Frequently Asked Questions
What is the maximum distance the Moxa IMC-21A-S-SC 100M can transmit data?
The Moxa IMC-21A-S-SC 100M is engineered for long-haul industrial networking. It supports data transmission distances of up to 100 kilometers. This extended reach is achieved by utilizing single-mode fiber optic cabling, which is far superior to copper for long-distance communication.
This significant range makes it ideal for connecting geographically dispersed sites. Applications include linking remote substations, field devices, or control centers across vast areas. The 100km capability is a key differentiator for demanding industrial environments.
The use of single-mode fiber is crucial for achieving these distances. It allows the optical signal to travel further with less dispersion compared to multi-mode fiber. The SC connector ensures a secure and reliable optical connection.
What type of fiber optic cable does the Moxa IMC-21A-S-SC 100M use, and what connector type?
This industrial media converter exclusively uses single-mode fiber optic cable. Single-mode fiber is designed for long-distance transmissions due to its smaller core diameter. This minimizes signal degradation and modal dispersion.
The specific connector type employed by the Moxa IMC-21A-S-SC 100M is the SC connector. SC connectors are a common and robust fiber optic connector type widely used in industrial and telecommunications applications. They provide a secure push-pull latching mechanism.
When connecting this device, ensure you use a single-mode SC-to-SC fiber optic patch cable. Using multi-mode fiber or the wrong connector type will result in communication failure or significantly reduced performance.
How is the Moxa IMC-21A-S-SC 100M powered, and what are its power input requirements?
The Moxa IMC-21A-S-SC 100M features a wide-range DC power input capability. This allows it to accept voltages from 9.6 VDC up to 60 VDC. This flexibility is crucial for industrial environments where various power sources are common.
This wide input range ensures compatibility with a broad spectrum of industrial power supplies, including 12 VDC, 24 VDC, and 48 VDC systems. The device typically connects via screw terminals for a secure power connection.
Ensuring a stable and correctly rated DC power source is essential for reliable operation and longevity. Over-voltage or incorrect polarity can damage the unit, so always verify power supply specifications before connecting.
