 is a Series 90-30 Discrete I/O module. This high-density digital input module provides thirty-two input points for discrete signal processing. The module divides the thirty-two inputs into four isolated groups of eight channels each. It accommodates nominal 24 VDC positive or negative logic inputs from diverse industrial sensors.
The module installs directly into any available single slot of a Series 90-30 baseplate. It supports central processing unit baseplates, expansion racks, and remote input-output baseplates. Two front-mounted 24-pin connectors interface field wiring through dedicated pre-wired cable assemblies. Status indicators provide individual channel visual feedback across all four operating input groups.
