Vital allows connection of 30 field-safety devices
A
Jokab Safety UK product story
Edited by the Engineeringtalk editorial team
Mar 18, 2009
Jokab Safety is using the Vital coded pulse system, which can operate all components from all manufacturers in the safety-related market.
This system allows up to 30 field-safety devices to be connected in series and connected to a single control unit without compromising the safety level.
Doing this with conventional systems would only allow the user to meet category 3 / Sil level 2.
Jokab Safety's method meets category 4 / Sil level 3.
The advantage of this is that the engineer does not have to change his field devices should they already be installed or part of a specification from the client.
The major benefits include reduced cost and eliminating the possibility of having to locate a single channel fault on the safety system.
