• Digital input modules (DI)
• Digital output modules (DQ)
• Analog input modules (AI)
• Analog output modules (AQ)
• Technology modules (TM)
• Communications modules (CM)

Front labeling and color coding

The I/O modules are clearly labeled on the front which makes commissioning and servicing easier:

• Plain text labeling of the module type:
  E.g.: "DQ 16 x 24 V DC/0.5 A"
• Function class of the module: Basic, Standard, High Feature or High Speed
• 2D matrix code with article and serial number encoded. This ensures easy identification of the module and direct linking to the service page via Industry Support App
• Connection diagram
• Color coding of the module types DI (white), DQ (black), AI (light blue), AQ (dark blue), TM (turquoise), CM (light gray), special modules (mint green).
  Fail-safe modules are additionally identified by a yellow housing and an "F-" prefix on the plain text labeling.
• Function status of the hardware
• Firmware version
• Color code of the matching color coding plate for the process terminals of the module
• Article number of the module (for PU 1)
