Product Overview
The GE IC694MDL660-EC is a high-performance 32-point 24V DC digital input module designed for GE’s RX3i PACSystems platform, a cornerstone of industrial automation solutions. Engineered to deliver reliable signal acquisition in demanding environments, this module supports both positive and negative logic inputs, operating seamlessly within a voltage range of 0–30V DC. Its four isolated groups of eight inputs each (totaling 32 channels) provide robust protection against electrical interference, making it ideal for applications where signal integrity is critical, such as automotive assembly lines, chemical processing plants, and pharmaceutical manufacturing facilities.
As part of the RX3i ecosystem, the GE IC694MDL660-EC integrates seamlessly with GE’s RX3i CPUs (version 3.50 or later) and supports flexible configuration through software-based input filtering (adjustable from 0.5ms to 100ms). Its compact form factor (3.4 cm x 14.5 cm x 14 cm) and rugged construction allow installation in any I/O slot of the RX3i chassis, providing scalability for systems ranging from small-scale machinery to large industrial complexes. Key features include green LED indicators for real-time input status monitoring and a terminal block (TB) lock detection system, which uses a red LED to alert users of loose connections.

Installation and Maintenance
Pre-installation Preparations: Before installing the GE IC694MDL660-EC, ensure the RX3i chassis is powered off and disconnected from the mains. Verify compatibility with the RX3i CPU (version 3.50 or later) and inspect the module for physical damage, such as bent pins or cracked housing. Clean the chassis connectors and terminal block slots to ensure a secure fit. Use compatible terminal blocks (e.g., GE IC694TBB032) for reliable wiring.
Maintenance Suggestions: Regularly check the module’s LED indicators for 异常 status (e.g., constant red TB LED) and inspect terminals for loose connections. Dust accumulation on the module’s surface should be removed using a dry, lint-free cloth to maintain optimal cooling. During system shutdowns, visually inspect the isolation barriers for signs of wear. If replacement is needed, power down the system and follow GE’s guidelines for safe module removal and installation.
