Amazing Flexibility

"This must be the only such controller where a terminal can be used to drive a 1A load or read a low-level analog signal with full protection. We do a lot of different systems, so having 16 configurable IO terminals sure beats having 8+8 (or any other fixed combination) of single type ports."
No-Code is for Real

"We were quite skeptical about the no-code promise but it really works. We were able to build our application with just a few prompts and minor tweaking of the source code. Impressive time saver."
Incredible Support

"The Erqos folks know their stuff. We had a communication issue between the EQSP32 and a noisy motor controller. The kind of problems that vendors would normally point to faults on the other guy's product. They helped pinpoint the root cause and gave us a working solution. Thanks guys."
Painless WiFi Connection

"Allowing easy WiFi SSID and Password setup and change has always been more work than I cared for. Erqos' library and smartphone app makes it a zero-effort thing. Great job, team!"
Simple Ideas Make All the Difference

"Like being able to connect the PC via USB, using a standard cable and without taking the electrical cabinet cover off. Hard to believe that nobody thought of that before on a DIN-mount Micro-PLC."
