EC: Pluto D45 Safety PLC

Safety - Machine safety: A safety PLC used for the automation and control of machine safety systems in a variety of industrial applications including presses, packaging systems, robotic cells, injection molding machines, assembly lines, conveyors, food processing, and other uses. This is a Control Engineering 2013 Engineers' Choice Awards Honorable Mention.

Pluto is an “all-supervisor” system in which the inputs and other information are shared via the databus, providing simplified design and the highest level of safety. The key difference between Pluto and conventional safety PLCs is that there is no "supervisor-subordinate" relationship between the units connected to the safety bus. Each Pluto is a “supervisor” unit and can see the other Pluto’s inputs and outputs. Several safety sensors can be connected to one input while still achieving the highest level of safety. The flexible, scalable and modular design allows the system designer many options when designing safety systems. Pluto has inputs for all safety devices on the market, and the Pluto Manager software selects how each input shall respond.

The Pluto D45 Safety PLC provides more ease of use functionality than other models available on the market. With software included, and a hot back-up feature that allows users to reprogram the unit and get a machine up and running with just a screw driver and a pen. The D45 has 39 safe inputs which can handle 380 devices (10 per point) and 6 Cat 4/PLe stop conditions allowing users to do much more with far less. The Pluto Pluto D45 is equipped with 8, safe 4-20 mA/0-10 V analog inputs. These (IA0–IA7) can be configured as either “ordinary” failsafe inputs, or analog inputs 0-10 V/4-20 mA. Inputs IA0–IA3 can be configured as counter inputs (pulse counting), which work for frequencies up to 10,000 Hz. As counter inputs IA0–IA3 can be used in two ways, up counting or up/down counting. In addition to railroad crossings, Pluto PLCs also have been used for many unique applications like winch control for the acrobats in Cirque du Soleil and for the opening ceremony of the 2012 Summer Olympics.
