Digital expansion unit is a programmable controller to expand the system scale of a unit, its characteristics and use scenarios can be summarized as follows:

Definition and functions:

The DSDX453 Digital expansion unit is a device used to increase the number of input and output points of a programmable controller (such as PLC) system.

It cannot be used alone. It needs to be connected to the host through an expansion port to expand the functions of the system.

Application scenario:

DSDX453 When the control object needs more control points than the PLC host I/O points, it is necessary to use a digital expansion unit to increase the input and output points.

In industrial automation production, security monitoring systems, automated measurement and control systems, digital expansion units are particularly widely used.

Specific needs and solutions:

In some special cases, such as when the peripheral feedback voltage is higher than the PLC feedback voltage, it may be necessary to use a relay to protect the PLC I/O port.

The relay isolation requirements for I/O signals can also be achieved through digital expansion units to avoid damaging the PLC’s I/O ports.
