Here is the parameter introduction of the MOXA EDS-308-SS-SC-T unmanaged Ethernet switch:
10/100Base - T(X) Ports: It has 8 RJ45 - interface 10/100Base - T(X) ports, which support auto - negotiation of speed, full/half - duplex mode, and auto - MDI/MDI - X connection. This allows for easy connection to various Ethernet - enabled devices with different speed and duplex requirements.
The switch complies with IEEE 802.3 for 10Base - T, IEEE 802.3u for 100Base - T(X), and IEEE 802.3x for flow control. This ensures compatibility with a wide range of Ethernet - based networks and devices, enabling reliable data transmission and efficient network operation.
MAC Table Size: It has a MAC table size of 2 kbits, which allows the switch to store and manage the MAC addresses of connected devices for efficient data forwarding.
Packet Buffer Size: The packet buffer size is 768 k, which helps in handling bursty data traffic and ensures smooth data transfer even during high - traffic periods.
Processing Type: It adopts the store - and - forward processing type. In this mode, the switch receives the entire data packet, checks its integrity, and then forwards it to the appropriate port, ensuring accurate data transmission.
Fiber Cable Type: Usually supports standard single - mode or multi - mode optical fibers. For example, if it's multi - mode, it might be OM1 50/125 µm or OM2 62.5/125 µm. The specific type should be confirmed according to the actual product model and configuration.
Typical Transmission Distance: The transmission distance varies depending on the fiber type and optical power. For multi - mode fiber, it could be several hundred meters to a few kilometers. For single - mode fiber, it can reach tens of kilometers.
Wavelength: The TX (transmit) wavelength range is typically 1260 - 1360 nm for multi - mode or 1310/1550 nm for single - mode, and the RX (receive) wavelength range is 1100 - 1600 nm.
Optical Power: The TX power range is usually - 10 to - 20 dBm, and the RX sensitivity range is - 3 to - 32 dBm. The link budget and dispersion penalty are important parameters to consider for ensuring the quality of the optical link. The link budget is the difference between the transmitter power and the receiver sensitivity, which should be sufficient to cover the losses in the optical fiber and connectors. The dispersion penalty affects the signal quality over long - distance transmissions.
Input Current: It has an input current of 0.15 A @ 24 VDC. This indicates the amount of current the switch draws from the power supply at a specific voltage.
Operating Voltage: The operating voltage range is 9.6 - 60 VDC. It supports redundant dual - input power, which means it can accept power from two different sources, usually 12/24/48 VDC. This provides backup power in case one source fails, enhancing the reliability of the switch. It also has reverse - polarity protection and overload - current protection to prevent damage to the switch from incorrect power connections or excessive current. The power connector is a removable 6 - contact terminal block, which allows for easy installation and connection of the power supply.
Housing: The housing is made of metal, which provides good durability and protection against physical damage. It has an IP30 protection rating, which means it is protected against solid objects larger than 2.5 mm and is suitable for use in environments with some level of dust and debris.
Dimensions: The dimensions of the switch are 53.6 x 135 x 105 mm (2.11 x 5.31 x 4.13 in), making it a relatively compact device that can be easily installed in various locations, such as in a rack or on a wall.
Weight: It weighs 790 g (1.75 lb), which is lightweight enough for easy handling and installation.
Installation: The switch can be installed on a DIN - rail, which is a common mounting method in industrial control panels, or on a wall using an optional kit. This provides flexibility in installing the switch according to the specific requirements of the installation site.
Operating Temperature: The operating temperature range is - 10 - 60 °C (14 - 140 °F). This wide temperature range allows the switch to operate in various environmental conditions, from relatively cold to warm environments. However, it's important to ensure that the installation location is within this temperature range to ensure proper operation and reliability of the switch.
Storage Temperature: The storage temperature range is - 40 - 85 °C (- 40 - 185 °F). This range is wider than the operating temperature range and allows the switch to be stored in more extreme conditions for a short period before installation.
Ambient Relative Humidity: The ambient relative humidity range is 5% - 95% (non - condensing). This means that the switch can operate in environments with a wide range of humidity levels, as long as there is no condensation, which could cause damage to the internal components of the switch.
Safety: It complies with safety standards such as UL 508, UL 60950 - 1, CSA C22.2 No. 60950 - 1, and EN 62368 (LVD). These certifications ensure that the switch meets the safety requirements for use in industrial and commercial applications, protecting users and equipment from electrical hazards.
EMC: It meets the EMC (Electromagnetic Compatibility) standards EN 55032/35. For EMI (Electromagnetic Interference), it complies with CISPR 32 and FCC Part 15B Class A, which limits the amount of electromagnetic radiation emitted by the switch to prevent interference with other electronic devices. For EMS (Electromagnetic Susceptibility), it meets the requirements of IEC 61000 - 4 - 2 ESD (contact: 6 kV, air: 8 kV), IEC 61000 - 4 - 3 RS (80 MHz - 1 GHz: 20 V/m), IEC 61000 - 4 - 4 EFT (power: 2 kV, signal: 1 kV), IEC 61000 - 4 - 5 Surge (power: 2 kV, signal: 2 kV), and IEC 61000 - 4 - 6 CS (10 V), which ensures that the switch is immune to various electromagnetic disturbances in the environment.
Hazardous Locations: It may be certified for use in hazardous locations, such as ATEX Class I Division 2. This means that the switch is designed and tested to be safe for use in environments where there is a potential risk of explosion due to the presence of flammable gases, vapors, or dust.
Maritime: It may have DNV (Det Norske Veritas) certification, which is recognized in the maritime industry. This indicates that the switch meets the specific requirements for use in marine environments, such as resistance to salt - water corrosion, vibration, and shock.
MTBF: The Mean Time Between Failures (MTBF) is 2,382,553 hrs according to the MIL - HDBK - 217F standard. This indicates the expected reliability of the switch and provides an estimate of the average time between failures under normal operating conditions.
The MOXA EDS-308-SS-SC-T usually comes with a 5 - year warranty. This warranty covers any manufacturing defects or malfunctions that occur during the warranty period, providing customers with peace of mind and assurance of the product's quality.
