Two-hand safety controls ensure protection against hand injury due to dangerous
machine movement. A two-hand safety control system is made up of two elements:
a control board and a safety control module. The control board has two control
devices that force the use of two-hand activation simultaneously. The safety control
element is a device like the FF-SR25980 two-hand safety module. This control mod-
ule relay is linked to the control board and is located in an enclosure.
APPLICATIONS
• Secondary protection for robotics,
presses
The module will accept input from the two control devices (between S13/S14 and
S23/S24) if Y1/Y2 are jumpered (or closed). When both input contacts close within
half a second and remain closed, the two normally open safety contacts (13/14 and
23/24) will close. If these input contacts fail to close within half a second, or if
power has been removed, another activation is required.
When one of the input contacts opens, the two normally open safety contacts of the
FF-SR25980 module will open immediately.
