Functional Features:

• Supports ladder logic, function block, and structured text programming
• Built-in real-time clock for time-stamped data logging
• Online program editing and monitoring capability
• Supports up to 8 PID control loops simultaneously
• Integrated data logging function with timestamp

Structural Features:

• Compact DIN-rail mountable plastic housing

• Terminal block connectors for all I/O and power connections
• Conformal coating on main PCB for environmental protection

Working Principle:
The CPU executes user-defined control programs stored in non-volatile memory. It cyclically scans input states, executes the control logic, and updates output states. The RS-232C serial port (S3 variant) enables point-to-point communication with HMI panels, programming terminals, or SCADA systems.

Advantages & Highlights:

• High processing speed of 0.5 ms/instruction for fast response control
• Compact form factor reduces panel space requirements
• Integrated I/O eliminates need for separate I/O racks in small applications
• Cost-effective solution for standalone machine control

Applicable Industries:

• Water and wastewater treatment
• Food and beverage processing
• Chemical batch processing
• Building automation (HVAC)
• Small-scale manufacturing

Installation Requirements:

• Mount on DIN rail (TS35) or screw-mount to control panel
• Maintain minimum 50 mm clearance above and below for ventilation
• Use shielded cable for communication lines exceeding 5 meters
• Ensure proper grounding of the CPU chassis to earth ground

Usage Precautions:

• Do not exceed 24 VDC ±10% on the power supply input
• Do not connect inductive loads directly to output terminals without snubber circuits
• Avoid exposure to corrosive gases, excessive dust, or direct sunlight
• Firmware updates must be performed using Yokogawa-approved tools only
