Industrial Applications

1. Remote Monitoring and Control of Industrial Sensors

Connecting legacy RS-232 based sensors or instruments in a factory automation setting, such as flow meters, pressure sensors, or temperature probes, to a central Ethernet-based control system. The NPort 5110-T enables data acquisition from these devices over the network.

Problem Solved

Legacy serial devices often lack direct Ethernet connectivity, making them difficult to integrate into modern IP-based control networks. The wide operating temperature range (-40 to 75°C) and robust metal housing ensure reliable operation in harsh industrial environments (e.g., non-climate-controlled factories, outdoor cabinets, heavy machinery areas) where standard office-grade equipment would fail. The 12-48 VDC input also suits industrial power supplies.

2. Network Integration for Outdoor Payment Terminals and Vending Machines

Providing network connectivity for RS-232 controlled payment terminals, barcode scanners, or telemetry modules in outdoor vending machines, kiosks, or smart lockers.

Problem Solved

Outdoor applications require devices that can withstand extreme temperatures (e.g., hot summers, cold winters). The -40 to 75°C operating temperature of the NPort 5110-T is perfect for these unattended, exposed locations. Its compact size allows for discreet installation within machine enclosures. The 12-48 VDC input is flexible for various power systems in these machines.

3. Integrating HVAC and Security Devices in Unconditioned Equipment Closets

Connecting RS-232-based HVAC controllers, access control systems, fire alarm panels, or power meters located in unconditioned building equipment rooms or utility closets to the building's main Ethernet network for centralized monitoring and management.

Problem Solved

Equipment rooms can experience significant temperature fluctuations. The -40 to 75°C operating temperature ensures the device server functions reliably without requiring additional climate control, reducing installation costs and energy consumption. The compact form factor and DIN-rail/wall mounting options are suitable for dense equipment racks or tight spaces.
