Connects the IOTB2-LZ/BZ modular smart MCBs and the IOTB2LM smart moulded-case circuit breakers.
Protocol forwarding
Supports the MQTT-JSON, TCP-MODBUS and RTU-MODBUS protocols, plus integration with API and SDK development kits.
Edge collaboration
Links on-site data collection, status reporting and platform management.
Project deployment
For engineered wired-connection projects that use RS485 and Ethernet between modular breakers and the platform.

Product details
GWY-RL Ethernet IoT Gateway
Applications
The Ethernet modular gateway serves indoor projects using IOTB2-LZ/BZ modular smart MCBs and IOTB2LM smart moulded-case circuit breakers. It provides RS485 downstream connection and Ethernet uplink communication. The display version is GWY-RL; the non-display version is GW-RL.
Gateway appearance and connections
The version with display is used for on-site status viewing and commissioning.
The non-display version is used for standard connection inside the cabinet.
