Wire colors shown are typical but because there are exceptions, always refer to the color codes shown on the cable label or “
Control Cable Wiring”
table on page 11.
** Minimum resistor value is (100 x Vs) ohms. Higher resistances maybe used depending on frequency and cable length. Longer cables and high frequencies require
lower resistance.
***
Resistor RL converts 4-20mA current to voltage for voltage input only devices.
