NV3-Series HMIs are sized for pairing with micro PLCs and compact ac drives or servo systems in small machines, allowing a machine builder to use the current choice of PLC model without redesigning an existing system. The 3.6-in. HMIs come with USB ports. Models with 3.6-in. color and monochrome screens (NV3Q) offer high-resolution QVGA (320 x 240 pixels) touchscreen displays. Models with 3.1-in. monochrome screens (NV3W) offer three-color backlighting and 64 x 128 pixel resolution.
