Frequently asked questions
In this section we have answers to the most frequently asked questions. In case your question is not answered in this section please contact us by email email@example.com We have grouped the questions in the following sections:
How do I connect the A2007x?
The information about the connections can be found with our technical information page about 2 and 4 wire 4-20mA current loop
What is the difference between 2-wire en 4-wire current loop?
The difference is which device powers the loop. With 2-wire 4-20mA the power for the loop is delivered by the receiving equipment. With 4-wire 4-20 mA the power for the loop is delivered by the current sending equipment. The receiving equipment is passive.
What is the difference between active and passive 4-20mA?
Active 4-20mA equipment provides power for the loop. Passive 4-20mA equipment does not supply power to the loop. The A2007 is a passive 4-20mA device.
I want to test a I/P converter. How do I connect the A2007?
For testing a I/P converter or valve positioner an extra power supply is needed. A valve positioner is a passive 4-20mA device, the A2007 is also a passive 4-20mA device. The A2007 can be connected as indicated in the diagram below.
I want to test a Siemens SM331 analogue input module, can I use the A2007 current loop controller?
Yes you can, the SM331 analogue input module can be configured in both 2-wire and 4-wire 4-20mA. Depending on the configuration of the module, the A2007x can be connected as indicated in the diagram below.
The left diagram shows the SM331 module configured for 2-wire 4-20 mA (2DMU) the measurement range selection module is in position D. The card will supply power for the loop, the A2007 is passive.
The right diagram shows the SM331 module configured for 4-wire 4-20 mA (4DMU) the measurement range selection module is in position C. The card is passive, the voltage for the loop is supplied by the 24VDC power supply.
Can I use the A2007 current loop controller for simulating 0-20mA?
No, this is not possible. The A2007 current loop controllers are powered by the loop, a minimum current is necessary to power the A2007. The minimum current is 1,6mA see A2007E-SP
What is a 10 turn potentiometer?
On a 10 turn potentiometer the axle need to be turned 10 rounds for the complete 4-20mA range. A very accurate setting of the current is possible in this way. When the axle of a 10 turn potentiometer is turned 90 degrees, the current will change 0,4 mA. When the axle of a standard potentiometer is turned 90 degrees the current will change 4,8 mA
