3.10.2 Remote Current Programming by Voltage Source
Two inputs are provided for remote voltage-programming of the output current:
5 VDC full-scale and 10 VDC full-scale. The DC voltage source is connected
between Pin J1-10 (IP 5 V) for 5 VDC source, or Pin J1-16 (IP 10 V) for
10 VDC source, and the return Pin J1-23 (IP RTN).
The corresponding voltage-programming coefficients for output current are
(100% rated output current) / 5 VDC, or (100% rated output current) /10 VDC,
from the respective inputs with return to Pin J1-23 (IP RTN). This produces
transfer functions for output current, as follows:
Iout = Vdc * (100% rated output current) / 5 VDC), with Vdc in volts, or
Iout = Vdc * (100% rated output current) / 10 VDC), with Vdc in volts.
Note: The return Pin J1-23 (IP RTN) must be referenced directly to, or within
±3 V, of the circuit common, Pins J1-6 and J1-24. See Figure 3-15 for
connection requirements.
