Model ELMS1

Intelligent safety electronic

safety system

The ELMS system is a multifunctional, modular upgradeable, configurable safety system. The electronic is used for danger prevention on hoists. It protects both the operator and the equipment itself. The system consists of a central module on which modules can be attached to add more functions.

The modules are connected by a redundant standart top hat rail bus. The electronic includes a wide range of safety digital and analogue inputs, secure semiconductor- as well as contact outputs. The status of the in- and outputs, supply voltage and other diagnostic tasks is displayed on a LED matrix.
