Explanation:
True, one advantage of discrete relay contact output modules is indeed that they can be used with both AC and DC devices.
Relay output modules are designed to switch both AC and DC load currents. Because they are not voltage specific, these modules can control a variety of devices regardless of their operating voltage. This versatility is one of their key advantages. The relay acts as an electrically operated switch allowing for control of the connected device, be it AC or DC. It is, however, important to ensure that the relay is rated for the voltages and currents of the devices it’s intended to control.
