The Colorlight iM9 multifunction card adds environmental monitoring, automatic brightness adjustment and remote power control to a Colorlight LED display system. Its eight relay switches let operators control display power and supporting equipment from computer software.
Monitoring and Remote Control
The iM9 supports temperature and humidity monitoring, with optional smoke monitoring. Ambient brightness detection enables automatic screen brightness adjustment. Four switches are assigned to the LED display, while four serve air conditioning, fans or other switching functions; temperature-based automatic control is supported.
Audio transmission works in conjunction with the sending device. The automatic power-off function turns the display off when the sender signal is lost and back on when the signal returns.
