Pluto from ABB is an "All-Master" safety PLC concept, which simplifies the design of safety systems and achieves the highest safety category 4 according to EN 954-1. All Pluto's are Master units and can see the other Pluto's inputs, outputs and global memories. This enables the Pluto to evaluate the information from the other Pluto's and then take decisions concerning its own safety devices. The Gateway units are available for several different bus systems, i.e. Profibus (733-4836), CanOpen (733-4830), Devicenet (733-4849) and Ethernet (733-4842). Of Pluto's inputs (the smallest unit has 16 I/O), thus can be configured as either inputs or outputs. In the Pluto family by ABB most modules have dual safety outputs - potential free or PNP types. In a two-wire bus system up to 32 Pluto units can be safely connected and communicate with a superior system via a Gateway or HMI displays. Therefore within a maximum extended system 1472 I/O's can be connected. Also all input components may be connected in series for even more complexity and optimisation.

Simple and easy programming facilities
Easy to configure and install
Up to 640 I/O's
Multiple Plutos can be connected on a bus (via using the IDFIX identifier) and then further interfaced with external networks by using a Gateway, typical example RS stock number (733-4842)
High safety level
Free software available
Programming over the bus
35 mm DIN rail mounting
The IDFIX (733-4824) is an identification circuit which allows multiple Plutos to be identified when connected on a bus system. This module is available to distribute a PLC program within a network of Pluto devices.
Tina adapters such as (733-2477) can be used to connect external safety monitoring equipment

The IDFIX device (733-4824) is connected between the input terminals ID and 0V (also note that the IDFIX device is not required when using a single Pluto, however the absense of an IDFIX requires to be stated when programming the Pluto device.)

Control multiple safety systems from a single unit using this safety controller from ABB. It features 24 inputs and 16 outputs to accommodate a wide range of monitoring functions. This eliminates the need for multiple safety relays by offering an all-in-one control system for machine guarding in your industrial environment. You can connect this device to other safety controllers from ABB's Pluto range using the IDFIX identifier (733-4824). This lets it share information with other controllers to optimise its performance. As this component is configurable, you can adjust its settings to suit your specific application.

• DIN rail mounting for quick, tool-free installation
• Light weight of 0.65kg for reduced strain on system
• Contact current rating of 5.1A for energy-efficient operation

• Power generation plants
• Marine industry
• Chemical industry
• Food and beverage production
• Material handling system

A safety controller lets you connect and monitor numerous safety devices. Typically, a safety relay controls between one and three devices depending on whether it has a single-channel or multi-channel relay.
