NX-series Load Cell Input Unit NX-RS CSM NX-RS DS E 6 1 Build a cost saving weighing/ measurement system by using load cells Converts the output signals from load cells into physical units such as weight or force and outputs them to the communications master NX-RS1201 Features Sampling as fast as 125 s Accuracy applicable to high-precision load cells (nonlinearity: 0.01% (full scale), zero drift: 0.1 V/C RTI, gain drift: 10 ppm/C) Screwless clamping terminal block for easy wiring. Push-in connections speed up installation Stable measurements with digital filtering (digital low-pass filter, moving average filter 1, and moving average filter 2) Optimum digital filter design using data tracing Cable disconnection check using sensor disconnection test TM Connection to the CJ-series is possible by connecting with the EtherNet/IP Coupler.
