WR200 Industrial 4G LTE Router, RS232/RS485 Port

The WR200 is an industrial-grade 4G LTE router designed for unmanned and harsh-environment deployments where reliable cellular connectivity must coexist with legacy industrial serial protocols. With built-in RS232/RS485 interfaces, ESIM + external SIM dual support, DC 9–48V wide voltage input, 48V PoE, and hardware watchdog, it delivers a complete cellular gateway solution for PLC integration, IoT sensor networks, self-service terminals, and remote site monitoring.

Ideal For

• Industrial IoT — connecting PLCs, SCADA systems, and Modbus sensors over 4G LTE
• Unmanned remote sites — oil wells, pump rooms, power substations, and water treatment plants
• Self-service terminals — vending machines, kiosks, advertising displays, and ticketing systems
• Fleet management and vehicle tracking requiring RS232/RS485 serial connectivity
• Distributed retail and banking networks needing centralized cloud management
• ISPs and system integrators delivering industrial cellular gateway solutions

Industrial Design and Power Flexibility

The WR200 is built for environments where consumer and office-grade routers fail. The metal enclosure dissipates heat in enclosed cabinet installations, and the DC 9–48V wide voltage input handles the unstable power rails common in industrial sites — from 12V vehicle power to 48V telecom DC systems — without requiring external voltage regulators or converters.

The 48V PoE input on the WAN port adds further flexibility: the WR200 can be powered directly from an existing PoE switch in the distribution cabinet, eliminating the need for a separate power supply or terminal block wiring in rack and panel installations.

For mounting, two options are provided: standard 35mm DIN rail clip for installation in IEC 60715 electrical cabinets, and four-screw panel mount for wall-mounted enclosures or custom industrial housings. The compact 146×96×36mm footprint fits the space constraints of typical electrical control panels.

RS232/RS485 Serial Integration

The RS232 and RS485 interfaces on the WR200’s terminal block connect directly to industrial serial devices — PLCs, Modbus RTU sensors, industrial meters, and SCADA equipment — that lack native Ethernet or cellular interfaces.

The router acts as a transparent serial-to-cellular gateway: serial data from connected devices is encapsulated and transmitted over the 4G LTE uplink to cloud servers or enterprise SCADA platforms. This removes the need for separate serial converters or industrial M2M modules at each device, reducing component count and wiring complexity in the control cabinet.

ESIM and Remote SIM Management

The built-in ESIM chip combined with the external SIM slot provides operational flexibility for large-scale deployments. A software switch selects between ESIM and physical SIM without physical card access — critical for devices installed inside sealed enclosures, elevated structures, or restricted-access industrial facilities.

For fleet deployments across multiple mobile operators or regions, ESIM profile switching enables carrier failover and regional SIM provisioning without dispatching field technicians to each site — the primary operational cost advantage of ESIM in industrial IoT at scale.

VPN and Secure Remote Access

The WR200 supports PPTP and L2TP VPN client modes, establishing encrypted tunnels over public 4G networks to connect remote industrial sites to corporate LAN infrastructure. Field engineers can access PLC programming interfaces, check sensor readings, or update SCADA configurations from headquarters without exposing industrial network ports to the public internet.

Combined with the cloud management platform, VPN remote access eliminates unplanned site visits for routine maintenance — reducing the operational cost that makes distributed industrial infrastructure expensive to support.

Cloud Fleet Management

Integration with the Alibaba IoT platform enables batch management of WR200 fleets at scale. Configuration profiles can be pushed to large numbers of devices simultaneously, online/offline status is monitored in real time, and OTA firmware upgrades are scheduled during maintenance windows — all without on-site presence.

The platform supports secondary development via open APIs, allowing system integrators to embed WR200 management into their own monitoring dashboards or SCADA platforms and deliver customers a unified interface across all industrial IoT devices.
