The 250Ω load resistor for 4-20mA range, the 100Ω load resistor for the 10-50 mA range, the Voltage divider for
0–10 Volts, or the 500 ohm C/J compensation resistor are supplied with the controller when the input is specified.
These items must be installed when you wire the controller before startup.
