• 2, 4 and 8-channel analog input (AI) 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 output modules offer:

• Function classes Basic, Standard, High Feature and High-Speed
• 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)
• Option of connecting current, voltage and resistance sensors, as well as thermocouples
• Energy Meter for recording up to 200 electrical variables
• 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)
  • Oversampling operating mode (n-fold equidistant acquisition of analog values within one PN cycle for increasing the time resolution for slow CPU cycles)
  • Isochronous mode (simultaneous equidistant reading in of all analog values)
  • Scalable measuring range (adaptation of measuring range, increase of the 16-bit resolution by adapting the measuring range to a limited section)
  • Scaling of the measured values (transmission of the analog value normalized to the required physical value as a 32-bit floating point value)
  • Internal compensation of the line resistance for thermocouples by means of terminal temperature measurement in the BaseUnit for BU type A1
  • Internal compensation also for 2-conductor resistance measurement by means of adjustable line resistance
  • Calibration during runtime
  • Single-channel electrical isolation
  • HART communication
  • Re-parameterization during operation
  • Firmware update
  • Diagnosis of wire break, short circuit, overflow, underflow
  • Two upper and lower hardware interrupts in each case, interference frequency suppression, smoothing
  • Value status (optional binary validity information of the analog 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 AI modules is offered by the TIA Selection Tool.
