The TLM500 series switches provide superior
industrial quality with high/low temperature and lightning protection through
fanless cooling circuit design, wide operating temperature range and high
protection level. They also integrate rich functions such as switching,
security and management. Support for the public Ethernet Ring Protection
Protocol (ERPS), greatly improving the flexibility and availability of
networking, and enhancing the reliability and security
of industrial networks.

Energy-saving design, green communication
- Follow IEEE 802.3az EEE (Energy Efficient Ethernet) to provide a
low-power idle mode for ports, which greatly reduces device power consumption.
- Fanless design, while reducing the power consumption of the device,
the silent design allows you to avoid the noise.
- Port sleep when the port is not connected, avoiding power waste and
further reducing device power consumption
Power redundancy protects the network stability
- Non-polar DC power supply，power supply over-voltage protection and over-current
- Supports dual power supply
redundancy (when a power supply is abnormal, the device can work stably and
without network disconnection), which greatly improves the high availability of
the device, thus providing a more stable and reliable network.
Industrial quality, adapt to extremely harsh environments
- The working environment temperature range is -40 ° C to 85 ° C, and
the relative humidity range of the working environment is 5% to 95% without
condensation. Can adapt to a variety of harsh application environments.
- Dustproof, lightning protection, surge protection, EFT, ESD, etc.
all achieve a high protection level.
- The line-speed Layer 2 switching capability is available on all
ports to ensure that all ports are forwarded without blocking.
