MOXA EDS-308-M-SC-T 8 Copper ports unmanaged Ethernet switches

Here is the parameter introduction of the MOXA EDS-308-M-SC-T unmanaged Ethernet switch:

Port Configuration

It has 7 10/100Base - T(X) RJ45 ports, supporting auto - negotiation of speed, full/half - duplex mode, and auto - MDI/MDI - X functionality.

There is 1 100Base - FX port with an SC connector, which is suitable for single - mode fiber. The fiber - optic port has the following characteristics: the fiber - optic cable type is 9/125 µm single - mode fiber, the typical transmission distance can reach 20 km (depending on the specific fiber - optic cable and environmental conditions), the TX wavelength is 1310 nm, the RX wavelength is 1550 nm, the TX power range is - 8 to - 15 dBm, and the RX sensitivity range is - 3 to - 32 dBm.

Network Standards

The switch complies with IEEE 802.3 for 10Base - T, IEEE 802.3u for 100Base - T(X) and 100Base - FX, and IEEE 802.3x for flow control.

Switching Capabilities

It has a MAC address table size of 2 kbits, used to store and manage the MAC addresses of connected devices.

The packet buffer size is 768 k, which can effectively handle bursty data traffic.

It adopts the store - and - forward switching mode.

Power Supply

Input Current: The input current is 0.12 A @ 24 VDC.

Voltage Range: It supports an operating voltage range of 9.6 - 60 VDC. It features redundant dual - input power (12/24/48 VDC) and is equipped with reverse - polarity protection and overload - current protection. The power connector is a removable 6 - contact terminal block.

Physical Characteristics

Housing: The housing is made of metal with an IP30 protection rating, providing good protection against dust and solid objects.

Dimensions: The dimensions are 53.6 x 135 x 105 mm (2.11 x 5.31 x 4.13 in), which is compact and suitable for various installation scenarios.

Weight: It weighs 790 g (1.75 lb), which is relatively lightweight for easy installation and handling.

Installation: It can be installed on a DIN - rail or on a wall using an optional mounting kit, offering flexible installation options.

Environmental Specifications

Operating Temperature: The operating temperature range is - 40 - 75 °C (- 40 - 167 °F).

Storage Temperature: The storage temperature range is - 40 - 85 °C (- 40 - 185 °F).

Relative Humidity: The ambient relative humidity range is 5% - 95% (non - condensing).

Standards and Certifications

Safety: It complies with safety standards such as UL 508, UL 60950 - 1, CSA C22.2 No. 60950 - 1, and EN 62368 (LVD).

EMC: For EMI, it complies with CISPR 32 and FCC Part 15B Class A. For EMS, 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).

Hazardous Locations: It is certified for use in hazardous locations, such as ATEX Class I Division 2.

MTBF: The Mean Time Between Failures (MTBF) is 2,646,710 hrs according to the MIL - HDBK - 217F standard, indicating its high reliability.

Other Features

It is equipped with a built - in relay warning function. When power failures or port failures occur, it can send out alarm signals to network administrators through relay output.

Warranty

Usually, the MOXA EDS-308-M-SC-T comes with a 5 - year warranty, providing customers with long - term quality assurance.
