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-phase networks in the range of 48-600 VAC and 12 A can be switched. The switching behavior is instantaneous 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 with screw terminals. The dimensions are 18x88x84 mm.
