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.
