1description electronic monitoring rela y for temperature monitoring emd-bl-ptc(-pt) ? phoenix contact - 2016-05-10 data sheet safety and system availability re quirements are constantly on the increase ? across all industries. processes are becoming more and more complex, not only in machine building and the chemical industry but also in building technology. the de- mands placed on energy techno logy are also constantly on the rise. it is only by continuously mo nitoring key network and system parameters that erro r-free and therefore co st-effective opera- tion can be achieved. electronic monitoring relays from the emd series are available for a wide range of monitoring tasks so that the consequenc es of errors can be avoided or kept wi- thin limits. the operating states are signaled via colo r leds and any er- rors that occur can be sent to a controller via a floating contact or can shut down a section of the system. all device versions are equipped with response dela ys so that measured values outside the set monitoring range can be briefly tolerated. warning: risk of electric shock never carry out work when voltage is present. make sure you always use the latest documentation. it can be downloaded from the product at phoenixcontact.net/products. ? winding temperature monitoring 107385_en_00 features
