APM-MAX Large Digital Panel Meter for Process Signals or Power
APM-MAX-M23
The Trumeter APM-MAX-23 Process digital panel meter is a large digit display, multi-colour RGB back-lit LCD panel mount meter for 4-20mA, 0-10V, and current shunt inputs with Ethernet and RS485 for Modbus TCP Modbus RTU. An innovative, easy to set up, programmable panel meter providing highly visual indication of your critical parameters with interface to external control systems via communications. The APM-MAX-M23 has been specifically designed for engineers requiring a more effective way of monitoring and displaying process data. The Trumeter APM series digital displays are revolutionising the future of panel meter
APM-MAX-M23: for low voltage applications; configurable as a process meter (4-20mA, 0-10V) or to be used in conjunction with a shunt.
APM-MAX-M21: for high voltage applications; configurable as an ammeter, volt meter, frequency meter or power monitor (Watts, VA & Power Factor)
Designed for a wide range of monitoring applications, the APM-MAX combines the instant visual representation
of an analog meter with the speed and accuracy of a digital meter for instant recognition and precision measurement.
The large 81.5mm x 66mm display features a two-line display, programmable scale, alarm set-points and colour changing, full color RGB backlight for instant alerts.
