4 20mA current loop tester with indicator and 4mm connection

Excl. VAT

4-20 mA current loop tester with indicator and 4 mm laboratory connections.

De A2007B-4M signal-source is designed as a universal 4-20mA tester. The A2007B-4M is an essential tool for the instrumentation technician and shall be present in every instrumentation workshop. The A2007B-4M can be used for testing PLC analog inputs, displays and barriers. When an external power source is used, the A2007B-4M can also be used as a signal source for I/P converters, valve positioners etc.

The multi-turn potentiometer allows a precise and exact setting of the current. The indicator gives a direct indication of the status of the loop, is it powered and working as intended.


  • Multi turn potentiometer for accurate and stable current regulation.
  • Simple connection with 4 mm laboratory connections.
  • Loop-powered suitable for 2-wire and 4-wire current loop.
  • Over-current protection.
  • Protection for wrong connections.
  • Stable current setting by internal current regulation, no temperature influence.
  • Standard current range.

The A2007B-4M 4-20mA signal-source is not equipped with a battery, it is a passive 4-20mA device.

More information about the connection of the 4-20mA current loop tester can be found in our technical information section.

The A2007B-4M has two 4mm laboratory connections. These can be used to directly connect test wires with 4 mm banana plugs. The connections can also be used to fasten wires. These connections make it possible to hook up the A2007B-4M in any situation. Optional is a set of test wires available.

The A2007B-4M is used by engineers and mechanics in production, chemical, paper and automation industries.

The A2007 series of current loop simulators is designed an tested according European and international standards. The CE declaration of conformity can be downloaded from this page. More information about the applicable standards can be found on our technical information page about international standards
