GE Fanuc IC694MDL340D Discrete Output 24VDC 0.5A 32-Point

GE Fanuc IC694MDL340D PACSystems RX3i 32-Point Discrete Output Module

The IC694MDL340D (Model: IC694MDL340D) is a high-density discrete output module designed for the GE Fanuc (Emerson) PACSystems RX3i platform. This module provides 32 sourcing (positive logic) digital outputs, enabling the precise control of DC field devices such as solenoids, interposing relays, and status indicators. Operating within a 12/24 VDC range, the IC694MDL340D is engineered for mission-critical applications that demand high-speed switching and robust electrical isolation. Its compact design allows for maximum I/O density within the RX3i rack, making it a preferred choice for large-scale manufacturing and process automation environments.

High-Density Output Control and Safety

The IC694MDL340D utilizes a sourcing configuration, where the module provides the positive voltage to the load. This is a standard safety architecture in many industrial sectors, as it ensures that a short circuit to ground will not inadvertently energize the field device. To maintain signal integrity and protect the sensitive RX3i CPU, the IC694MDL340D (Model: IC694MDL340D) features optical isolation between the field-side wiring and the PLC backplane. This isolation prevents high-voltage spikes or electrical noise from interfering with the system's logic execution.

Detailed Technical Specifications

The following parameters detail the electrical and operational characteristics of the IC694MDL340D (Model: IC694MDL340D). Please note that while some legacy IC694MDL340 units were 120VAC 16-point modules, the IC694MDL340D revision is specifically a 32-point DC sourcing module.
