NS-205 5 Unmanaged 10/100Mbps Fast Ethernet Ports w/Auto Negotiation

Supported Applications

The Omega NS-205 Series is an unmanaged industrial Ethernet switch designed for rugged environments. It provides network connectivity in applications requiring reliable data transmission over standard Ethernet protocols, supporting up to five workstations or devices within a local area network.

Operating Conditions & Performance

The series operates across an ambient temperature range of -40 °C ~ +75 °C and supports storage temperatures from -40 °C ~ +85 °C. It functions in relative humidity levels between 10% to 90% non-condensing (or 10% ~ 90% RH, non-condensing). The device features a compact profile with overall dimensions of 33 mm x 78 mm x 107 mm (W x L x H) and utilizes a plastic casing rated UL 94V-0 for flammability.

Performance specifications include support for IEEE 802.3, IEEE 802.3u, and IEEE 802.3x standards with store-and-forward processing at wire speed switching. The switch provides a memory bandwidth of 1.4 Gbps and includes flow control via IEEE 802.3x and back pressure mechanisms.

Configuration Options

The NS-205 Series offers configurable power inputs, model variants for regulatory compliance, and specific accessory options to support installation requirements.

• Model Variants: The series includes the standard NS-205, the RoHS-compliant NS-205 CR, and the wide-input voltage model NS-205A CR.
• Power Supply Options: Available power supplies include the GPSU06-6 (24V/0.25A, 6 W), KWM020-1824F (24V/0.75A, 18 W), and DIN-KA52F (24V/1.04A, 25 W with DIN-Rail Mounting).
• Port Configuration: Five shielded RJ-45 ports support 10/100 Base-T(X) auto-negotiation and auto MDI/MDI-X functionality.

The device accepts power via a 3-Pin Removable Terminal Block. Input voltage ranges are +10 VDC ~ +30 VDC (non-isolation) for the NS-205 and NS-205 CR models, while the NS-205A CR model supports +12 VDC ~ +48 VDC.

Key Product Differences

Differences within the series are defined by input voltage ranges and regulatory compliance:

• NS-205: Standard unmanaged 5-port industrial Ethernet switch with +10 VDC ~ +30 VDC power input.
• NS-205 CR: Unmanaged 5-port industrial Ethernet switch compliant with RoHS, featuring the same +10 VDC ~ +30 VDC power input range.
• NS-205A CR: Unmanaged 5-port industrial Ethernet switch compliant with RoHS, distinguished by a wider power input range of +12 VDC ~ +48 VDC.

All models include LED indicators for Power and Link/Act status (Yellow/Green) to monitor network activity. The series incorporates protection features including 4KV ESD protection, Ethernet isolation rated at 1500 Vrms for 1 minute, power reverse polarity protection, and a Frame Ground pin for EMS protection.he device accepts power via a 3-Pin Removable Terminal Block.
