General Electric IC694MDL660 Input Module

The GE IC694MDL660 provides high-density signal acquisition for the PACSystems RX3i automation platform. This discrete input module features 32 points to monitor various industrial field devices. It efficiently processes signals from sensors, limit switches, and pushbuttons within a compact hardware footprint. By utilizing four isolated groups, the module ensures superior noise immunity and channel protection.

Hardware Specifications and Environmental Data

Configurable Filtering and Response Logic

The IC694MDL660 includes advanced input filtering to eliminate signal interference. Users can select from seven different filter times ranging from 0.5ms to 100ms. These settings effectively prevent false triggers caused by mechanical contact bounce. Consequently, the module delivers highly accurate data to the RX3i CPU. Accurate filtering ensures stable performance in electrically noisy environments.

System Integration and Diagnostics

Real-time status monitoring occurs through individual LED indicators on the front faceplate. These LEDs provide instant visibility for troubleshooting and field commissioning. For physical connectivity, the module requires high-density terminal blocks such as the IC694TBB032. Furthermore, the IC694MDL660 requires RX3i CPU firmware version 2.90 or higher for full functionality. Note that this module does not support legacy Series 90-30 backplanes.
