Safety Speed Monitor for Incremental Encoders / Sensors

The speed monitor DS250 achieves SIL3/PLe with two non-certified sensors and includes two incremental inputs and line break monitoring.

• SIL3 and PLe certification
• Safety functions equivalent to EN 61800-5-2
• (SS1, SS2, SOS, SLS, SDl, SSM, SLI, SBC, STO, SMS)
• 2 incremental encoder inputs with format A, /A, B, /B, Z, /Z
• [HTL differencial, HTL single ended, 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], antivalent or equivalent redundant or simply used
• Safety related 14 bit analog output for 4 ... 20 mA (scalable)
• Signal splitter
• Power supply 18 ... 30 V
• Wire monitoring of the sensor signals
• Compact housing for 35 mm mounting top hat rail
• (according to EN 60715)
• USB interface for easy parameterization via user software
• BG200 operator panel for easy parameterization and display (optional)
