DZ 210: Simple Monitor for Standstill and Direction of Rotation
|
|
- Simple monitor for control of clockwise or
anti-clockwise rotation and standstill
- Versatile impulse inputs for operation with all common
incremental encoders and sensors
- High maximum input frequency (500 kHz) and very fast
response time (<1 msec. with f >1 kHz)
- Two output relays (dry change-over) and
two fast-responding transistor outputs

DZ 260, 266, 267: Versatile Speed / Standstill / Direction Monitors
|
|
DZ 260: Monitor with 3 output relays and analogue output
DZ 266: f / V converter with analogue output only (no relays)
DZ 267: Monitor with 3 output relays (no analogue output)
- Very versatile and fast-responding units for control and monitoring of overspeed, underspeed (with start-up delay), standstill
and direction of rotation
- Impulse inputs for use with single channel-signals (A only) or
quadrature signals (A, B, 2x90°) or TTL- and RS422-signals
with differential format A, /A, B, /B
- Wide operating range from 0.1 Hz to 1 MHz
- Parameter settings by 4 front keys and LCD menu
- Serial RS232 interface
- Power supply 24 Vdc
- Auxiliary +5V output for supply of TTL encoders
- Housing for panel or DIN rail mounting

ZD 640: Monitor for Slip, Skew Position, Torsion, Shaft Fracture
|
|
- Monitor with inputs for two independent incremental encoders, each A/B (2x90°) 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 limits
Example: Monitoring of shaft torsion and gearbox backlash

MM 640: Universal Motion Monitor
for Safe and Redundant Monitoring of Motion Sequences
|
|
|
|
- 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 relay outputs to signal OK or alarm states
- Easy PC setup of the the desired monitoring functions and the output switching conditions
