Description
● 22.5 mm S 99 housing,
DIN-Rail mounting
● Positive-guided relay outputs:
– 3 safety contacts (N/O)
– 1 auxiliary contact (N/C)
● Increase in the number of safety
contacts available by connecting
expander modules
● LED indicators for switching
status, channel 1/2 and supply
voltage
Function description
The two-hand control relay is used to
ensure that operators keep their
hands clear of the danger zone, and
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. 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
operated again.

● Increase in safety contacts
The number of output contacts can
be increased by using expander
modules or relays/contactors with
positive-guided outputs.
