Today we are going to show you how to use the PLC Tools SIM-ALP2 analog simulator to simulate a 4-20mA and 0-10VDC signal. The SIM-ALP2 can simulate a two wire current loop, a 4 wire current source, and a voltage source analog device. The full range in current mode is 0 to 22 milliamps so it can simulate broken wires and faulted sensors where transmitters output 21mA when the sensor attached to them is faulted. The full voltage range is -10VDC to +10VDC so it can simulate servo commands in motion control applications.
