Speed and Motion Monitors

Product Description

SIL3/PLe certified Safety Monitor for Speed, Standstill and Direction of rotation
(for connection of a SIL3/PLe certified SinCos encoder or sensor)

DS 240*: (1 relay, 4 control outputs push-pull, analogue output, signal splitter)
DS 246*: (1 relay, 4 control outputs push-pull, analogue output)
BG 230*: Display- and programming module (optional)

  • SIL3 and PLe certification

  • Safety functions equivalent to EN61800-5-2 (SS1, SS2, SOS, SLS, SDI, SSM)

  • Suitable for the connection with SIL3/PLe certificated Sine-Cosine sensors or

    SinCos encoders with 1 Vpp (format sin+, sin-, cos+, cos-)

  • Two inverse redundant HTL / PNP inputs for encoders, proximity switches and control commands (10 – 30V)

  • Extremely large bandwidth of 500 kHz

  • Forced guided redundant output relay (NO). Beside device errors, more alarm states can freely be parameterized (over- and under-speed, direction of rotation, standstill)

  • The function of the four inverse redundant digital outputs is also free programmable

  • Safe analogue output with 4 – 20 mA for transmitting of proportional control loop values

  • Easy and safe integration into existing sensor wirings enabled by the integrated signal splitter

  • Fast and intuitive parameter setup by using the free service software or by using the programming module (optional)

  • Snap-on module for standard DIN rails (35 mm C-profile)

SIL3 Speed and Standstill Monitor

 ______________________________________________________________________

SIL3/PLe certified Safety Monitor for Speed, Standstill and Direction of rotation equipped
with multi functional inputs
(redundancy due to free combinations of  SinCos-, Incremental- and HTL- encoders or sensors)

DS 230*: (1 relay, 4 control outputs push-pull, analogue output, signal splitter)
DS 236*: (1 relay, 4 control outputs push-pull, analogue output)
BG 230*: Display- and programming module (optional)

  • The model range DS230 – DS236 is equivalent in function to the devices DS240 – DS246 (described above), except of the sensor inputs

  • Furthermore these types are suitable for the connection of incremental encoders or sensors with RS422 output (differential signals A, /A, B, /B)

  • Free combinable with Sine-Cosine sensors or SinCos encoders with 1 Vpp (format sin+, sin-, cos+, cos-)

  • Redundancy can also be achieved by HTL encoders or proximity switches

    anti-clockwise rotation and standstill

  • Versatile impulse inputs for operation with all common incremental encoders and sensors

ZD 640: Industrial Controller and Monitor for
Slip, Skew Position, Torsion, Shaft Fracture

[PDF manual]

  • Industrial Monitor with inputs for two independent incremental encoders, each A/B (2×90°) or A, /A, B, /B (RS422 or TTL)

  • The unit forms the difference between both encoder positions and compares the result (including sign) with four programmable preset values

  • Four output relays indicate the state of the actual position error

  • Selectable Reset functions under timer control also allow monitoring of nominal slip, with alarm outputs when exceeding slip preset limitsPrinciple of Slip Monitoring

    Example: Monitoring of shaft torsion and gear backlash

MS 640: Universal Motion Monitor for Safe and Redundant Monitoring of Motion
(speed, position, direction, motion aberration etc.)

[PDF manual]

  • Programmable monitor, designed for monitoring and controlling of admissible and impermissible operating conditions on machinery systems.

  • This unit is not just a speed monitor, but provides comparison between peripheral motion, motor motion and scheduled demand values of the control system.

  • 2 separate encoder inputs, 4 control inputs and 6 logical inputs for pick-up of motion and peripheral events

  • Continuous measuring and evaluation of all actual values of both encoders (actual speed, direction of rotation, motion or standstill, actual position, differential position)

  • 4 fast switching transistor outputs and 4 forced-guided relay outputs, all with  safety monitoring by internal feedback

  • Easy PC setup of the the desired monitoring functions and the output switching conditions

  • Extensive peripheral safety by detection of external problems

    (mechanical, sensors, cables etc.)

  • High functional safety by extensive self tests for detection of internal failures,  breakdown of components, malfunction etc,
