• Analog inputs and outputs
• For solving even complex tasks with analog process signals
• For connecting analog actuators and sensors without additional measuring amplifiers
  

HART modules

• For the use of HART (Highway Addressable Remote Transducer) devices in the SIMATIC S7 and PCS 7 automation systems
• All transducers or HART sensors/actuators which are certified for communication using the HART protocol can be connected
• In addition, conventional transducers with 4 to 20 mA technology without HART protocol can also be connected
• Can only be plugged into ET 200M with IM153-2

For details on HART modules, see "ET 200M distributed I/O station".
