INTELLIGENT ACTUATOR
This unit connects to a multi-point DIO board for X-SEL controller type K (general-purpose type) and
divides the power supply into multiple external interface circuits. This unit cannot be used with X-SEL
controller type J (compact type).
Separate interface circuits are provided for six DI/DO groups (each group consisting of eight points). This
allows for separate wiring of interface power supplies for external I/O equipment.
1. Overview
1.1 Features
[1] Dividing the DIO interface power supply (24 VDC) into 12 groups
This unit has built-in insulated DIO interface circuits for six input groups (each group consisting of
eight points) and six output groups (each group consisting of eight points).
[2] Conversion from one half-pitch flat connector to three MIL flat connectors
A multi-point DIO connector for 48 DIs/48 DOs can be divided into three I/O connectors each
providing 16 DIs/16 DOs.
[3] Support of DO large-current output specification
This unit has a transistor buffer circuit to support an output current of 500 mA per point (0.8 A per
eight points).
[4] Support of NPN and PNP DIO interfaces
Both NPN and PNP-type DIO interfaces are supported (the supported interface specification is set
before shipment). With both the NPN and PNP units, the connected controller DIO board must be of
NPN type.

[3] LED indicators
This unit has LED indicators that show the DO power-input status for each connector.
If external power is not input or a fuse on the board is blown, the applicable LED will turn off.
All fuses are resettable (meaning that the fuse will reconnect automatically once an overcurrent
condition is removed). One fuse is provided for each group of eight DOs.

[4] External power-supply open detection switch (SW1)
This unit is capable of outputting a detection signal indicating absence of external DO power supply (24
VDC) to the X-SEL controller.
To use this function, the dedicated switch (SW1) must be set to the ON position.
In the power-supply open detection mode, IN47 becomes a dedicated input for detection signal.
The applicable X-SEL controller parameter must also be set to specify error detection input for the
terminal block unit.
I/O parameter No. 23: Specification of overcurrent/power-supply error detection input for multi-point
DIO external terminal block
Example 1) To detect power-supply open failure only for the unit connected to the multi-point I/O
board in expansion slot I/O1 (I/O2), set I/O parameter No. 23 to “20.”
Example 2) To detect power-supply open failure for both units connected to the multi-point I/O
boards in expansion slots I/O1 (I/O2) and I/O2 (I/O3), set I/O parameter No. 23 to “220.”
If you want to use IN47 as a normal general-purpose input instead of an open-failure detection signal,
be sure to set the switch to the OFF position.
