The IMC-101G from Moxa is an industrial media converter that enables a reliable Gigabit connection between copper and fiber optic networks in demanding environments. The device serves as a bridge between Ethernet networks via copper cables (RJ45) and fiber optic cables (SFP module), enabling flexible and powerful network integration in industrial applications. The conversion takes place in the Gigabit range, with the interface supporting 10/100/1000BaseT(X), allowing adaptation to various network operating modes. The integrated 1000BaseSFP slot allows the use of SFP transceivers for multimode, singlemode, or long-distance transmission, enabling flexible design of range and network topology.

Applications

The IMC-101G is designed for use in industrial environments, particularly in automation systems, utility networks, and marine applications. The certification for hazardous areas (Class 1 Div. 2 / ATEX Zone 2 / IECEx) makes the device suitable for installations in hazardous zones where high safety and reliability are required. The robust metal construction and extended temperature range down to -40 °C for the -T models ensure stable operation under extreme environmental conditions.

Functions and Equipment in Detail

The device features a relay output that triggers an alarm signal in case of power failure or port interruption. The Link Fault Pass-Through (LFPT) function ensures that a network fault at the copper port is directly passed to the fiber optic port, enhancing network operational safety. Power supply is provided via a redundant DC input in the range of 12 to 48 VDC, with integrated overcurrent protection. Connections are made via a terminal block, ensuring a secure and durable connection.

Technology Explained Simply

The IMC-101G uses media converter technology to transmit data between different transmission media (copper and fiber optic) without changing the network operating mode. The RJ45 interface supports Auto-MDI/MDI-X and Auto-Negotiation, enabling automatic adaptation to the connected device configuration. The SFP slot is compatible with modules from the SFP-1G series, suitable for various fiber optic standards (SX, LX, LHX, ZX). The protection rating IP30 protects the device against solid foreign objects larger than 2.5 mm and against splashing water, but not against direct water jets or immersion. The operating temperature ranges from 0 to 60 °C for standard models, and from -40 to 75 °C for -T models.

Compatibility and Accessories

The IMC-101G is compatible with SFP transceivers from the SFP-1G series, which can be used for multimode, singlemode, and long-distance transmission. Using these modules extends the range and flexibility of the converter. The devices are designed for mounting on DIN rails, enabling easy integration into existing enclosures. Certifications include EMC and EMS standards (EN 55032/35, FCC Part 15B, CISPR 32, IEC 61000-4-2 to -4-11), safety standards (UL/EN 60950-1), as well as vibration tests (IEC 60068-2-6). Explosion protection certifications (UL Class 1 Div. 2, ATEX Zone 2, IECEx) apply to the IEX models.

Mounting and Installation

Mounting is done via a DIN rail, enabling quick and secure installation in enclosures. Power supply is via a terminal block, ensuring a secure and durable connection. Connections are clearly labeled, and the devices are designed for use in industrial environments, with the robust metal construction providing good resistance to mechanical stress.

Operational Advantages

The IMC-101G offers high operational reliability through redundant power supply, relay output for alarms, and LFPT function. Support for SFP modules enables flexible network orientation, and certifications for hazardous areas extend the range of applications. The long MTBF of 500,540 hours (Telcordia, GB) and the 5-year manufacturer's warranty underline the reliability of the device. Mounting on DIN rail and compact design (53.6 x 135 x 105 mm) facilitate integration into existing systems.

Scope of Delivery

The scope of delivery includes the IMC-101G media converter, a quick start guide, and a warranty card. The devices are designed for use in industrial networks and meet the requirements for reliability, safety, and flexibility in demanding environments.
