NSA Automation supplies industrial automation products and engineering services to factories. Its main office is in Subang Jaya, Selangor, with a branch in Seremban. It carries sensors, PLCs, HMI touch panels, VFD inverters, servo drives and motors, and power supplies, from brands such as Inovance, Siemens, Mitsubishi, Omron, Weinview and Meanwell.
Alongside the parts, its engineers offer panel wiring, system upgrading, PLC and HMI programming, machine troubleshooting and parts sourcing. The idea is to cover a factory's needs from supplying a single component to setting up and maintaining the system around it.
