MYPIN LH86-IRRD: 6-Digit LED Weighing Controller with High-Precision Display for Batch Control

The MYPIN LH86-IRRD is a compact, rugged weighing controller designed for precise batching, weighing, and process control in small to mid-sized production environments. With a robust 6-digit LED display, this device gives you crystal-clear readouts at a glance, ensuring accuracy even in fast-paced lines. Built around the versatile LH series platform, it combines a high-resolution 24-bit A/D converter with multi-channel load cell support to deliver reliable, repeatable results every time.

Why this weighing controller stands out

• Six-digit LED accuracy—a bright, easy-to-read readout that makes quick adjustments and monitoring effortless in busy environments.
• Supports 1–4 load cells—ideal for multi-point weighing and distributed batch systems without needing additional hubs.
• High-precision 24-bit A/D—delivers clean, stable signals even when the environment has minor electrical noise.
• Multiple outputs for seamless automation—relay/SSR control for actuators, and 4–20 mA output for analogue control loops; also supports 0–10 V and 0–5 V signals for flexible integration.
• Comprehensive communications—RS-485, RS-232, and LAN RJ45 with MODBUS-RTU protocol to connect PLCs, SCADA, or industrial networks.
• Batch and tare control—START/STOP and clear tare functionality simplify repetitive batching and make calibration quick and repeatable.
• Peak data hold (optional)—capture and recall peak weights for quality checks or traceability audits.
• Universal power—90–260 VAC or DC input with a 5V auxiliary supply for accessories, simplifying installations in diverse facilities.
• Compact, durable design—ABS enclosure, 96 × 48 × 80 mm footprint, ready to slot into control panels or instrument racks.

Designed for integration into automated lines, the LH86-IRRD gives you reliable, real-time weight data with flexible control signals. Use it to manage precise ingredient dosing, portioning, or packaging weights, then feed results directly into your PLC or SCADA system to maintain consistent product quality.

Ideal use cases

• Batching and portioning in food, chemical, or pharmaceutical production where precise weight targets must be met consistently.
• Automated weighing stations that require multiple load cells for distributed weighing or tank monitoring.
• Packaging lines needing reliable relay/SSR actuation and analogue feedback for closed-loop control.
• Systems that rely on MODBUS RTU over RS-485 or serial interfaces for easy integration with existing PLCs.

Practical guidance for getting the most from your LH86-IRRD

• Plan your network topology around RS-485 for multi-device communication; leverage MODBUS RTU to centralize data collection.
• Utilize the 4–20 mA output or the 0–10 V/0–5 V signals to drive process controllers, tightening control loops for tighter batch tolerances.
• Combine Start/Stop controls with the TARE function to simplify repetitive batching tasks and reduce setup time between lots.
• Take advantage of the optional Data/Peak hold to document peak weights for batch traceability and quality audits.
• Keep the device powered from 90–260 VAC/DC for flexible installation; use the internal 5V auxiliary supply to power peripherals as needed.

Whether you’re building a compact packaging line, refining a small-scale production process, or integrating precise measurement into a control system, the MYPIN LH86-IRRD stands out as a capable, adaptable weighing controller. Its combination of high-precision measurement, rich output options, and easy network integration makes it a practical upgrade for operators looking to improve consistency, efficiency, and data visibility across their weighing operations.
