3. Multi-point DIO Board
This board is a multi-point DIO board equipped with 48 input points and 48 output points for use with
XSEL controllers.
3.1 Overview
3.1.1 Features
[1] One board provides a total of 96 input/output points.
Multiple inputs/outputs of your XSEL controller can be controlled with a single board offering 48 input
points and 48 output points.
[2] Supporting DIO interfaces of PNP and NPN types
Just like you can with current IO boards, you can also select a desired DIO interface of one of two
types, NPN and PNP, for this board.
[3] Overcurrent & I/O power-supply monitoring function
An overcurrent flowing through the DO board is detected. The I/O power-supply voltage is also
monitored and if the monitored voltage deviates from the specified range, the DO outputs will be cut
off. Take note, however, that unlike with current IO boards, this board detects overcurrent based on a
threshold of 400 mA per 24 points (current IO boards: 400 mA per 8 points).
