Rotation, Speed, and Flow Indicators/Direction Alarm Indicator K3MA-F

Caution
Product Description
Digital panel meter with 2-color LED backlight (red/green).
[Features]
· Highly visible due to a negative LCD display, and can be set easily with front key operation.
· Terminal cover equipped as standard for electric shock prevention; contact, NPN, PNP and voltage pulse inputs supported.
· Equipped with scaling, auto zero time and start-up compensation timer functions, as well as an averaging function for suppression of flickering.
· MAX/MIN display can be checked, and features a built-in (12 V DC, 40 mA) external power supply.
· The front panel has a waterproof and dust-proof structure compliant with protective structure NEMA4X (IP66 equivalent).
· CE marking compliant and UL standard certified (mark license certified).
[Applications]
· Used as various indicators by receiving the rotation speed and flow rate speed through pulse input.
