Moxa ToughNet Switch
Version 2.1, January 2021
*1802058000012*
Overview
The ToughNet TN-5816A/5818A switches are high performance M12
Layer 3 Ethernet switches that support Layer 3 routing functionality to
facilitate the deployment of applications across networks.
TN-5816A/5818A switches use M12 and other circular connectors to
ensure tight, robust connections and guarantee reliable operation against
environmental disturbances, such as vibration and shock.
TN-5816A/5818A switches support isolated power in the 24 to 110 VDC
power input range, allowing the same model to be used at different sites
around the globe. TN-5816A/5818A switches provide up to 16 Fast
Ethernet M12 ports with 2 bypass relay ports, and 2 Ethernet interface
Gigabit ports with bypass relay functionality. Furthermore, with a -40 to
75°C operating temperature and IP54-rated waterproof enclosure, the
switches can be deployed in harsh environments. The TN-5816A/5818A
series Ethernet switches are compliant with mandatory sections of EN
50155, covering operating temperature, power input voltage, surge, ESD,
and vibration, as we ll as conformal coating and power insulation, making
the switches suitable for a variety of industria l applications.
