The CD101 is an inexpensive (under $40) PID controller sold by Sure Electronics. Aside from the incomplete documentation that is shipped with the unit, I’m pretty happy with this controller. I’m planning to use it to replace the failed PID controller that controls my soldering hotplate.
I am having one small issue with the CD101 – stop mode doesn’t seem to do anything. By that I mean it doesn’t disable the outputs or seem to affect the controller in any way. Based on my interpretation of the user manual, the outputs and alarms should be disabled in stop mode. This is mostly an annoyance in my application – if I want to disable the hotplate I’ll just turn it off. However, I can imagine that the lack of a standby mode might cause problems in some applications.
I contacted Sure Electronics about the problem, and they requested a video. I figured I might as well post it here, since I went through the trouble of making it and everything. 🙂
By the way, since it can be hard to find information on this controller (eg. how to change from Fahrenheit to Celsius display), I have been slowly putting together a wiki page for the CD101.
PS: The video was shot with my new Canon PowerShot S95, which seems to take great footage, except that there is no autofocus or zoom control while shooting. (?!)
