Tachometer H7CX-R 47
■ Input Connections
The inputs of the H7CX-R can be used as either no-voltage (short-circuit or open) inputs or voltage inputs. They are set for use as voltage inputs
at the time of delivery.
No-voltage Inputs (NPN Inputs)
No-voltage Input Signal Levels
Note: The DC voltage must be 30 VDC max.
Applicable Two-wire Sensor
Leakage current: 1.5 mA max.
Switching capacity: 5 mA min.
Residual voltage: 3.0 VDC max.
