CJ Power Supply Units for PLCs

The CJ system can work with a 24 V DC power supply or on a 100 – 240VAC mainline. For smaller-sized installations that mostly use digital I/O, there is no need to purchase an expensive one since they’re cheap anyway! But if you plan ahead and include plenty of analog inputs alongside control unit communications then make sure your larger capacity suppliers are available at all times because these types require more juice than what’s coming outta those small fuses under their hoods.
