2. Introduction
This series of speed monitors is suitable for safety-related monitor tasks e. g. over-speed, under-
speed, standstill and direction of rotation. This SIL3/PLe certified generation of devices was
developed to achieve functional safety by supporting a wide range of sensors and encoders in
different combinations.
Due to its innovative multifunctional inputs these devices are perfectly suitable for the retrofitting of
existing plants and machines which are using “non-safe“ sensors. This offers a great opportunity to
save costs for expensive and certified sensors. Also the costs for new installations and adjustments
can be reduced significantly by using the existing components and wiring.
Typical examples are centrifuges, cranes, wind power or hauling plants.
Special features:

Additionally suitable for a "Set-Up Operation",
e. g. for manual settings at plants with open doors and reduced speed

All models are safety-related and dually certified according to
EN 61508, EN 62061 / SIL3 and EN ISO 13849-1 Cat. 3 / Ple,
even when using “non-safety-related” standard sensors or encoders

Wide input frequency range and fast response time

Very versatile range of possible monitoring functions

Easy setup by PC via USB or by the optional programming module BG230
