Key Panel


Key panels accept user information through standard, capacitive or inductive buttons and sends it to the Programmable Logic Controller (PLC). There is feedback on button event visual, audible or haptic.

  • Texas Instruments supports mechanical buttons, inductive buttons through inductance-to-digital converter, and capacitive buttons by the CapTIvate™ technology embedded in MSP430 microcontrollers
  • Button-press feedback by multi-channel LED driver, audio amplifier and piezo haptic drivers from Texas Instruments
  • Input voltage of up to 24V is transformed to lower voltages using high-efficient DC/DC converter or LDOs from Texas Instruments broad power portfolio
  • Interface to the PLC is Industrial Ethernet available in Sitara™ microcontrollers, or USB
