H7CX-R

@-N

• Tachometer-only model (DIN 48

× 48) for the H7CX

(Supports display and alarm outputs for numbers of rotations, speed, and

flow rate.)

• Socket design allows either flush or surface mounting.

• “-W” models added for control with two independent measurements.

• Operation in any of the four following modes is possible with the same Unit:

Upper and lower limit, upper limit, lower limit, and area.

• Equipped with auto-zero time, average processing, and startup time functions.

Specifications

Ratings

*1. Do not use the output from an inverter as the power supply. The ripple must be 20% maximum for CC power.

*2. The display is lit only when the power is ON. Nothing is displayed when power is OFF.
