The system supports numerous input devices such as E-stops, light
curtains, enabling switches and interlock switches, which detect
demands on the safety system and initiate a stop request of the motion.
It also monitors personnel in the hazardous area while the machine is
in a safe-speed condition. Users can configure the safety relay with
either Allen-Bradley DriveExplorer software or a human interface
module. The relay can be used with standard drives and with the
“safe-off” option on Allen-Bradley PowerFlex drives. It monitors the
speed of the motion via one or two encoders, depending on the level of
integrity required.
