L60AD4 MITSUBISHI MELSEC L Series 4-Channel Analog Input Module

The L60AD4 MITSUBISHI (Model: L60AD4) is a high-precision 4-channel analog input module engineered for Mitsubishi Electric MELSEC L Series Programmable Logic Controllers (PLCs). Designed for industrial process automation, the L60AD4 MITSUBISHI converts field analog voltage and current signals (0 to 10V DC, -10 to +10V DC, 0 to 20mA DC, and 4 to 20mA DC) into high-resolution 16-bit digital values for real-time control, data logging, and SCADA monitoring.

Outfitted with an 18-point removable terminal block, the L60AD4 MITSUBISHI features high-speed conversion (up to 20 microseconds per channel), channel-to-channel isolation, wire-break detection for 4-20mA loops, and configurable digital filtering. It provides exceptional measurement accuracy for processing feedback from pressure transducers, flow meters, temperature transmitters, and marine telemetry sensors.

Key Features of the L60AD4 MITSUBISHI

• 4 Universal Analog Channels: Supports voltage (-10V to +10V, 0V to 10V, 1V to 5V) and current (0 to 20mA, 4 to 20mA) inputs configured independently per channel.

• High-Precision 16-Bit Resolution: Delivers fine digital resolution up to 1/20,000 for accurate process signal digitization.

• Ultra-Fast Conversion Speed: High-speed analog-to-digital sampling rate of 20 microseconds per channel for rapid control loop response.

• Integrated Disconnection Detection: Automatically alerts CPU logic when wire breaks or open current loops occur on 1-5V or 4-20mA ranges.

• Removable 18-Point Terminal Block: Facilitates fast module replacement during routine cabinet maintenance without disconnecting field wiring.

• Advanced Onboard Filtering: Supports time-based, count-based, and moving average filtering directly on the module to smooth noisy process signals.

Primary Applications

• Process Control & Automation: Processing feedback from flow meters, pressure transmitters, level sensors, and position encoders

• Marine SCADA & Telemetry: Monitoring engine parameter signals, fuel oil viscosities, tank levels, and hydraulic pressures

• Factory Floor Machinery: Providing high-resolution analog measurement for hydraulic actuators, tension control systems, and HVAC skids
