DC 220v Marine Digital Panel Ammeter 4-20ma Output Low Power Consumption
1. Overview
The WD-3ID Series is a line of ampere meters that measures current parameters. They are used for monitoring and controlling energy flow in DC systems.
Readings are displayed on the brilliant 4 digits LED display. All WDLYCH models offer integration with external systems using MODBUS RTU protocol and an on-board RS485 serial communication port.
Optional analog, digital, relay and alarm output is available via field-swappable plug-in communications modules.
The line has been field-tested for accuracy, versatility, durability.
