Synchronizing Card

Synchronizing card is a device used to synchronize the speed of all the VFD equally according to master input. There are 8 output channel having potentiometer and VFD connected potentiometer is used to adjust the speed up to the upper limit of master input. For e.g. if the upper limit of master input is 10V then all the output will vary in range of 0-10V, if the master input is 7V then all the output will vary from 0-7

8 Channel 24V Relay Card

This relay board provides a convenient way to add relays to your system by allowing the connections to the coils and contacts to be wired with screw terminals. No soldering is required. This board includes 8 SPDT relays with convenient screw terminal connections and includes LED's which indicate when each relay coil is energized. In addition, a protection diode is installed across the coil of each relay in order to suppress the inductive spikes which occur when relay coils are de-energized. The relay contacts are electrically isolated from the rest of the board, which allows the load circuits to be electrically isolated from the control circuits. Relays allow high-current loads to be switched with a low-current control signal. The control signal energizes an electromagnetic coil which mechanically closes a set of electrical contacts. The contacts are electrically isolated from the coil, allowing a low-voltage, low-current control signal to control a high-voltage, high-current load. These relays can be used to switch both AC and DC loads in a variety of applications.
