Product Details
Module Performance and Architecture
The IC694MDL660 is a high-density discrete input solution for the GE Fanuc PACSystems RX3i platform, featuring 32 independent points configured for either positive or negative logic (sinking or sourcing). To enhance system reliability and noise immunity, the module is architected into four isolated groups of eight inputs each. This allows for the integration of different power sources or logic types within a single slot, making the IC694MDL660 an ideal choice for space-constrained control cabinets requiring high I/O throughput.

Installation and Field Wiring
Due to its high density, the IC694MDL660 requires a high-density terminal block or a specialized Fujitsu-style connector interface (often used with Interposing Terminals or CAB-series cables). Unlike lower-density 16-point modules, this unit does not utilize the standard 20-screw terminal block directly on the faceplate. Proper grounding of the isolation groups is essential to maintain the 1500 VAC dielectric strength rating across the system.
Technical FAQ and Comparison
How does this differ from the IC694MDL645?The IC694MDL660 provides double the density with 32 points, whereas the MDL645 offers only 16 points. The MDL660 is more efficient for high-scale logic processing but requires more complex wiring management due to the increased pin count.
Can I mix Sinking and Sourcing logic on the same module?Yes. Because the IC694MDL660 features four isolated groups, you can wire one group for positive logic and another for negative logic, provided each group has its own dedicated common return.

Tech & Buying Guide
Why 24V DC Power Supplies Standardize Modern Industrial Automation
Industrial control cabinets worldwide rely on 24V DC as the universal power standard for field instrumentation, sensors, and controllers. Walk into any manufacturing plant, and you will find PLCs, human-machine interfaces (HMIs), and smart actuators running on extra-low voltage DC. Standardizing on 24V DC enhances operational safety, lowers cabinet footprint, and maintains steady control performance across factory networks.
Essential Motion Control Commands: A Practical Guide for Engineers
Automation engineers often rely on precise position and speed control to drive modern factory machinery. Modern industrial systems, such as Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS), depend heavily on standardized motion instructions. Mastering these commands ensures operational safety, protects mechanical components, and optimizes cycle times across production lines.
Mastering Modern Industrial Joystick Controls in Heavy Automation
Industrial joysticks play a pivotal role in human-machine interaction across heavy material handling and mobile hydraulics. These tactile controllers translate complex operator movements into precise electrical signals for PLCs, motion controllers, and DCS networks. Consequently, selecting and installing the right joystick architecture ensures operator safety, reduces fatigue, and optimizes equipment performance.
