Do not use any contact spray. The spray may impair the functioning of the contact area. The WAGO-I/O-SYSTEM 750 and its components are an open system. It must only be assembled in housings, cabinets or in electrical operation rooms. Access must only be given via a key or tool to authorized qualified personnel.
This module has no power contacts. For field supply to downstream I/O modules, a supply module will be needed. The analog input module 750-454 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).

Some fieldbus systems can process input channel status information by means of a status byte. This status byte can be displayed via the starting tool WAGO-I/O-CHECK 2. However, processing via the coupler / controller is optional, which means that accessing or parsing the status information depends on the fieldbus system.
• 13 Process Image 2.1.1.7.2 Special Data Format To digitalize the measurement value, the variation 750-454/000-002 uses another resolution as the standard module. For this variation, the input current ranging from 4 mA to 20 mA is scaled on the numerical values ranging from 0x0000 to 0x0F99.
