Terminal connection
4 to 20 mA DC input (Model VY5430F00XX)
Note: Terminals 2, 5, and 7 are connected inside the actuator.

mA DC input type)
Connection example
4 to 20 mA DC input (Model VY5430)
Note: Terminal 2 (power), terminal 5 (4 to 20 mA DC input), and
terminal 7 (2 to 10 V DC output for position feedback) are
connected inside of the unit
*1 Actuator's input impedance of 4 to 20 mA DC input is 100
.
4 to 20 mA DC input is not isolated, install a power
transformer individually.

A power supply commonly used
Note: When a power transformer is commonly used
When a power transformer is commonly used for two
ACTIVALs, be sure to match the polarity of each actuator's
terminal
and the polarity of the transformer. For the
terminal
, do the same as for the terminal
.
If the terminal is incorrectly connected, the product might be
damaged (see the figure above).
*1 Attach it when the controller side is not isolated.
*2 The
terminal
