4-20mA Joystick Buffer Board
Product Description: Electronic buffer board with 4-20mA current output.
This device is designed to regulate the power supply to the buffer any Penny and Giles joystick. It has a regulated 5V supply to the joystick, has an additional 2.5V reference voltage for center tap stabilization. Its 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. The device is provided with a 16 Way harness which allows easy interconnection between the byffer board, joystick and the rest of the system.
