These Safety Speed Monitors for incremental encoders / sensors are used to monitor ramp, under speed, overspeed, standstill and direction of rotation, with cable break monitoring of the sensor signals.
Safety Speed Monitors are used in applications where there is a high safety risk to people and machinery.
The DS series Safety Speed Monitors are specifically designed for these industrial applications.
•These safety speed monitors are used to monitor under frequencies, over frequencies, direction of rotation and machine standstill. •Safety functions equivalent to EN 61800-5-2 (SS1, SS2, SOS, SLS, SDl, SSM, SLI, SBC, STO, SMS) •1 incremental encoder input with format A, /A, B, /B, Z, /Z [HTL differential, RS422] •8 control inputs [HTL / PNP] •Input frequency up to 500 kHz •2 relay outputs 5... 250 VAC / VDC (NO) •4 x 2 control outputs with push-pull characteristic, short-circuit-proof, [HTL], univalent or equivalent redundant or simply used •Safety related 14 bit analog output for 4 ... 2 mA (scalable)
