FAQ

1. What is the main function of the 1783-ETAP2F?
The 1783-ETAP2F is an EtherNet/IP Tap designed to provide a connection point between an industrial EtherNet/IP network and fiber-optic network segments. It has one copper RJ45 port and two fiber ports, allowing copper Ethernet equipment to be integrated with a dual-fiber network architecture. It is particularly useful in industrial environments where fiber communication is required for longer distances or improved immunity to electromagnetic interference.

2. How many copper and fiber ports does the 1783-ETAP2F have?
The 1783-ETAP2F provides one copper RJ45 Ethernet port and two fiber-optic ports. The copper port can be connected to compatible EtherNet/IP equipment using suitable industrial Ethernet cabling, while the two fiber ports provide optical network connections. This 1-copper-plus-2-fiber configuration makes the device suitable for integrating local copper-based equipment with a fiber-based industrial network.

3. What type of fiber does the 1783-ETAP2F support?
The 1783-ETAP2F uses 100Base-FX fiber communication and supports multimode glass fiber with 50/125 μm or 62.5/125 μm specifications. The optical wavelength is 1310 nm, and the fiber interfaces use LC connectors. During installation, the fiber type, connector specification, optical power budget, and transmission distance should be checked to ensure compatibility with the connected network equipment.

4. What is the maximum fiber communication distance of the 1783-ETAP2F?
The maximum specified fiber channel length is 2 km. Actual communication distance depends on the complete optical link, including fiber attenuation, connector insertion loss, cable quality, and the number of connection points. For a reliable industrial network installation, engineers should evaluate the complete optical power budget instead of considering only the nominal fiber cable length.

5. What power supply does the 1783-ETAP2F require?
The 1783-ETAP2F requires a 24 V DC power supply, with an allowable input range of 20.4–27.6 V DC. The power input is designed for Class 2/SELV applications. Maximum current consumption is approximately 260 mA at 24 V DC, resulting in a maximum power consumption of 6.24 W. The DC power supply should provide stable voltage and sufficient capacity for continuous operation, while power wiring should be installed according to the requirements of the industrial control system.

6. What type of Ethernet cable should be used with the 1783-ETAP2F?
The copper Ethernet connection should use at least Category 5e cable suitable for industrial Ethernet applications. Correct cable selection helps maintain stable communication between the tap and connected Ethernet equipment. In industrial installations, Ethernet cables should be routed separately from high-voltage and high-current wiring where practical. Shielding, grounding, connector quality, cable routing, and the surrounding electromagnetic environment should also be considered when designing the network.

7. What is the operating temperature range of the 1783-ETAP2F?
The operating temperature range is -25°C to +60°C. This allows the device to be used in a wide variety of industrial environments. However, the actual temperature around the tap can be affected by the control cabinet, nearby power equipment, ventilation, and other heat-producing components. For long-term reliable operation, the device should be installed where adequate airflow is available and should not be positioned directly beside components that generate excessive heat.

8. Can the 1783-ETAP2F be used for long-distance industrial network connections?
Yes. The 1783-ETAP2F is suitable for industrial network applications where fiber communication is needed over distances up to the specified 2 km fiber channel length. Its two 100Base-FX fiber interfaces allow fiber links to be incorporated into an EtherNet/IP network, while the RJ45 port provides local copper Ethernet connectivity. Fiber communication is also useful in environments with significant electromagnetic interference because optical fiber is not affected by electrical noise in the same manner as copper cabling. When designing the connection, the fiber type, optical budget, connector losses, transmission distance, and compatibility of all network components should be verified.
