Frequently Asked Questions
Why buy Unitronics from LED Controls?
We help you choose between UniStream, Vision, Samba or Jazz based on duty, I-O and networking. Expect fast delivery, clear documentation and responsive aftercare.
Is the programming software free?
Yes. Unitronics provides free programming environments that reduce project costs and make updates straightforward.
When should I choose an all in one PLC plus HMI?
Choose all-in-one when space is limited or you want faster builds. Separate PLCs and HMIs suit larger plants that need distributed architectures.
Can I expand I-O later?
Yes. Expansion modules cover digital, analogue, temperature and more so you can scale as requirements grow.
Do Unitronics drives work with Unitronics PLCs?
Yes. Drives integrate smoothly with Unitronics controllers and HMIs for unified control and monitoring.
