EMD-BL-C-10(-PT) Electronic monitoring relay for overcurrent and undercurrent monitoring of alternating current in single-phase networks Data sheet 105670_en_01 1 © PHOENIX CONTACT - 2016-05-03 Description Safety and system availability requirements 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 demands placed on energy technology are also constantly on the rise. It is only by continuously monitoring key network and system parameters that error-free and therefore cost-effective operation can be achieved. Electronic monitoring relays from the EMD series are available for a wide range of monitoring tasks so that the consequences of errors can be avoided or kept within limits. The operating states are signaled via color LEDs and any errors 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 delays so that measured values outside the set monitoring range can be briefly tolerated. Features – – – – – – Over/undercurrent monitoring Window function Adjustable threshold values Adjustable response delay Two adjustable monitoring ranges up to 5 A/10 A One PDT WARNING: Risk of electric shock Never carry out work when voltage is present.
