Function Description
The two-hand relay is a safety device
to ensure that operators keep their
hands away from the danger zone.
The relay is suitable for use with
mechanical and hydraulic presses, or
in safety circuits.
A cycle can only be initiated by
pressing the two pushbuttons
simultaneously (within 0.5 s). A cycle
is interrupted by releasing one or
both buttons to stop the output.
The output signal can only be
reinitiated after both inputs have
been released and the pushbuttons
are operated again.
