Standards current loop test devices
In order to ensure the compatibility of the current loop test units to other equipment these units conform to several internationla standards.
The A2007 series 4-20 current loop testers comply to the following standards:IEC 60381-1 Analogue signals for process control systems. Part 1: Direct current signals. ISA-50.1-1982 (R1992) Compatibility of Analog Signals for Electronic Industrial Process Instruments Namur NE 006 Standardised Electrical Signals and Questions relating to Engineering Technology
These standards specify the voltage and current levels for the current loop, the load of the circuit is specified as well.
Like all electronic equipment the DIVIZE current loop test units need to comply with electromagnetic compatibility standards. The tests are conducted according the folowing standards.NEN-EN-IEC 61326-1:2006/C1:2008 Electrical equipment for measurement, control and laboratory use – EMC requirements – Part 1 General requirements. Namur NE21 Electromagnetic Compatibility of Industrial Process and Laboratory Equipment.
The IEC 61326 and Namur NE 21 standard are mainly equivalent. In cases there are differences between the standards, the highest test levels are used. The Namur NE21 describes additional test regarding voltage dips and fluctuations.
The DIVIZE current loop testers are tested according the following additional standards:NEN-EN-IEC 61131-2:2007 Programmable controllers – Part 2: Equipment requirements and tests NEN-EN-IEC 61800:2005/A1:2012 Adjustable speed electrical power drive systems - Part 3: EMC requirements and specific test methods
The current loop test units are frequently used in combination with PLC and DCS systems. Although it is not required by the CE DIVIZE has tested the current loop units according to these standards as far as applicable. The use of the current llop test units for setting speed, torque and other parameters on frequency converters and drive systems is also a common application. Therefore the units are evaluated according these standards as well (as far as applicable).
