£1,273.57
The ABB Pluto A20 v2 (2TLA020070R4500) is a compact and powerful programmable safety controller (Safety PLC) designed for machine safety applications and the control of safety-related devices. As part of the ABB Pluto safety PLC range, it combines configurable safety I/O, failsafe outputs and Pluto safety bus communication in a compact controller for industrial machinery and automation systems.
The Pluto A20 v2 provides a total of 20 I/O, comprising 8 failsafe inputs, 8 configurable non-failsafe outputs/failsafe inputs, 2 individually failsafe relay outputs and 2 individually failsafe transistor outputs. It also provides current monitoring on outputs Q16 and Q17, enabling flexible implementation of machine safety functions.
Operating from a 24 V DC supply, the Pluto A20 v2 supports connection of a wide range of safety devices and can be programmed using ABB Pluto Manager software. Its compact 84 × 45 × 120 mm enclosure and Pluto safety bus capability make it particularly suitable for distributed and networked safety control within industrial machinery.
Programmable safety controllers such as the ABB Pluto A20 v2 provide a flexible alternative to implementing complex machine safety functions with multiple individual safety relays. Safety sensors and other protective devices can be connected to the controller, while configurable inputs and outputs allow the safety system to be adapted to the requirements of the machine.
The Pluto platform is designed for industrial machine safety and supports communication through the Pluto safety bus, allowing multiple controllers and safety functions to operate within a coordinated safety system. Programming with ABB Pluto Manager enables machine builders and automation engineers to develop and maintain application-specific safety logic.
