Up to 4 model servos can be controlled by the C-IS-0404S. module. Its outputs in the 50 Hz mode are used. Fig. 1 shows an example of connection of two servos, analogously the other 2 outputs are connected. Due to the power input of the motors, it is necessary to use an external power supply for the servomotors.
