INTERFACE Monitoring - Monitoring modules, time components and function blocks
Requirements pertaining to safety and system availability increase constantly – regardless of the sector. Processes are becoming more and more complex, not only in the mechanical engineering and chemical industry but also in plant and automation technology. Demands on power engineering are also constantly on the rise. Trouble-free and therefore cost effective operation can be achieved only with continuous monitoring of significant network and system parameters. Electronic monitoring relays of the EMD series are available for the widest variety of monitoring tasks to avoid the consequences of errors or to keep them within limits. The product family is supplemented with the time relays of the ETD series to control the time sequences in production and process engineering. The operating states are signaled using colored LEDs and the errors that may occur can be sent to a controller through a potential-free contact or can shut down a section of the system. Some device versions are equipped with startup and response delays in order to briefly tolerate measured values outside the fixed monitoring range.
Monitoring relay
The monitoring modules of the EMD series offer a cost-effective solution for the monitoring
tasks such as current, voltage, phase parameters, coil temperature, motor load and fluid level.
Timer relay
A practical combination of functions and time setting ranges as well as devices with special
functions (star-delta) are available for the timer relays of the ETD series.
Function blocks
In the function blocks, simple functions down to the component level are packaged for
industrial use and provided with professional connection methods. Examples: Diode
modules, lamp testing modules, display modules, motor attenuation modules.
