1. Introduction
This new series of monitors has been designed as control modules for mounting inside of
electric control cabinets. The units are suitable for speed monitoring of machines, signaling
overspeed, underspeed, zero motion and the direction of rotation. Units providing an analogue
output can moreover be used for closed-loop control or feedback purpose within a control
system.
Very special advantages of these new monitors are the wide frequency range, the extremely
fast response and the remarkable versatility with regard to possible programmable monitoring
functions.
2. Available Models
There are five models available, all with fully similar basic functions, but with different options
concerning the outputs.
DZ = Function: Speed Monitor
