Part 1 Installation
3. Multipoint DIO Board
This board is a multipoint DIO board for XSEL controllers on which 48 input points and 48 output points
are provided.
3.1 Overview
3.1.1 Features
[1] 96 points can be input/output using a single board.
One board provides 48 input points and 48 output points to enable multipoint I/O control with your
XSEL controller.
[2] PNP/NPN DIO interfaces are supported.
As with other current IO boards, two types of DIO interfaces–NPN and PNP–are available.
[3] Overcurrent & I/O power monitor functions
The DO board is monitored for overcurrent and IO power-supply voltage and if an overcurrent is
detected or the specified voltage is exceeded, DO outputs are cut off. Take note, however, that unlike
with current IO boards, the overcurrent detection is performed based on 400 mA/24 points. (Current
IO boards: 400 mA/8 points)
