A single relay for all safety applications
Jokab Safety has, for several years, pioneered the universal relay concept, i.e. relays that are suitable for use with all types of safety device or, in other words, the 'one for all' concept. Its latest RT Series brings this 'one for all' concept to reality, with just three different models on offer to satisfy all machine safety requirements.
The RT6 is available in DC and AC versions, all of which are compatible with single and dual channel inputs from the safety device. They have monitored and automatic reset options, as well as test inputs available. To complement this, they have three normally open safety outputs, plus two non-safe transistor outputs for information purposes.
The RT7 offers the same as the RT6, but has instead four normally open safety outputs, two of which are configurable as delayed outputs for 'soft' stop requirements. Finally, the RT9 is a DC-only model offering two normally open safety outputs in a unit measuring just 22.5mm wide. When ordering, you simply state RT6/7/9 and, in the case of the RT6 and RT7, the required voltage option (one DC and four AC options available). Spares are considerably reduced to maybe one or two units to cover all machine safety requirements and breakdowns. Hence, costs are reduced and the likelihood of having the wrong relay becomes a thing of the past.
All RT models offer up to full Safety Category 4 protection and are backed by a range of safety timers and expansion relays for those more demanding safety applications.
