Motor reversing relay, Micro drives are increasingly being used in building automation. Such very compact drive systems usually work with DC motors and therefore cannot be operated with conventional controls designed for AC motors. The MUR U1 takes over the necessary conversion from AC control to DC drive., A reversing logic is used to reverse the direction of travel, and an adjustable cut-off current in conjunction with the adjustable response time ensures a precisely adjustable and safe limit switch-off., Dimensions: 43x43x33mm, 12V DC, 10mA-2A'
