    This module has no power contacts. For field supply to downstream I/O modules, a supply module will be needed. The analog input module 750-461 and its variations can be used with all couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -323, -324 and -327). 2.1.2.4 Display Elements...

    Some fieldbus systems can process input channel status information by means of a status byte. This status byte can be displayed via the WAGO-I/O-CHECK 2 start-up and diagnostic tool. However, processing via the coupler / controller is optional, which means that accessing or parsing the status information depends on the fieldbus system.
