terminal.
Remote control input for current programming using a
voltage source connected between this pin and signal
return.
Signal return: Pin 18, Circuit is electrically connected to
the output power negative terminal
Range: 0 V to user selectable maximum range (2 V to 10
V) for 0 to full scale rated Output

Input impedance: 20 kΩ, typical
INPUT
Note: Do not exceed an input of 25 VDC
This remote-control input can be configured to take 4- 20
mA current input for current programming. Uses same
signal return pin 18 for 4- 20 mA input type also.
Fixed range from 4 mA to 20 mA for 0 to full scale rated

Input impedance: 500 Ω, typical
Remote control input for current programming using a
resistance connected between this pin and signal return.
Current Source of 1 mA is connected to this pin from the
power supply to enable resistance programming.
