h7cx-a114-n Omron Corporation, h7cx-a114-n Datasheet - Page 37

• Manufacturer Part Number: h7cx-a114-n
• Description: Multifunction Counter/tachometer
• Manufacturer: Omron Corporation

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.
• Tachometer-only model (DIN 48
• 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:
• Equipped with auto-zero time, average processing, and startup time functions.
