Product Description

​The Omron K3MA-J-A2 is a versatile process meter designed to display and monitor DC voltage and current inputs in industrial applications. It features a highly visible LCD with dual-color (red and green) LEDs, enhancing readability under various lighting conditions. Equipped with two SPST-NO relay outputs, the K3MA-J-A2 facilitates process control by enabling users to set upper and lower limit alarms. Its compact 1/8 DIN size (96 x 48 mm) and user-friendly front-panel key operation simplify installation and configuration. Additionally, the device offers scaling, forced-zero, zero-limit functions, and average processing to suppress flicker, ensuring accurate and stable readings.
