Speed monitors

The speed monitors of the DZ series are designed for the installation in control cabinets. They are used to monitor overspeed, underspeed, direction of rotation or standstill of machines. Special models of the speed monitors, which have an analog output, can also be used for control tasks.

The special features of our speed monitors are the very high frequency range, the fast response and the easy adjustability of the speed, direction and standstill parameters depending on the used input signals.
 

Electronic monitor for monitoring left / right rotation and standstill. With universal pulse inputs for all common incremental encoders and sensors.

 

  • Pulse input with format A, B, 90° [HTL] or A, /A, B, /B [RS422],
    also possible for single channel
  • Input frequency up to 500 kHz
  • 2 output relays with potential-free change-over contact and
    2 transistor outputs with High-Side-Driver, short-circuit-proof, [7 ... 30 VDC]
Direction and Standstill Monitor

Compact device for monitoring overspeed, underspeed, standstill and direction of rotation with universal inputs for incremental encoders, proximity switches, light barriers or sensors.
 

  • Pulse input with format A, B, 90° [HTL] or A, /A, B, /B [RS422],
    also possible for single channel
  • Input frequency up to 1 MHz
  • 3 output relays
  • 14 Bit analog output for ±10 V or 0/4 ... 20 mA
Speed Monitor with 3 Output Relays and Analog Output

Performance as DZ260, but with 3 fast transistor switching outputs instead of relays.

Speed Monitor with 3 Transistor Outputs and Analog Output

Perfomances as DZ260, without analog output but with 3 transistor outputs.
