250-ohm Resistors for 4-20 mA Inputs
Except for the “G” Option Board, every PCC-IV Analog Input channel has an internal 250.0-ohm precision resistor
that the user can connect to the input. If connected, the 250-ohm resistor converts a 4-20 mA signal into a 1-5 Vdc
signal.
The
“G” Option Board is used primarily to drive electric actuators with 0-5 Vdc position feedback potentiometers. If
“G” board analog inputs will be connected to a 4-20mA signal, externally mounted 250-ohm resistors are required.
Precision 250.0-ohm resistors are available separately as part number 25250-0B25-3/4.
CPU Board JP1 jumpers:
Install a jumper to connect the
internal 250.0-ohm resistor for the
applicable analog input channel.
