Description

The Samkoon S-E4AI2AO is an industrial automation device, likely part of Samkoon’s PLC or
I/O module lineup, designed for processing analog signals. Here’s a structured overview based
on typical features of such models:
Key Specifications:
• Analog Inputs (AI): 4 channels, likely supporting standard signals (e.g., 0–10V, 4–
20mA, thermocouples, or RTDs). Check the datasheet for exact compatibility.
• Analog Outputs (AO): 2 channels, possibly 0–10V or 4–20mA outputs for
controlling devices like valves, VFDs, or actuators.
• Resolution: Typically 12–16 bits for precise signal conversion.
• Communication: Likely supports RS-485/Modbus RTU for integration with HMIs,
SCADA systems, or other PLCs.
• Power Supply: Common ratings include 24V DC; verify voltage requirements in
the manual.

Applications:
• Industrial automation (e.g., process control, HVAC, water treatment).
• Monitoring sensors (temperature, pressure, flow).
• Controlling analog actuators or drives.
Installation & Compatibility:
• Wiring: Ensure proper shielding for analog signals to prevent noise interference.
• Software: Samkoon devices often use proprietary software (e.g., SAMS3 for
HMIs or PLC programming tools). Confirm compatibility with this model.
• Expandability: May integrate with other Samkoon modules via bus interfaces.
Troubleshooting Tips:
• Signal Noise: Use twisted-pair cables and ground shields appropriately.
• Configuration: Verify input/output ranges (e.g., voltage vs. current) in software
settings.
• Calibration: Check for calibration requirements if readings are inaccurate.
Recommendations:
• Consult the official Samkoon S-E4AI2AO datasheet for exact specifications.
• Contact Samkoon support or distributors for firmware, software tools, or
replacement units if discontinued.
• Consider newer models (e.g., Samkoon S-Series PLCs) if upgrades are needed.
