 ABB SS822 3BSC610042R1 Power Voting Unit The Voting Units SS822Z, SS823 and SS832 have been specifically designed to be employed as a control unitwithin a redundant power supply configuration. The output connections fromtwo Power Supply Units are connected to the Voting Unit. The Voting Unit separates the redundant Power Supply Units, supervises the voltage supplied, and generates supervision signals to be connected to the power consumer. Green LED’s, mounted on the front panel of the voting unit, provide a visual indication thatthe correct outputvoltage is being delivered. Simultaneously with the green LED illuminating, a voltage free contact closes the path to the corresponding “OK connector”. Voting Unittrip levels, are factory preset.Detailed data: Permitted supply voltage variation Mains frequency 60 V DC Primary peak inrush current at power-up Load sharing Two in parallel Power factor (rated output power) Heats dissipation 10 W at 20 A, 2.5 W at 5 A Output voltage regulation 0.5 V below input at maximum current Maximum output current (minimum) 35 A (overload) Maximum ambient temperature 60 °C Primary: external fuse recommended Secondary: short circuit Electrical safety IEC 61131-2, UL 508, EN 50178 Marine certification ABS, BV, DNV-GL, LR Protection class IP20 (according to IEC 60529) Corrosive environment ISA-S71.04 G3 Pollution degree 2, IEC 60664-1 Mechanical operating conditions IEC 61131-2 EMC EN 61000-6-4 and EN 61000-6-2Frequently asked questions about the product are as follows: -What are the functions of the ABB SS822 module? The ABB SS822 is a safety I/O module that provides an interface between the control system and safety-related field devices. It is responsible for monitoring and controlling safety-critical processes and equipment. It processes safety signals such as emergency stop buttons, safety switches and other safety devices and ensures that the system complies with functional safety requirements. -How many I/O channels does the SS822 module have? 16 digital input channels and 8 digital output channels are provided. These I/O channels are used to connect safety-related devices. The number of I/O channels may vary depending on the configuration and specific requirements of the safety system. -How does the SS822 module integrate with the ABB 800xA or S800 I/O system? Integrated with the ABB 800xA or S800 I/O system via Fieldbus or Modbus communication protocols. It can be configured using the ABB 800xA engineering tool.
