• Relay contacts open or close to switch power to external field devices
• Optical isolators prevent electrical noise from affecting PLC logic
• Status LEDs reflect the current state of each output channel

Installation Requirements:

• Install in MEMOCON-SC series PLC rack with proper slot alignment
• Torque terminal screws to 0.5 Nm to ensure reliable connections
• Ensure proper wire gauge (0.5 mm² to 1.5 mm²) for output circuits
• Separate output wiring from high-voltage power cables to reduce noise
• Connect common terminals properly for each output group
• Ground module chassis to system ground

Usage Notes:

• Do not exceed rated contact voltage and current specifications
• Inductive loads require surge suppression components to extend contact life
• Do not wire input signals to output terminals
• Disconnect all power before wiring or module replacement
• Periodically inspect terminal connections for tightness
• Do not use in environments with explosive gases or conductive dust
