Yokogawa Electric Corporation 255-424-ECNT Analog Panel Meter

The Yokogawa Electric Corporation 255-424-ECNT Analog Panel Meter is a panel-mounted ammeter that measures DC current via an external shunt (mV signal input). As part of Yokogawa's 255 Series, it is used in electrical measurement systems such as switchgear, control panels, and power distribution setups that require precise current indication. The device typically provides a ~50 A full-scale rating (model-dependent) and features an analog needle display with accuracy typically ±2–3% of full scale. It is built in an industrial-grade housing and complies with ANSI C39.1, making it suitable for installation in control panels across manufacturing plants, utilities, and automation environments where reliable, real-time current monitoring is required. Maintenance teams and system integrators use the 255-424-ECNT for replacement or retrofit of legacy equipment to maintain accurate current monitoring in DC circuits. Common replacements include Yokogawa 255-424-ECNL and 255-424-ECPB variants in the same series. This legacy/surplus component serves electrical current monitoring and protection applications in control panels and power distribution systems, delivering straightforward installation and a robust, industrial design.
