Description

The AJB-M1X Load Cell Indicator Controller is a device designed to interface with load cells for precise weight measurement, display, and process control in industrial weighing applications. While exact specifications depend on the manufacturer (e.g., AJB may refer to a brand like Aijia or similar), here’s a general overview based on typical features of such models:

Key Features:

1. Signal Processing:

   • Load Cell Input: Compatible with strain gauge load cells (e.g., 2mV/V or 3mV/V excitation).

   • High Resolution: 24-bit A/D converter for accurate weight measurement.

   • Multi-Range Calibration: Adjustable for various load cell capacities (e.g., 0–50t, depending on calibration).

2. Display & Interface:

   • LED/LCD Display: Clear digital readout (likely 6–8 digits) with units (kg, lb, t, etc.).

   • Backlit Screen: Adjustable brightness for visibility in low-light environments.

   • Keypad: Functions for tare, zeroing, calibration, and parameter configuration.

3. Control Functions:

   • Relay Outputs: For alarms, setpoint control (e.g., filling, batching), or triggering external devices.

   • Analog Output: 4–20mA or 0–10V signal for integration with PLCs, SCADA, or DCS systems.

   • Digital I/O: Optional inputs/outputs for start/stop signals or status feedback.

4. Communication:

   • RS-485/Modbus RTU: Common protocol for industrial communication (denoted by “M” in the model).

   • Optional: RS-232, Ethernet, or wireless modules (varies by manufacturer).

5. Power Supply:

   • Input: Typically 85–265V AC or 12–24V DC, depending on variant.

6. Environmental Protection:

   • IP Rating: Likely IP65/IP66 for dust/water resistance in harsh industrial environments.

Model Breakdown:

• AJB: Likely the manufacturer or series designation.

• M: Indicates support for Modbus communication.

• 1X: May denote a specific variant, capacity range, or feature set (e.g., single-channel input).

Typical Specifications:

• Accuracy: ±0.01–0.05% of full scale (FS).

• Sampling Rate: 50–200Hz for dynamic weighing.

• Operating Temperature: -10°C to 50°C.

• Mounting: Panel-mounted or DIN rail installation.

• Housing: Durable metal or ABS plastic.

Applications:

• Industrial Weighing Systems: Hoppers, tanks, silos, conveyor belts.

• Batch Control: Automated filling, dosing, or mixing processes.

• Checkweighing: Quality assurance in production lines.

• Process Automation: Integration with PLCs (e.g., Mitsubishi FX3U) or HMIs for closed-loop control.

Advantages:

• Compact & Robust: Suitable for space-constrained or harsh environments.

• Versatile Integration: Analog/relay outputs and Modbus support enable seamless PLC/SCADA connectivity.

• User-Friendly: Intuitive interface for quick setup and calibration.

Limitations:

• Calibration Complexity: Requires technical expertise for initial configuration.

• Limited Advanced Analytics: May lack cloud connectivity or advanced diagnostics without add-ons.

Notes:

• Confirm compatibility with your load cell’s specifications (excitation voltage, mV/V output).

• Verify communication protocols (e.g., Modbus addressing) for integration with existing systems.

• Always consult the manufacturer’s manual for wiring diagrams, calibration procedures, and safety guidelines.
