Yokogawa Electric Corporation 288114EMEM8JAA DC Ammeter

The Yokogawa 288114EMEM8JAA DC Ammeter is an analog panel meter (DC ammeter) with a center-zero 500-0-500 A measurement range and a 60-0-60 A secondary scale, driven by an external shunt. Designed for high-current DC monitoring, it is commonly installed in switchgear, battery banks, DC power supplies, rectifier systems, electroplating operations, and power distribution panels to show bidirectional current in real time. It uses a moving coil movement (typical taut-band or pivot design) inside an industrial-grade panel-mounted housing with a clear analog needle display. Common replacements include Yokogawa 254320RLRL8 and other 288114EMEM-series meters, and the unit is listed as a legacy/surplus industrial component.
