Technical Description

WTC-65 series RTU are expandable version of WTC-63 series, which can add more inputs and outputs signals according to the customer’s needs. The WTC-65 RTU features one RS485 and one RS232 acquisition interface, as well as 8 AI/DI and 4 DO interfaces. It can provide power supply for sensors through the VEXT output. It fully supports 4G as well as 3G and 2G cellular networks. The device enables scheduled data acquisition and transmission, and supports standard communication protocols such as hydrology, water resources management, environmental monitoring, and MQTT.

Features

●   Supports various types of meters and transmitters.

●   Plug-and-play design for flexible functional configuration.

●   Ultra-low power consumption, compatible with multiple power supply modes to reduce costs.

●   Compact size with DIN rail mounting, allowing easy integration into other devices.

●   Remote data transmission via 4G/5G/NB-IoT; supports multi-center and multi-port communication.

Function

●  Data Acquisition: Automatic collection of meter data/equipment status.
●  Wireless Communication: Supports 4G/5G/NB-IoT, SMS, Bluetooth, and other communication methods.
●  Intelligent Alarm: Automatic alerts for out-of-range data or field device failures.
●  Timed Power Supply: Scheduled power output to provide operational power for meters and transmitters.
●  Remote Maintenance: Remote modification of device parameters/reporting frequency; remote firmware upgrades.
●  Data Storage: Automatic storage of monitoring data with dual backup (local device & monitoring center).
●  Logic Control: Automatic/remote control of pumps, valves, gates, etc. (Only DATA-6501-01).

• How does the WTC-65 adapt to evolving project needs?

  • ​Field-expandable I/O architecture:​​ ✓ Start with ​8AI/DI + 4DO​ base ✓ Add sensors/actuators via ​RS485 + RS232​ ports ✓ Scalable ​VEXT power​ (12V/24V) for added devices → Customize without replacing hardware

• What enables plug-and-play deployment in remote monitoring?

  • ​Universal connectivity + autonomous operation:​​ • ​Multi-network support: 4G/3G/2G cellular (rural/urban) • ​Industry protocols: MQTT/Hydrology/Water Resources • ​Scheduled operations: Timed data collection/transmission • ​Sensor power: VEXT output eliminates extra PSUs
