Product Description
Trumeter APM-MAX-M21-PL-4R is a high-performance digital panel multifunction meter designed for measuring frequency, power, voltage, and current in industrial and process control applications. Featuring an innovative display that combines high-contrast digital accuracy with an analogue-style visual bar graph, this meter offers quick recognition and precise measurement in a compact 68 mm x 68 mm panel cutout format.
The meter supports configurable operation modes including ammeter, voltmeter, frequency meter, and power monitor measuring Watts, VA, and Power Factor. The display integrates a large 4-digit LCD (14.5mm digit height) with a 60-segment bar graph and a separate starburst area for displaying messages, alarms, and status information with full RGB backlighting. This allows immediate visual feedback in bright or diverse lighting conditions, enhancing usability on the factory floor or in control rooms.
Equipped with programmable scaling and range adjustment including min/max, offset, gain, centre zero, and nonlinear scaling, the APM-MAX-M21 enables tailored measurement for varied industrial signals. It features two independent alarm set points and outputs: two digital open collector outputs, one 4-20 mA analogue output, and serial MODBUS RTU communication for seamless integration with automation systems.
The device measures within operating temperatures from -10°C to 60°C and is protected with an IP65 rating for robustness in challenging industrial environments. Its compact design (108mm x 108mm face, 64mm depth) fits commonly used 2.7 inch square or 4 inch circular panel cutouts facilitating easy retrofit or new installations.
The meter is widely applicable across industrial automation, electrical distribution, process control, HVAC monitoring, and laboratory applications requiring multi-parameter real-time monitoring in a single device. It supports remote monitoring when paired with Trumeter IoT Gateway and cloud services.
Configurable digital multifunction measurement of frequency, power, voltage, and current. Dynamic RGB backlighting with a large 81.5mm x 66mm LCD screen and bar graph. Two independent alarm setpoints with digital and analogue outputs.
Serial MODBUS RTU interface for system integration. Robust IP65 rating and wide operating temperature range (-10°C to 60°C). Compact panel mount design compatible with standard cutout sizes. Suitable for industrial automation, process control, and electrical systems.
