Input voltage tolerance range is ±10 V. For input circuit impedance, see the gure below.
For the command circuit conguration with a variable resistor (VR) and a resistor (R), VR
must be 2kΩ (1/4W or more) and R must be 100 Ω to 200 Ω (1/4W or more), so that
command input voltage range is -10V to +10V.
Be sure to use shielded twisted-pair cables as a noise countermeasure.
■ Isolation/non-isolation of the host analog command circuit and 24V 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.
