Non-Voltage Inputs; Solid-State Input (Npn Transistor); Voltage Inputs; Rotary Encoder Input - Omron H7CR-A Series Manual

H7CR
CONNECTIONS
The inputs of the H7CR are non-voltage (short circuit or open) inputs and voltage inputs. (Non-voltage inputs only H7CR-S, -8 and -11.)

Non-voltage inputs

Solid-State Input (NPN transistor)

Sensor
Counter
12 or 24 VDC
CP1, CP2
(reset), etc.
Input use 0 V
Input signal Ratings
Non-contact input High level when transistor is ON
Residual voltage: 2 V max.
Impedance when ON: 1 kΩ max.
Low level when transistor is OFF
Impedance when OFF: 100 kΩ max.
Contact input Use contacts capable of switching 2 mA at 5 VDC
