Why RS485 Modbus RTU Matters

Remote Monitoring & Control
Connect your dosing pump directly to a PLC or SCADA system for centralized management. Adjust flow rates, monitor performance, and trigger alarms—all without touching the pump.

Real-Time Data Exchange
RS485 enables fast, bidirectional communication. Receive live feedback on stroke rate, dosing volume, and system status to optimize chemical usage and reduce downtime.

Multi-Device Networking
RS485 supports multi-drop architecture, allowing multiple pumps to communicate over a single twisted-pair cable. Ideal for complex dosing setups with multiple injection points.

Noise-Resistant & Long-Distance
RS485 is engineered for industrial environments. It resists electrical noise and supports cable runs up to 1,200 meters—perfect for large plants or remote installations.

Flexible Configuration
The TPG Modbus Series offers configurable communication parameters:

• • Baud rate: 19200
  • Data bits: 8
  • Stop bit: 1
  • Parity: Even
  • Max PDU size: 253 bytes
  •  
  • Reliable Data Integrity
    Each device manages its own RS485 transceiver, ensuring clean data exchange without collisions or errors—critical for dosing accuracy and system safety.

Ideal for:

• Water treatment plants with centralized control rooms
• Chemical dosing in automated manufacturing lines
• Agricultural fertigation systems with remote telemetry
• Any facility using PLCs, HMIs, or SCADA platforms
