Adaptation unit
Tina 7A
Description
Tina 7A is a device that adapts the safety sensors with
mechanical positive forced disconnecting contacts, such as
emergency stops, switches and light curtains/light grids with
their own relay outputs to the dynamic safety circuit.
The device is designed for installation in an equipment
cabinet where it can be mounted directly on a 35 mm DIN
busbar, and the conductors are then connected directly to
the screw terminals.
