P854 3BSE025349R1 ABB Power supply and communication management module AC 800M S800 I O
P854 3BSE025349R1 ABB Power supply and communication management module AC 800M S800 I O
ABB P854 is the power and communication management module in the S800 I/O system, specifically designed for the TB854/TB855 redundant I/O baseboard. It not only provides stable and reliable + 5V and ± 15V logic power supplies for the connected DI/DO/AI/AO modules, but also manages the ModuleBus communication bus to ensure efficient and reliable transmission of I/O data between the modules and communication interfaces (such as CI854A).
Core features
Dual independent power supply input
Supports two 24V DC power inputs (L+1 / L+2)
Automatic switching, uninterrupted power supply
Built-in reverse polarity protection and overvoltage/overcurrent protection
Provide full-specification power supply for I/O modules
+ 5V DC: For digital module logic circuits
+ 15V / -15V DC: For the signal conditioning circuit of the analog module
Total output power: Meets the demand of up to 12 S800 I/O modules
