The ABB Pluto B42 AS-i is a programmable safety controller (Safety PLC) that combines the Pluto safety bus with AS-Interface (AS-i) bus communication. With 42 total I/O points, it features 20 failsafe inputs, 16 failsafe inputs/non-failsafe outputs, 4 individually failsafe relay outputs, and 2 individually failsafe transistor outputs. The Pluto B42 AS-i can operate as an AS-i master, slave, or safety monitor on an AS-i bus, supporting up to 31 safety slaves. It connects to other Pluto units via the CAN-based Pluto safety bus, enabling large distributed safety systems with up to 32 Pluto controllers.
