Simplify your setup. Connect devices wirelessly. Transmit data securely.
ü Long-distance wireless communication via ISM bandg\
ü Battery-powered portable version for mobile setups
ü Available as stationary or portable version
ü Supports Modbus RTU protocol
ü AES 128-bit encryption for secure data transmission
ü Scalable solution for multi-point monitoring
ü Quick configuration with S4C-WTU mobile app
ü Repeater mode for extended wireless range
The WTU (Wireless Transmission Unit) replaces
traditional wiring with a robust wireless link between Modbus master and slave
devices. It is the ideal solution for transmitting data across compressed air
networks where cabling is impractical or costly.
Available in Three Models
Designed for flexible use, the WTU is available
in three models:
ü WTU-S for
stationary installations
ü WTU-P with
integrated battery for portable use
ü WTU-PM for mobile master devices like the S551
With plug and play connectivity, standard connectors and encrypted transmission, the WTU ensures secure and reliable communication between sensors, data loggers and gateways—even over long distances or across buildings.
The WTU can act as a Master, Slave or Repeater, allowing users to tailor the wireless setup to any site condition or infrastructure layout.
Advanced Wireless Integration
SUTO’s S4C-WTU app makes device setup intuitive and mobile-friendly. View system status, configure wireless and Modbus settings, or run signal strength tests—all directly from your phone. The guided setup reduces installation time and simplifies scaling as the monitoring system grows.
With multi-sensor support per WTU slave,
and up to 16 devices per master, the WTU ensures complete coverage of your
measurement points.
