The L20000RMA4 ammeter is a digital measurement device built on a standard main board featuring high-visibility red LEDs. It is engineered with an isolated signal input designed specifically for a ±2.0000 mA range. For system integration, the unit features an isolated digital interface utilizing RS485 communication via dual RJ45 connectors. Output control is managed through four isolated 120 mA solid state relays. This model operates with an isolated power supply supporting a versatile voltage range of 85-264 Vac or 90-300 Vdc, making it well-suited for industrial measurement and control environments requiring precise current monitoring and robust galvanic isolation across its power, input, output, and communication interfaces.
