The CDIM Electronic Interface Module is designed to work with any Penny and Giles, proportional output, potentiometer joystick. The CDIM is designed to buffer the output signal of the joystick. It has a regulated 5V supply to the joystick, has an additional 2.5V reference voltage for centre tap stabilisation. It’s wiper current draw will be in a magnitude of nano-amps offering very high input impedance. The device has over current polarity and over voltage protection. Each Control Devices module can handle 2 analogue joystick channels. The device also provides over current protection for the directional track switches for the joystick.
