Harmony Relay. Modular semiconductor relay for mounting on a top hat rail in an innovative, compact design with a cooling surface on the side. The load circuit is designed for 1-pole direct current networks in the range of 1-100 VDC and 6 A can be switched. The switching behavior is direct current switching and corresponds to a normally open contact. The control voltage is 4-32 VDC. An LED display provides information about the control. The connection is made using screw terminals. The dimensions are 11x88x84 mm.
