Mô tả
The UMA4 is a high-accuracy, 4-digit multi-purpose digital panel meter featuring a high-brightness red LED display for clear and fast readings. It supports a wide range of input signals, including voltage, current, resistance, thermocouples, PT100, and load cells. Optional functions include relay alarm outputs, analog outputs, and RS485 communication with Modbus RTU protocol, making it ideal for industrial automation systems. With EEPROM memory, push-button configuration, and flexible alarm control, the UMA4 is widely used in pressure, temperature, flow, energy, and environmental monitoring applications.
