Advanced Features and Operational Benefits

• High-Density Industrial Design: 32 fully isolated digital input channels in a space-saving 35mm width form factor (98mm height × 55mm depth), enabling maximum I/O density for control panel optimization.
• Universal Input Configuration: Flexible sink/source input architecture supports both NPN (sinking) and PNP (sourcing) sensor connections at 24V DC nominal voltage (21.6-26.4V DC operating range).
• Precision Response Characteristics: Industry-leading 1ms OFF→ON and 2ms ON→OFF response times ensure accurate monitoring of high-speed processes and rapid state changes.
• Enhanced Electrical Protection: Photocoupler isolation (1,500V AC for 1 minute between field inputs and internal circuits) provides superior noise immunity and protection against voltage transients.
• Tool-Free Wiring System: Patented screwless clamping terminal block accepts 0.3-2.5mm² wires (AWG 22-12) without special tools, featuring clear polarity markings and secure retention.
• Robust Power Performance: Wide voltage tolerance (±10% of nominal 24V DC) with low 3mA typical input current and 1.8W power consumption for energy-efficient operation.
• Industrial Environmental Ratings: Operates reliably in 0°C to 55°C temperatures with 10-95% RH non-condensing humidity, resistant to vibration (10-150Hz) and shock (147m/s²).
• Manufacturer Warranty: Backed by Omron's standard 1-year limited warranty covering defects in materials and workmanship (proof of purchase required).

Industrial Automation Applications
