I’ve made various projects using prototyping programmable controllers (like Arduinos) in the past, but I’m working on something now that will be in the industrial setting. I want to use an industrial controller having the components mounted on a din rail. In some situations this will simplify things— some components needed 24V and I had to use transistors to handle the higher voltage. But there’s one thing I can’t find a product for:
A din rail mounted power mosfet.
(The title of the post makes it sound like I’m calling a mosfet a prototyping component. I’m not.)
The project has a small resistance heater. At 24V, I’ll need to limit the current to 1A. The controller will monitor the temperature and limit the current accordingly (from 0-1A). I was thinking I could connect an analog output logic pin to a MOSFET to limit/control the current going to the heater (nichrome wire.) Why can’t I find any din rail mounted mosfets? I can find solid state relays and octocouplers, but I don’t think that’s what I need, and all of them have fairly high minimum output voltages (5V).
What am I missing here? I could make a circuit and put it in an enclosure, but I expected to be able to buy it readily.
