NB-IoT RS-485 Wireless Gateway
WW-5C20 - Transform Your Wired Industrial Systems to Wireless IoT
Industrial IoT Made Simple
The Wintec WTC1N / WTC1C is a compact NB-IoT gateway that bridges the gap between traditional RS-485 industrial equipment and modern cloud-based monitoring systems. Transform your existing Modbus devices into wireless IoT endpoints without replacing infrastructure.
Ideal for: Generator monitoring via Modbus meters, cathodic protection rectifier telemetry, water/gas meter reading, industrial sensor networks, and remote PLC connectivity.
Key Features
Compact, ruggedized gateway for connecting industrial RS-485 devices to cellular IoT networks
🔌 RS-485 Modbus RTU
Native Modbus RTU support with configurable baud rates (1200-230400 bps). Connect directly to PLCs, energy meters, flow sensors, and industrial controllers without protocol conversion.
📡 NB-IoT Connectivity
Reliable cellular connectivity on Australian networks (Telstra, Optus) using NB-IoT technology. Lower cost than 4G with excellent building penetration for basement and underground installations.
📊 Analog & Digital I/O
One analog/digital input (0-10V, 0-20mA, 4-20mA) and one digital output for direct sensor connection and control. Perfect for adding simple sensors alongside Modbus devices.
💧 IP68 Waterproof
Fully sealed outdoor-rated enclosure withstands harsh environments. Deploy in pump stations, outdoor enclosures, or underground vaults with confidence.
⚡ Industrial Power Range
12-36V DC input with 5V/200mA output for powering external sensors. Wide voltage tolerance handles noisy industrial power supplies and vehicle batteries.
