Loss-in-Weight Weighing System for Flow Control & Dosing Automation

Contact for Pricing

The Laumas TAIPAN265 is a precision-engineered loss-in-weight regulator designed for real-time material dosing, batching, and flow control in demanding industrial environments. Housed in a compact DIN-mount enclosure, the TAIPAN265 delivers advanced weight monitoring and proportional output regulation, ideal for automated feeders, extruders, and dosing machines. It supports RS232/RS485 serial communication with Modbus RTU, ASCII, Profibus DP, and Ethernet (optional) for full system integration. Featuring a high-contrast two-line LCD display, 6 relay outputs, 8 PNP inputs, and analogue control output, TAIPAN265 ensures accurate material flow with automatic correction, plus real-time alarm response when deviation occurs.

Key Features

• Display: 2-line LCD, 16 characters per line (6 mm height), backlit
• Inputs: 8 optoisolated PNP digital inputs, 1 load cell input, encoder input
• Outputs: 6 relay outputs (max 115 VAC/0.5 A), 1 analogue output (0–10 V, 4–20 mA)
• Communication: RS232, RS485, Profibus DP (optional), Modbus RTU, ASCII, Ethernet (optional)
• Set Point Management: Control up to 15 dosing points (via RS232 or BCD)
