Simulating a Current 2 Wire 4-20mA signal with the PLC Tools SIM-ALP2

Simulating a 4-20mA current loop should be the simplest connection since it only requires "2 wires" but we get more questions about this type of connection than any other analog configuration.  In this video we show you how to use the PLC Tools SIM-ALP2 to simulate a basic 2 wire analog device.
