Connection to Analog Command Signal

P V T
Input voltage tolerance range is ±10 V. For input circuit impedance, see the figure below.
For the command circuit configuration with a variable resistor (VR) and a resistor (R), (VR)
must be 2 kΩ (1/4 W or more) and (R) must be 100 Ω to 200 Ω (1/4 W or more), so that
command input voltage range is -10 V to +10 V.
Be sure to use shielded twisted-pair cables as a noise countermeasure.
■ TIP
Isolation/non-isolation of the host analog command circuit and 24 V control power
If isolated
Connect A-GND with signal ground of the host controller. (Do not connect to GND of
control power)
If not isolated
Connect A_GND with GND of control power.
