The ABB Pluto O2 (2TLA020070R8500) is a compact safety PLC output module designed to expand the failsafe output capability of ABB Pluto machine safety systems. As part of the ABB Pluto programmable safety controller range, it communicates over the Pluto Safety Bus and provides additional monitored inputs and failsafe relay outputs for industrial machinery and automation safety applications.
The Pluto O2 provides 6 I/O, comprising 2 failsafe inputs for monitoring, 2 configurable non-failsafe outputs/failsafe inputs and 2 individually failsafe relay outputs. Each failsafe relay output provides three contacts, making the module particularly useful where additional safety-related switching outputs are required within a Pluto-based safety system.
Operating from a 24 V DC supply, the Pluto O2 features screw connections and DIN-rail mounting for straightforward installation inside industrial control cabinets. Its compact 84 × 45 × 120 mm dimensions and integration with the Pluto Safety Bus make it an efficient way to extend the output capability of distributed machine safety installations.
Safety output modules such as the ABB Pluto O2 extend the switching capability of a programmable machine safety system without requiring a separate standalone safety controller. Its monitoring inputs and failsafe relay outputs allow additional safety-related equipment to be incorporated into a Pluto installation while retaining communication through the common safety bus.
The Pluto O2 is particularly suited to distributed safety architectures where additional relay outputs are required away from the main Pluto controller. Integration through the Pluto Safety Bus allows machine builders and automation engineers to develop flexible safety systems for machinery, production lines and automated manufacturing equipment.
