Vital 3 is a safety controller that combines functionality with the quick and easy

installation of safety sensors. With two safe input functions and two different output

groups, Vital 3 offers the capability to exclusively control smaller machine safety sys-

tems that would otherwise have required a programmable controller or multiple safety

relays. How the two output groups are controlled by the input functions depends on

which of the three operating modes is selected (see Selection of operating mode).

Input function 1

A two-channel safety circuit designed for opening contacts, e.g. two-channel emer-

gency stop or ABB JokabSafety's safety switch JSNY5. One channel is fed with the

dynamic signal and the other with static +24 VDC.

Input function 2

A dynamic safety circuit where ABB JokabSafety's safety sensors Eden, Tina and

Spot can easily be connected in series. Up to 12 Eden or Tina devices can be con-

nected in series per input function.

Output group 1

A safe relay output in a duplicated series and a safe transistor output with output

voltage of -24 VDC.

Output group 2

A safe relay output in a duplicated series and a safe transistor output with output

voltage of -24 VDC. In addition, output group 2 contains a non-safe transistor output

with output voltage of +24 VDC, intended for information. The output group can have

time delay from 0 to 1.5 s.

Selection of operating modes

Vital 3 can be conﬁgured to operate in one of three operating modes M1, M2 or M3.

The selection of operating modes is done by connecting one of the terminals M1, M2

or M3 to +24 V.
