Product Introduction
When environmental noise or mechanical bounce causes false input signals, the GE IC694MDL660 input module provides reliable detection with its selectable input filter times.
The GE IC694MDL660 is a high-density discrete input module from the PACSystem RX3i family, originally by GE Intelligent Platforms and now manufactured under Emerson Automation. It features thirty-two (32) input channels arranged in four (4) groups of eight (8), supporting both positive and negative logic. Each channel accepts an input voltage range of 0-30 VDC with a nominal input of 24 VDC and draws 7.0 mA per point at rated voltage.
Technical Specifications Breakdown
Key technical parameters of the GE IC694MDL660 include:
| Parameter |
Value |
| Number of Inputs |
32 (4 groups of 8) |
| Input Voltage Range |
0-30 VDC |
| Nominal Input Voltage |
24 VDC |
| Input Current per Point (at rated voltage) |
7.0 mA |
| Selectable Input Filter Times |
0.5 ms, 1.0 ms, 2.0 ms, 5 ms, 10 ms, 50 ms, 100 ms |
| Isolation (Field to Backplane) |
250 VAC continuous; 1500 VAC for one minute |
| Isolation (Group to Group) |

The selectable filter times allow the GE IC694MDL660 to ignore false positive and false negative signals caused by dust or mechanical debounce, enhancing reliability in harsh environments.
Installation & Setup Guidance
Install the GE IC694MDL660 in any RX3i rack. It requires a high-density terminal block: either box-style (catalog number IC694TBB032) or spring-style (catalog number IC694TBS032). Wire each input according to your logic type (positive or negative). The module is compatible with RX3i CPUs running release 2.90 or later. Do not use with Series 90-30 CPUs.
Each input channel has a dedicated LED indicator to show logic state: illuminated when active (logic 1), off when inactive.
Maintenance & Reliability
The GE IC694MDL660 incorporates diagnostic tools, including a terminal block that reports directly to the CPU, allowing quick identification of faults. The configurable input filters reduce maintenance needs by preventing false triggers. Regularly inspect wiring and terminal block connections for signs of wear or looseness to ensure long-term reliability.
Compatibility & Integration
The GE IC694MDL660 is part of the PACSystem RX3i family and integrates seamlessly with RX3i CPUs version 2.90 or higher. It works with the IC694TBB032 (box-style) or IC694TBS032 (spring-style) terminal blocks. The module has 48 input bits and 16 output bits for resolution.
Selection Guide & Purchasing Advice
Before purchasing the GE IC694MDL660, verify that your CPU is RX3i with firmware 2.90 or greater. Choose the appropriate terminal block based on your wiring preference. For reliable supply and expert support, contact UBEST Automation – your trusted partner for industrial automation parts.
