Digital DC Drives are great for applications where you need to accurately control your processes and need the advantages of DC drives and closed loop DC Drive PID. This video breaks down the family of DC drives to help you figure out which one best suits your needs. It also covers option cards and the digital potentiometer.

AutomationDirect has a variety of Digital DC Drives but sorting through the datasheets to figure out which one you need is tedious. So here is a concise feature matrix to help you decide which one is best for your application. There are 5-amp and 10-amp drives. And the only real differences are: this 5-amp drives doesn’t support option cards, has reduced alarm capabilities, and supports a lower sensor pulse rate. Other than that, you just choose what form factor you want: eighth DIN, quarter DIN or wall mount, and if you want the option cards pre-installed or not. Having those options cards pre-installed saves you the trouble of installing them yourself and the bundle costs a little less. By the way, you CAN install both option cards in one drive. All these drives automatically accept the full input power range without jumpers. They all support both 90 and 180 Volts DC output. They are all NEMA 4X rated. They all have closed loop control. They all support alarming. And they all support all three modes of operation. Notice that this guy isn’t really a drive. He’s called a Digital Potentiometer, but really, he’s identical to these drives, except instead of controlling a motor directly, he controls an off-board drive which controls the motor, which is really cool because it means you can turn an old analog open loop drive that you have very little control over, into a closed loop system so you can accurately control your DC motor! And, that also means you can operate this guy as either closed loop or open loop! The analog option card has a 4-20 milliamp input, a 4-2 milliamp output, a digital input and a relay output which you would typically use for alarm reporting. And while this is primarily a serial communications card, it also has a versatile analog input, a digital input and a frequency generator output.
