Dynamic signals in machine safety deliver cost savings

Jokab Safety has developed a system which allows the machine builder to enjoy the benefit of series-connecting multiple safety devices, while at the same time still meeting the highest safety requirement. This safety system, called the Vital Solution, consists of a control unit - the Vital 1 - which is the same size as a standard safety relay. This control device has two functions. One is to provide two safety outputs in the form of two, twin channel, volt-free contacts to switch the main power circuit when a safety device in the field has been activated. 

The second is to produce a coded signal from a monitoring circuit. This coded signal is transmitted to the first field safety device. It is received and inverted using a tiny interface, before being sent on to the second field device. Again, the signal is inverted, back to the original form sent from the Vital 1, and sent on to the third device. This transmission and inversion of the signal continues until the last device in the circuit, whereby the signal is received back into the Vital 1. 

The Vital 1 can support up to 30 field devices connected in series within a 500m cable run. The Vital system means that manufacturers can enjoy a cost-reducing, functional safety system without compromise of to the safety level. At component level, machine manufacturers can enjoy a saving of up to 30 percent. The added benefit of an increase in productivity during installation means the cost savings can go even higher.
