Moxa ICF-1150I-S-SC-T Wide Temp RS-232/422/485 Fiber Link

Product Overview

The Moxa ICF-1150I-S-SC-T (ICF1150ISSC T) serves as a critical infrastructure component for extending serial communications over vast distances using optical fiber. This 100% brand new, original industrial converter transforms RS-232, RS-422, or RS-485 signals into single-mode fiber optic signals, enabling a massive 40 km transmission radius. By utilizing fiber optics, the device provides total immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), which frequently disrupt traditional copper-based serial lines. Designed for mission-critical deployments in energy infrastructure, transportation systems, and factory automation, this unit maintains network stability where standard serial cables fail.

Technical Specifications

The ICF-1150I-S-SC-T integrates high-speed baudrate support with robust physical layer protection.

Engineering Advantages

The Moxa ICF-1150I-S-SC-T eliminates common field integration bottlenecks through several proprietary technologies:

• Zero-Configuration RS-485 Management: The patented ADDC® (Automatic Data Direction Control) hardware logic manages the data direction of RS-485 signals automatically. This removes the need for complex software coding or baudrate-dependent dip-switch settings, ensuring immediate "plug-and-play" functionality for half-duplex systems.

• Galvanic Isolation for Ground Loop Mitigation: The integrated 2 kV isolation barrier separates the serial signals from each other and from the power supply. This prevents ground loop currents from damaging expensive PLC ports or SCADA servers, particularly in outdoor or heavy industrial environments.

• Deterministic Communication for Non-Standard Rates: This converter supports non-standard baudrates via internal hardware detection. This capability allows engineers to integrate legacy or proprietary industrial devices that do not follow standard 9600 or 115200 bps increments without losing data packets.

• Extreme Environmental Resilience: The "T" variant ensures full operation in unconditioned cabinets subject to –40°C or +85°C temperatures. The rugged IP30 housing protects the internal circuitry from the vibrations and thermal cycling found in energy substations and roadside traffic control boxes.

FAQs

• What is the benefit of using single-mode fiber over multi-mode for this device?

  Single-mode fiber used by the ICF-1150I-S-SC-T supports much longer distances (up to 40 km) compared to multi-mode (typically 2–5 km) due to lower signal attenuation and higher bandwidth-distance product, making it ideal for remote field sites.

• How does the ADDC® feature help with RS-485 installation?

  In traditional RS-485 systems, you must carefully time the data direction switching. ADDC® handles this at the hardware level, sensing when data arrives and switching the driver automatically, which prevents data collisions and simplifies the commissioning of half-duplex networks.

• Does the unit require a specific fiber optic connector?

  Yes, this specific model utilizes SC connectors. Ensure your single-mode fiber patch cables match the SC interface to secure a low-loss optical connection.

• Can I use the RS-232 and RS-485 ports simultaneously?

  The device supports the conversion of one serial standard at a time to fiber. However, it provides both terminal block and DB9 interfaces to allow flexible wiring for the specific standard (RS-232, RS-422, or RS-485) required by your application.
