Product information of Autonics M4W2P-AAR-3 digital ammeter
M4Y, M5W, M4W, M4M (Ammeter) Series - Digital Ammeter (for ammeter)
The M4Y/M4W/ M5W/M4M series Ammeters can measure current in Ampere units and display the value in digital form.
These series have a display that displays RMS or AVG values based on user preference (AC voltage) in the form of a 7-segment LED.
The Ammeters have many user-friendly features including auto zero and hold functions (except M5W).
The device can be conveniently installed thanks to the standard DIN rail size.
