ماژول ورودی آنالوگ ABB مدل AI931N (AI4H)، کد فنی 3KDE175513L9310

The remote S900 I/O system can be installed in non-hazardous areas or directly in Zone 1 or Zone 2 hazardous area depending on the selected system variant. S900 I/O communicates with the control system level using the PROFIBUS DP standard. The I/O system can be installed directly in the field, therefore the costs for marshalling and wiring are reduced.
The system is sturdy, error-tolerant and easy to service. Integrated disconnection mechanisms allow replacement during operation, meaning that there is no need to interrupt the primary voltage in order to exchange the power supply units.S900 I/O type N. For installation in safe (= non-hazardous) area.AI931N Analog Input (AI4H), passive inputs for 0/4…20 mA.
