PLC Tools SIM-ALP Analog Simulator User Manual
The Loop Simulator Professional was developed to assist maintenance personnel and integrators in analog input testing,
troubleshooting and application development.
This 3-in-1 device simulates a 2-wire loop powered transmitter, provides 4 - 20mA current source and 2 - 10V voltage source.
A specific output selection made by three selector switches:
“Mode” (top) switch selects one of three available modes
Two “Range” switches select one of five preset current or voltage outputs.
Warning: Selecting Current Source or Voltage Mode with an externally powered loop will damage simulator.
In Current 2-Wire and Source Modes five pre-set output settings are available:
4mA, 8mA, 12mA, 16mA and 20mA under wide range of loads from 0 to 500 Ohm.
Voltage Mode has five preset values: 2V, 4V, 6V, 8V and 10V. In Voltage Mode load impedance below 20kOhm will cause lover than expected voltage readings.
A typical Current 2-Wire installation requires a loop power supply usually provided by an external 24VDC power supply.
Some sourcing Analog Input modules can provide loop power also.
Follow the Analog Input Module specification for a power supply selection
In Current Source and Voltage Mode Loop Simulator will provide the loop power and voltage signal source using
internal boost converter powered by two AA Ni-MH rechargeable batteries.
Alkaline batteries can be used as an emergency source only.
When not in use keep device in Current 2- Wire Mode to save batteries.
Important: Do not use this device for an input module or instrument calibration. This device is a simple testerthat provides current or voltage signal within a selected range.

This device is intended to provide general assistance with current loop debugging, testing and application development.
It should not be permanently used in live production systems.
Accordingly, production system must be tested and commissioned with real instruments to ensure safe and reliable operation.
