• 4, 8 and 16-channel digital input (DI) modules
• Apart from the standard delivery form in an individual package, selected I/O modules and BaseUnits are also available in a pack of 10 units. The pack of 10 units enables the amount of waste to be reduced considerably, as well as saving the time of unpacking individual modules.

For different requirements, the digital input modules offer:

• Function classes Basic, Standard, High Feature and High-Speed as well as fail-safe DI
• BaseUnits for single or multiple-conductor connection with automatic slot coding
• Individual system-integrated load group formation with self-assembling voltage distribution bars (a separate power module is no longer required for ET 200SP)
• Connection option of sensors compliant with IEC 61131 Type 1, 2 or 3 (module-dependent) for rated voltages of up to 24 V DC or 230 V AC
• PNP (sink input) and NPN (source input) versions
• Clear labeling on front of module
• LEDs for diagnostics, status, power supply and faults
• Electronically readable and non-volatile writable rating plate (I&M data 0 to 3)
• Extended functions and additional operating modes in some cases
  • MSI operating mode (simultaneous reading of input data from as many as three other controllers)
  • Counting operating mode (multi-channel counter for pulse generators with 32-bit counting width and up to 10 kHz counting frequency)
  • Oversampling operating mode (n-fold equidistant acquisition of digital values within one PN cycle for increasing the time resolution for slow CPU cycles)
  • Parameterizable input delay time
  • Isochronous mode (simultaneous equidistant reading of all input channels)
  • Hardware interrupts
  • Pulse extension
  • Re-parameterization during operation
  • Firmware update
  • Diagnosis of wire break and short-circuit (on channel or module basis)
  • Value status (optional binary validity information of the input signal in the process image)
  • Support of the PROFIenergy profile
• Optional accessories
  • Labeling strips (film or card)
  • Equipment labeling plate
  • Color-coded label with module-specific CC Code
  • Shielding terminal

A quick and clear comparison of the functions of the different DI modules is offered by the TIA Selection Tool.
