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 7A is 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. The

unit is also able to monitor short circuits and can therefore also adapt safety sensors with safety contact rails, or

safety mats with internal relay outputs, to the dynamic safety circuit.

Tina 7A is intended for use inside electrical cabinets where it can be mounted on 35 mm DIN rails and connection

cables can be connected directly to screw terminal blocks on the unit. Tina 7A is also equipped with a LED for

visual status information of the safety sensor and the dynamic safety circuit.

The Tina 7A 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 cables should be as short as

possible (max 150 mm).
