2 Overview
General description
ABB/Jokab Safety adaptor units are used to adapt conventional safety sensors where the safety relies on e.g. one-
or two-channel static signals, OSSD outputs, or short circuit detection, to the dynamic safety circuit monitored by a
Vital safety module or Pluto safety-PLC.
Tina 2A and Tina 2B are used to adapt safety sensors with mechanical contacts to the dynamic safety circuit.
Examples of such safety sensors are emergency stops and switches or light curtains and light beams with internal
relay outputs.
Tina 2A is intended for safety sensors prepared with an M20 threaded connector. This allows easy installation of
the adaptor unit within the physical enclosure of the safety sensor while keeping the status LED visible on the
outside of the housing. Tina 2B has a very small form factor which allows installation inside the physical enclosure
of small safety sensors, or safety sensors without an M20 threaded connector.
The Tina2A/B adaptor unit is intended for use in safety circuits in accordance with EN 60204-1.
Warning!
In order to maintain the highest safety level and reduce the risk of electrical interference the unit must be
installed within the same physical encapsulation as the safety device. The connection cable should be as short as
possible (max 150 mm).
Safety regulations
