3BSE018161R1 IC694MDL350 GE Isolated 16-Point AC Module

Product Overview

The GE Fanuc IC694MDL350 operates as a high-density discrete output module for the PACSystems RX3i PLC platform. It provides 16 independent, isolated output channels designed to drive AC field devices such as motor starters, solenoid valves, and indicator lights. Operating at a nominal voltage of 120/240 VAC, this module ensures superior signal separation, preventing electrical noise and ground loops from affecting the backplane logic. We supply this component as 100% Brand New original hardware, specifically optimized for high-speed serial bus communication on both universal and standard RX3i baseplates.

Engineering Advantages

The IC694MDL350 addresses critical performance and maintenance needs in process automation:

• Channel-to-Channel Isolation: The 16 isolated outputs allow the module to control field devices powered by different AC phases or different power sources. This isolation prevents a single electrical fault from propagating across multiple channels, significantly increasing overall system uptime.

• Smart CPU Diagnostics: The module continuously monitors the status of the field-side terminal block. It reports any wiring discrepancies or terminal connection issues directly to the RX3i CPU, enabling operators to identify and resolve faults via the software interface without manual probing.

• High-Current Surge Handling: An inrush capacity of 20 Amps for a full cycle allows the module to handle the high startup currents required by inductive loads like large contactors and solenoids. This robustness prevents nuisance tripping and premature component wear.

• High-Speed Serial Bus Performance: The module utilizes the RX3i high-speed serial bus. This ensures that the CPU updates all 16 output states within a single scan cycle, providing the rapid response times necessary for synchronized packaging and material handling applications.

FAQs

Q: Which terminal blocks are compatible with the IC694MDL350?A: This module requires a dedicated terminal block for field wiring. You must use either the IC694TBBX32 (Box style) or the IC693TBSX32 (Spring style) connectors. Please note that the terminal block is sold separately from the module.

Q: Does the IC694MDL350 support hot-swapping?A: Yes. The PACSystems RX3i architecture supports hot insertion and removal of the IC694MDL350. This allows you to replace a module during maintenance without powering down the entire PLC rack, minimizing process interruptions.

Q: Are there internal fuses to protect the 16 output channels?A: No, the IC694MDL350 does not contain internal fusing. Engineers should provide external fusing for each output point or group to protect the module and field wiring from overcurrent conditions or short circuits.

Q: What is the minimum firmware requirement for the RX3i CPU?A: To ensure full diagnostic reporting and high-speed bus compatibility, your RX3i controller must run firmware version 3.5 or higher. Using earlier firmware may result in communication errors or limited diagnostic visibility.
