Pulse Output Application - Sourcing Mode (Recommended for Rin < 30kΩ)

Pulse Output Application - Sinking Mode (Recommended for Rin > 30kΩ)

Analog (4-20mA Current Loop) Output Application

** 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.
