The FF-SRS5925 Emergency Stop modules are designed to be used in emergency
stop circuits when danger to personnel or machinery is present. This slim housing
device has two safety relays with positive-guided contacts to ensure redundancy.
In the manual start mode, the module accepts input from the safety device (light
curtain, safety mat, safety switches, etc) between S11/S12 and S21/S22 after acti-
vation of the push-button between S33 and S34; then, the normally open safety
contacts (13/14, 23/24) will close and the normally closed contact (31/32) will
open.
In the automatic start mode, the module accepts immediate input from the safety
device (light curtain, mat, safety switches, etc) between S11/S12 and S21/S22; if
S33/S34 are jumpered, the normally open safety contacts (13/14, 23/24) will close
and the normally closed contact (31/32) will open.
• Slim housing 22,5 mm / 0.89 in width
In either mode, if the safety device is actuated (emergency stop condition occurs),
the normally open contact will open immediately and the normally closed contact
will close. This emergency stop condition is relayed via the safety contacts of the
module to the machine control circuitry to arrest dangerous motion and/or remove
power.
APPLICATIONS
• Emergency-stop circuits on machines
• Door protection
• Conveyors/transfer lines
• Use with Type 3 or Type 4 Electro-
sensitive Protective Equipment for:
Cross fault monitoring must be used when two independent safety inputs are pro-
vided to this module to increase the overall safety level of the solution (see typical
application examples).
- Point-of operation protection
- Perimeter/zone guarding protection
