GE Fanuc IC694MDR390 Mixed I/O Module RX3i

IC694MDR390 GE RX3i Mixed Input Output Module

Product Introduction

The IC694MDR390 is a versatile mixed I/O module designed for the GE Fanuc RX3i PacSystem PLC series. This module combines 8 individually-isolated inputs and 8 normally-open relay outputs in a single unit. The inputs support both sinking and sourcing configurations, accommodating positive or negative logic systems. Meanwhile, the outputs are arranged into two groups of four points each, providing flexible load control. This module requires an external user-supplied AC or DC power supply for operation. Its mixed design saves rack space and simplifies system architecture.

Input Specifications and Features

The IC694MDR390 offers 8 individually-isolated inputs with a single common terminal. Each input accepts a wide voltage range of 5 to 30 Volts DC. The nominal input rating sits at 24 Volts DC, drawing 7.5 milliamps typically. These inputs can sink or source current, giving you compatibility with various field devices. For instance, you can connect limit switches, electronic switches, pushbuttons, and other standard industrial sensors. The isolation rating between inputs reaches 500 Volts AC (RMS), protecting the PLC backplane from electrical noise and surges. The maximum input response time is 7.5 milliseconds for both on and off transitions, ensuring timely signal detection.

Output Specifications and Capabilities

The relay outputs on the IC694MDR390 consist of 8 normally-open (NO) contacts, divided into two groups of four outputs each. Each output circuit handles a switching capacity of 2.0 Amperes continuously, with a maximum inrush rating of 5.0 Amperes. The outputs support a broad voltage range: 5 to 250 Volts AC (at 50 to 60 Hz) or 5 to 30 Volts DC. This versatility allows you to drive solenoids, indicators, motor starters, and other field devices directly. Each output point provides 500 Volts AC (RMS) isolation, enhancing system safety and reliability. The minimum load requirement is 10.0 milliamps, while the maximum on/off response time reaches 15 milliseconds.

Power Requirements and Backplane Draw

The IC694MDR390 draws a modest 6 milliamps from the 5.0 Volts DC backplane supply. This low current demand ensures compatibility with standard RX3i power supplies. However, note that the module requires an external user-supplied power source for its field circuits. This external supply must match the voltage and current requirements of your connected input and output devices. Proper external power sizing ensures reliable operation and prevents overloading the internal backplane.

LED Indicators and Status Monitoring

The front panel of the IC694MDR390 features 16 individual LEDs. Each LED corresponds to one I/O point, showing its current on or off status. These indicators provide immediate visual feedback, simplifying troubleshooting and system monitoring. For instance, you can quickly verify whether an input is receiving a signal or an output is energized. This feature saves time during commissioning and maintenance activities.

Installation Guidelines

You can install the IC694MDR390 in any available slot within the RX3i PacSystem I/O backplane. However, this module does not support hot insertion or hot removal. Therefore, always power down the system before installing or removing the module. Following this precaution prevents potential damage to the module or backplane. After installation, connect your field devices to the terminal blocks according to the wiring diagrams provided in the user manual. Ensure proper grounding and shielding for optimal performance.

Group Configuration and Isolation

The module organizes its outputs into 2 groups of 4 points each. This grouping allows you to power different output groups from separate external supplies if needed. Each group shares a common terminal, providing flexibility in system design. Meanwhile, the inputs form a single group with a common terminal. The point-to-point isolation ensures that faults on one channel do not affect others, improving overall system robustness.

Environmental Specifications

• Operating temperature: 0°C to 60°C

• Storage temperature: –40°C to 85°C

• Relative humidity: 5% to 95% (non-condensing)

Typical Applications

The IC694MDR390 suits a wide range of industrial control applications. For example, it works well in packaging machinery, conveyor systems, and material handling equipment. Additionally, it fits process control applications requiring mixed digital I/O. Its ability to handle both AC and DC loads makes it particularly useful in retrofit projects where legacy devices have varying power requirements. By combining inputs and outputs in one module, you save rack space and reduce overall system cost.
