Nematron IWS-120-EC Operator Interface Panel Workstation Terminal

The Nematron IWS-120-EC Operator Interface Panel Workstation Terminal is an industrial front-end designed to serve as a dedicated operator interface for automation systems. Part of Nematron's IWS (Industrial Workstation) family, it provides a compact panel terminal for local control, status display, and input on the factory floor. The unit runs on 90–250 VAC power, supports 50/60 Hz, and draws up to 1 A, with a typical weight around 5 lb, making it suitable for panel mounting or workstation setups. This IWS-120-EC is listed as discontinued by the manufacturer and is cross-referenced with other IWS models (1398-HMI-002, 9101-2017, 9101-2196), reflecting its historical role in the HMI/OP panel lineage. In the 110/120 series, the display is documented as 3.2 inches, offering concise visual feedback alongside straightforward key-based input; operator actions can be transmitted as ASCII codes to a PLC network, enabling basic control and monitoring without a separate industrial PC. Common applications include machine interfaces on manufacturing lines, assembly and packaging operations, and other processes that require a compact, rugged operator terminal connected to an automation network.
