Loop isolator by JM Concept offers quick response time, more

The JK 0030A1 powered loop transmitter

JM Concept solutions are available in Canada from Durham Instruments, including the manufacturer’s selection of loop isolators. For example, the JK 0030A1 powered loop transmitter has been designed specifically to isolate 0…4…20mA, and it is built with a guarantee to last for at least five years of reliable performance.

The JK 0030A1 is a loop isolator measuring 22½ by 81 by 98 millimetres (mm), with a universal power supply, sensor power supply, and hot-swappable plug for plugging in and out.

Three possible input/output settings

This powered loop transmitter is a versatile device that works for applications in a wide variety of industries. Durham Instruments recommends it for use in general manufacturing, aerospace, automation, food processing, pharmaceuticals, forestry, education, the medical field, the military, mining, packaging, power generation, alternative energy, transportation, and research and development.

The device comes in a 22½-mm case, and customers who want BASELINE boards can order them separately – or contact the distributor for multi-converter boards. The JK 0030A1 comes with three possible input/output settings: 0-20mA/0-20mA; 4-20mA/0-20mA; or 4-20mA/4-20mA. For input gauges, users can use a current (continuous) option at 0-20mA or 4-20mA or a two- or three-wire sensor supply at 24 volts to a maximum of 29mA. The output gauge has a current of 0-20mA or 4-20mA. Other specifications of this product:

• Input maximum current: 200mA
• Current input impedance: 4¾ ohms
• Permissible impedance on the current output: less than 800 ohms
• Supply/input-output isolation: 4,200Vrms, 50 hertz, one millinewton
• Input/output isolation: 1,500Vrms, 50 hertz, one millinewton
• Auxiliary-source voltage supply: 22-240Vdc or 90-230Vac, 50/60 hertz
• Precision class: 0.1
• Response time: less than 100 microseconds
• Thermal drift: less than 50 parts per million
• Residual ripple on current output: less than 150 microamperes
• Maximum consumption: less than 5½ volt-amperes
• Operating temperature: from minus ten to 60 degrees Celsius
• Storage temperature: from -25 to 80 degrees Celsius
• Protection factor: IP20 Black self-extinguishing polyimide housing V0
• Options: tropicalization in a 22½-mm case; auxiliary source of 20-60Vac; and lightning shock resistance.

There is a six-step output-setting procedure that begins with connecting a current generator to the input terminals.
