Safety PLCPlutoApprovals:TÜV RheinlandControl of:Safety products in dynamicand static circuitsElectrically controlledactuators such ascontactors, valves, motorsIndicators and buttonsFeatures:Pluto Safety PLC facilitates the design of yoursafety systemsPluto is an All-Master system for dynamic and static safetycircuits where inputs and other information are shared overthe bus. Multiple safety sensors can be connected to asingle input and still achieve the highest level of safety. Plutohas inputs suited for every safety product on the market,and each input function is configured in the accompanyingsoftware Pluto Manager.Besides failsafe inputs (I) Pluto has a number of failsaferelay and transistor outputs (Q). On every Pluto unit thereis also a possibility of using a number of terminals asfailsafe inputs, non-failsafe outputs or both in and outputsimultaneously (IQ). The characteristics of the terminals areeasily configured in Pluto Manager.Safety in large and small systemsPluto models without bus communication are stand aloneunits and are therefore perfectly suited for smaller systemsthat do not require communication with other Pluto units orgateways. Pluto models with bus communication can beconnected to the Pluto bus where up to 32 Pluto units caninteract and control large as well as small safety systems.The fact that Pluto is an All-Master system means that eachPluto unit controls their outputs locally, while it is as easy toread other Pluto units' inputs as their own.Specifically for Pluto A20 is that it is equipped with ananalogue input for current measurement, which can beused for e.g. monitoring of muting lamps.Pluto is primarily designed to satisfy the requirements ofEU Machinery Directive (2006/42/EG) regarding safety incontrol systems, but the system can also be used in otherareas as in the process industry, boiler plants etc whichhave similar requirements.A Safety-PLC for eachsystem partDispersed constructions ofmachinesGreat flexibilityUp to 10 sensors in seriesconnected to one inputSoftware Pluto Manager freeof chargeHandles conventionalcircuit breakers as well asdynamical sensorsCustom made safety busFor product information and downloads please visitwww.abb.com/lowvoltageClick on Control Products, or search for our productsat www.abb.com/abblibrary/downloadcenter.2:6ABB
