Dual Channel Emergency Stop Module
IMPROPER INSTALLATION
• Consult with US and/or European safety agencies
and their requirements when designing a machine
control, interface and all control elements that
affect safety.
• Strictly adhere to all installation instructions.
Failure to comply with these instructions could
result in death or serious injury.
PRODUCT DESCRIPTION
The FF-SRS5988 Emergency Stop modules are
designed to be used in emergency stop circuits
when danger to personnel or machinery is present.
This device, offering six NO and one NC closed
contact, has two internal safety relays with positive-
guided contacts to ensure redundancy.
This
safety
control
emergency stop signal to the machine control
circuitry. FF-SRS5988 helps to create a control
reliable safety solution by providing redundancy and
self-checking circuitry. Other features include high
current capability, a great number of contacts as
well as an automatic or manual start mode, cross
fault monitoring, and external relays monitoring.
