Applicable Industries:

• Sensor interface (proximity, photoelectric, inductive)
• Switch and pushbutton monitoring
• Encoder signal input (A/B/Z channels)
• Safety door interlock monitoring
• Conveyor belt presence detection
• Valve position feedback

Installation Requirements:

• DIN rail 35 mm (EN 60715)
• Wire size: 0.14–2.5 mm² copper conductors
• For PNP mode: connect sensor output to input terminal, sensor common to 0V
• For NPN mode: connect sensor output to input terminal, sensor common to +24V
• Minimum 10 mm spacing between modules

Usage Precautions:

• Do not exceed 30V DC on any input terminal
• Do not apply AC voltage to digital inputs
• For long cable runs (> 10 m), enable input filter to suppress noise
• Verify PNP/NPN configuration matches field device type before power-up
• Do not leave unconnected inputs floating — tie to defined logic level

Advantages & Highlights:

• 16 channels in a single 45 mm module — high channel density
• Configurable PNP/NPN per group — one module covers both sensor types
• Adjustable input filter eliminates false triggering from noisy environments
• Full diagnostic capability (wire-break + short-circuit) per channel
