DS230: Certified Safety Monitor with Multifunctional Inputs for HTL-, RS422-, SinCos-Sensors and Signal Splitter

The DS230 is suitable for connecting incremental sensors with RS422 output (differential signals A, / A, B, / B), one-track HTL encoders and sine-cosine encoders. It is equipped with a relay, 4 transistor outputs, one analog output and one signal distributor. The DS236 is an alternative version without a signal splitter.

  • SIL3 and PLe certification
  • Safety functions equivalent to EN 61800-5-2
    (SS1, SS2, SOS, SLS, SDl, SSM, SLI, SBC, STO, SMS)
  • 2 encoder inputs with format SIN+, SIN-, COS+, COS- [1 Vss]
  • 2 pulse inputs with format A, /A, B, /B [RS422]
  • 2 pulse- or control inputs with format A, B, 90° [HTL / PNP]
    (for rotary encoder, proximity switches or commands)
  • Input frequency up to 500 kHz
  • Forced-guided redundant output relay (NO)
  • 4 control outputs with push-pull characteristic, short-circuit-proof,
    [HTL], each inverse and redundant
  • Safety related 14 bit analog output for 4 ... 20 mA (scalable)
  • With signal splitter
  • Power supply 18 ... 30 V
  • Compact housing for 35 mm mounting top hat rail
  • (according to EN 60715)
  • Setup via USB port by operator software or plug-in display and
    programming unit BG230 (accessories)
