Omron H7BX-A User Manual

6 Multifunction Counter H7BX
■ Input Connections
A no-voltage input (short-circuit or open) or voltage input can be selected for each input. (The key protection input is always a no-voltage
input (NPN input)).
● No-voltage Inputs (NPN Inputs)
Note: When the H7BX is used as a tachometer, the CP2 input and total reset/reset 2 input are not used.
No-voltage Input Signal Levels
Note: Use a DC power supply of 30 V max.
● Voltage Inputs (PNP Inputs)
Note: When the H7BX is used as a tachometer, the CP2 input and total reset/reset 2 input are not used.
Voltage Input Signal Levels
Note 1. Use a DC power supply of 30 V max.
2. Input resistance: Approx. 4.7 kΩ
