How to Configure ABB Sentry Safety Relays


StatusBus from ABB Jokab Safety!

StatusBus is here: The newest revolutionary technology for machine safety solutions

StatusBus (a feature in every Pluto Safety PLC) allows you to connect the information output of your series safety devices (up to 30) into a single terminal and still be able to differentiate which device was activated.

StatusBus with Pluto allows for 30 devices to take only three safety inputs and only one StatusBus input.  This maintains Category 4, PLe, SIL 3 for the safety function as well as offers independent diagnostics for each device.

Most competitors need 90 inputs. We do it in with only four! That’s a 95 percent savings on I/O!

ABB – What you didn’t know about panel component inter-compatability

ABB newpanel-760px1The contents of an electrical control panel may seem complex, but when broken down into the different subsystems, it all starts to make sense. As you start to understand how the components, enclosure, and various hardware interact, you start to realize that it makes sense to select components designed with inter-operability in mind.

Read this article to learn why you should reconsider how you source panel components.

New ABB Contactors – Dedicated for Safety Applications

ABB Safety ContactorABB’s all-new range of AFS contactors for safety applications is now available to order. The launch of the new contactors completes the expansion of the company’s portfolio of safety components, making it possible to equip every aspect of a plant’s safety architecture with ABB technologies.

The new AFS contactors can be part of the safety chain in industrial machinery and process industry applications, stopping motors or triggering gas discharges. For machine safety applications, AFS contactors come with fixed front auxiliary contact blocks that make monitoring and controlling circuits easier. The mechanically linked and mirror contacts also help make systems safer.

Massimiliano Cifalitti, global product group manager for ABB’s motor starting and safety business, said: “The all-new AFS contactor shows why ABB is a leader in industrial safety. Its innovative design makes this key component for machine safety simpler to install, easier to maintain and safer to operate. With the most frequent updates to our complete range of safety components, and software tools to make workplaces safer by design, customers can choose with confidence knowing that ABB offers the best solution possible for their complete safety architecture.”

The all-new AFS contactors are designed to make integration into machine manufacturer systems easier. All the data for the contactors is readily available via safety design tools such as Sistema, or FSDT from ABB. For manufacturers, this makes it simpler to design machines with higher safety levels, complying with the main EN ISO 13849 and EN 62061 safety standards.

ABB’s ergonomic design makes operation safer and simpler. During routine maintenance, the distinctive yellow auxiliary contact block makes it faster and easier to identify the safety device in the panel, saving valuable time. A protective cover helps prevent accidental manual operation.

The range makes high-performance protection systems simpler to build. The power consumption of the contactor coil can be cut by up to 60 percent, enabling more compact transformers and panels. Built-in surge protection comes as standard. The device’s near-instantaneous response time improves safety. When a fault is detected, opening times are less than 30 ms for selected variants, enabling designs with significantly shorter safety distances.

Mechanically linked and mirror contacts are clearly marked with symbols on the front and provide the performance required in feedback circuits. This prevents any unexpected state changes of the auxiliary contact, should the main contacts become welded or stuck. It also ensures an accurate indication of the safety system status is displayed at all times.

“Safety designed contactors perform an essential function in machines, breaking the power supply to a load, usually a large electric motor,” said Cifalitti. “At ABB, we believe that better safety is always the right decision. Our teams of experts have designed the AFS contactor to reward that decision.”

Product Spotlight – Quick Guard Fencing from ABB/Jokab

quick-guard_fencing_system_1950x975_2-1Quick-Guard is a very flexible fencing system consisting of a minimum of different components, such as aluminum profiles, patented assembly parts, net-locks, mesh, solid or noise reduction panels.

Thanks to our patented screw-lock system, we can supply all brackets pre-mounted with fixing screws and nuts. No holes need to be drilled in the profiles and all cuts are made straight. Assembly and modification is therefore very easy.

Quick-Guard can be supplied to be designed by you on site (Quick-Guard Express) or designed and cut according to drawing (Quick-Guard standard).

When ordering a Quick-Guard fencing system, you give us a simple sketch or AutoCAD® file of how you want the fencing system to look. We put this information into our AutoCAD-based software SafeCAD and design the fence in 3D. From this drawing, cutting, component lists and a quotation are generated automatically.

Main benefits

  • Highly adaptable to various needs
  • Fast installation
  • Light weight
  • Esthetically appealing
  • Minimal maintenance needs
  • Complete system

Main features

  • Light and robust aluminum profiles
  • Large variety of materials for panels

Product Spotlight – “Magne” Robust Magnetic Process Lock

magne_1b_v2_magne_2b_v2_390x195Magne is an electromagnetic lock intended for electrical locking of doors and hatches with a holding force of up to 1500 N. Magne is usually used when access to the dangerous zone and the consequent stopping of the machine might only happen when specific conditions are met, at the end of the cycle for example.

Magne 1 and 3 are non-safe locks and must be associated to a safety interlocking device in safety applications.
Magne 2 integrates an Eden safety sensor and the interlocking function can reach up to a PLe/SIL 3.
Magne 1B, 2B & 3B have all an integrated permanent magnet which holds the door closed when no power is supplied.

Main benefits

  • Larger mounting tolerances than mechanical locks facilitates installation.
  • All the advantages of the integrated Eden safety sensor with Magne 2.
  • Extensive indication reduces downtime.
  • Less wear than a mechanical lock since there are no moving parts.

Main features

  • Less wear than mechanical lock
  • Holding force up to 1500 N
  • Up to PLe/SIL 3 with only one device
  • M12 connectors speed up installation
  • Possible to connect in series with Eden sensors and Tina units
