The ABB ABB pluto s20 v2 abb safety controller 2TLA020070R4700 is a compact and powerful programmable safety controller (Safety PLC) designed for machine-safety applications. Part of the ABB Pluto programmable safety controller range, the Pluto S20 v2 combines extensive safety functionality with a space-saving 45 mm-wide housing for installation in industrial control panels.
The Pluto S20 v2 provides 20 total I/O, comprising 8 failsafe inputs, 8 configurable non-failsafe outputs/failsafe inputs, 2 individually failsafe relay outputs and 2 individually failsafe transistor outputs. Its configurable I/O architecture allows numerous safety devices to be connected directly while helping reduce the quantity of separate safety components required within a machine-control system.
Operating from a 24 V DC supply, the Pluto S20 v2 is programmed using ABB Pluto Manager software. This S20 version is supplied without the Pluto safety bus, making it particularly suitable as a compact stand-alone safety controller for machinery requiring sophisticated programmable safety logic and substantial local I/O capacity.
The ABB Pluto platform provides a programmable alternative to implementing complex safety systems entirely with individual safety relays. Compatible emergency stops, guard switches, non-contact safety sensors, light curtains and other machine-safety devices can be incorporated into programmable safety logic, helping simplify control architecture on machinery with multiple safety functions.
With 20 total I/O in a housing only 45 mm wide, the Pluto S20 v2 provides a strong combination of functionality and panel-space efficiency. Its configurable channels and four individually failsafe outputs make it suitable for compact to medium-sized machines requiring flexible local safety control without the Pluto safety bus.
