ABB SA920N 3BDH000600R1 Power Supply.General info Article number:3BDH000600R1;Signal specification24 V d.c. (19.2 - 32 V d.c.);Signal typePower supply;RedundancyYes;Intrinsic safetyNo;MechanicsS900
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 PROFIBUS DP standard.The I/O system can be installed directly in the field, therefore the costs for mashalling 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.SA920N Power Supply for 24V DC, for redundant termination unit TU921N (TU16R) in S900 I/O. Do not mix SA910N with SA920N for redundancy (observe Release Notes).
