OverviewThe Omron NX-RS1201 Load Cell Input Unit offers a cutting-edge solution for precise data acquisition within various industrial settings. Designed as an integral part of the Omron NX Series I/O architecture, this unit capably transforms analog signals from load cells into accurate digital readings for weight and force. This functionality is essential for immediate data capture, leading to improved operational efficiency, rigorous quality assurance, and intelligent automation. Featuring a sophisticated 24-bit analog-to-digital converter and an exceptionally rapid 125 µs conversion time, the NX-RS1201 guarantees highly dependable and accurate measurements.Key Features Rapid Conversion Cycle: Achieves a swift conversion speed of only 125 µs, enabling quick data capture vital for dynamic industrial workflows and real-time operational control. Outstanding Measurement Accuracy: Benefits from a mere ±0.01% full scale nonlinearity, a minimal zero drift of ±0.1 µV/°C RTI, and a low gain drift of ±10 ppm/°C, ensuring consistent and precise measurements across various environmental conditions. Superior 24-bit Resolution: Provides exceptional detail and accuracy when converting analog load cell signals into digital format, capturing even the smallest variations. Consistent Excitation Voltage: Supplies a stable 5 VDC ±10% excitation voltage to connected load cells, with a maximum current output of 60 mA, ensuring reliable sensor operation. Flexible Calibration Options: Offers broad adjustment ranges for zero and gain points from -5.0 to 5.0 mV/V, enabling meticulous calibration for specific application needs. Compact Form Factor: With a slender profile of 12 mm (W) × 100 mm (H) × 71 mm (D), this unit optimizes space within crowded control cabinets. Simplified Connectivity: Features screwless clamping terminal blocks for quick, secure, and straightforward connections, reducing both installation time and maintenance. IP20 Environmental Protection: Engineered to protect against solid particle ingress, making it suitable for deployment in typical industrial control environments. Technical Specifications Model Number: NX-RS1201 Input Range: -5.0 to 5.0 mV/V Input Conversion Span: -5.5 to 5.5 mV/V Load Cell Excitation: 5 VDC ±10%, 60 mA maximum Nonlinearity: ±0.01% of full scale Zero Point Drift: ±0.1 µV/°C relative to input Gain Drift: ±10 ppm/°C A/D Converter Resolution: 24 bits Conversion Interval: 125 µs Isolation: Input to NX bus isolated via transformer (power) and digital isolator (signal) Dimensions: 12 mm (W) × 100 mm (H) × 71 mm (D) Mass: 70 g maximum Protection Rating: IP20 Mounting Method: DIN rail Applications Advanced Weighing Systems: Essential for highly accurate weight determination in applications such as precision packaging, critical batch processing, and automated filling lines.
