The Schott iQ421 is billed as the flagship in flexible LED controllers for illumination of machine vision systems, yet has a very affordable price tag.
The Schott iQ421 controller is billed as the flagship in flexible LED controllers for illumination of machine vision systems, yet has a very affordable price tag.
Using unmatched proprietary features, this easy-to-use system has a two-line/16-character display permitting simple setup in four languages.
Operational parameters can also be set up via the RS232 interface.
The iQ421 automatically recognises and adjusts the LED head's maximum current requirements, monitors and controls its temperature, displaying overtemperature warning signals, and provides 0-100% intensity variation.
A light feedback loop maintains intensity to +/-2% regulating current to compensate for LED intensity degradation.
Trigger mode with programmable delays offers synchronisation to provide light output only when needed.
A 15Hz to 50kHz strobe feature offers freeze motion capability, remote switching enables on/off functions in any operating mode.
A simpler version the iQ121 controller offers automatic current and temperature control, high temperature warnings and manual intensity control.
