Y511-L LoRaWAN Edge Gateway with Modbus Integration

Key Features

8 receive / 1 transmit or 16 receive / 2 transmit channels, with Ethernet, Wi-Fi and optional 4G backhaul

Forward packets to an external Network Server or order local Network Server / Application Server software

JavaScript payload decoding, message transformation, scheduled acquisition and local rules with local-service software

MQTT, HTTP, TCP and WebSocket application integration in the local-service configuration; supported message directions vary by protocol

Modbus TCP/RTU server exposes mapped end-device registers to PLCs on compatible software; RS485 hardware is standard

9–28 VDC supply and up to 15 W maximum power for the higher-power 16-channel full-duplex configuration

Specifications

LoRaWAN Radio

Supported End Device Versions: LoRaWAN 1.0.2 / 1.0.3 / 1.0.4
Supported End Device Classes: Class A / Class C
Frequency Plans: CN470 (default), EU433, EU868, AU915, IN865, AS923, RU864, US915; region-specific hardware; specify the AS923 sub-plan when ordering
Channel Options: 8 RX / 1 TX or 16 RX / 2 TX
Duplex: Half-duplex or full-duplex hardware options
Transmit Power: Up to 27 dBm; use settings allowed by the regional plan
Receiver Sensitivity: Down to -140 dBm at SF12, BW125 kHz
Spreading Factor: SF7–SF12
Capacity: Device capacity depends on payload size, reporting interval, airtime, interference and regional radio limits. Channel count alone does not determine capacity.

Network Interfaces

Ethernet: 10/100 Mbps RJ45
Wi-Fi: 2.4 GHz, AP+STA, IEEE 802.11 b/g/n
Cellular: Optional 4G; supported operator bands depend on the cellular module
RS485: Standard A/B hardware; Modbus RTU integration requires compatible software
USB: MicroUSB USB-TTL debug/log interface

Edge Software

Local NS/AS: Local Network Server / Application Server (NS/AS), available as a software option
JavaScript: Payload encoding/decoding, message conversion, downlink commands, scheduled acquisition and local rules with local NS/AS
MQTT: Application uplinks and downlinks in local-service configuration
HTTP: Push supported uplink, acknowledgement, and gateway-status messages only; downlinks require a separate supported protocol
TCP: Gateway acts as an application TCP client; requires application framing, payload schema adaptation, and reconnect configuration
WebSocket: Bidirectional application session in local-service configuration
Remote Forwarding: In external Network Server mode, configure application integration on the external server

Modbus Integration

Role: Modbus TCP/RTU server/slave exposing mapped end-device holding registers to a PLC or supervisory client/master, on compatible software
Mapping: Requires scripts, payload decoding, Unit IDs, register layout, scaling, and byte-order configuration
Freshness: Mapped measurement registers can contain values from an earlier uplink. Check data age and the reporting interval. A successful write response does not prove that a wireless output changed state.

Power Supply

Voltage: DC 9–28 V; typical DC 12 V
Maximum Current: 1.25 A at DC 12 V
Average Power: ≤5 W
Maximum Power: Up to 15 W for the higher-power 16-channel full-duplex configuration

Environmental

Operating Temperature: -20 to 70 °C
Storage Temperature: -40 to 85 °C
Humidity: 0–95% RH, non-condensing
Location: Indoor

Mechanical

Dimensions 8 Channel: 120.4 × 79.7 × 34 mm
Dimensions 16 Channel: 125.5 × 120.4 × 34 mm
Weight 8 Channel: Approximately 1 kg
Weight 16 Channel: Approximately 1.5 kg
Mounting: DIN rail or wall mounting with the matching bracket

Deployment

Regional Matching: Match gateway, Network Server, and end-device plans and channel groups, including AS923 sub-plan
Downlinks: Class A receives downlinks after an uplink. Class C provides more receive opportunities. Delivery time depends on airtime, server scheduling and regional radio limits.
Ordering: Specify radio hardware, 4G option, local NS/AS services and Modbus integration with your order
