Industrial 4-Port RS485 to Ethernet Module
A highly compact DIN-rail gateway providing 4 independent RS485 channels. Engineered to connect multiple legacy field instruments to your local area network while saving critical cabinet space.
Extreme Environment Durability & 15KV ESD Protection
Built for the harshest industrial control panels. The flame-retardant alloy plastic shell withstands up to 110°C without melting. Combined with ±15KV air discharge protection and a certified -40°C to 85°C operating range, it guarantees zero downtime in extreme electrical environments.
Bi-Directional Transparent Transmission & Multi-Mode
Provides a reliable, zero-data-loss tunnel between your serial devices and LAN. Fully supports TCP Server, TCP Client, and UDP modes to adapt to diverse network topologies.
Modbus RTU to TCP Protocol Conversion
Acts as an autonomous protocol bridge. Allows modern Modbus TCP SCADA networks to effortlessly query and control legacy Modbus RTU meters and PLCs.
MQTT & JSON Edge Computing for IoT
Accelerate your cloud integration. The gateway automatically parses raw serial telemetry into structured JSON payloads and pushes them directly to MQTT brokers for real-time dashboarding.
