In many applications it is a requirement that the Dart product being used be interfaced with a supervisory control - plc/micro-controller/computer/HMI. Most applications involve a traditional analog signal sent to the control to set motor speed, and turn the control on or off. More and more we are seeing the need for serial interface over a network-Dart has responded with our Modbus serial interface for the 150 Series. The following details follower/interface options Dart offers and which controls they may be used with in the Analog SCR Drive group.
N/AThis is an optically isolated 4-20mA signal follower. It installs on the speed pot terminals of the control.The -5 is a pure signal follower that takes the place of the traditional manual speed pot. The -7 is similar but adds the ability to either control with a local speed pot in Manula mode. For models 123D, 125D, 251G, 253G, 130, 132 and 530B.
