PR 6185 Loop-Powered Isolator

The PR 6185 Loop-Powered Isolator is a versatile industrial signal isolation module that provides galvanic isolation for analog 4-20 mA current loops without the need for an external power supply. Ideal for process automation and control systems, this compact loop-powered isolator supports 1-, 2-, or 4-channel configurations. Furthermore, the 6185, from PR electronics, delivers reliable, noise-suppressed signal transmission for SCADA, PLC, and DCS installations.

• Galvanic separation of analog current signals.
• Elimination of ground loops and measurement of floating signals.
• A competitive choice in terms of both price and technology for galvanic isolation of current signals to SCADA systems or PLC equipment.
• Especially useful in applications necessitating an unproblematic transmission of current signals according to NAMUR (sensor error detection).

PR 6185 Loop-Powered Isolator from PR electronics

By eliminating ground loops and isolating floating signals, the PR 6185 Loop-Powered Isolator enhances measurement accuracy and protects sensitive equipment from electrical interference and potential loop errors. It is especially suitable for applications requiring uninterrupted transmission of current signals in accordance with NAMUR sensor error detection standards. Thus, the 6185 is an ideal choice for demanding industrial environments. The isolator is powered directly by the measured current signal, drawing a maximum of 1.8 V from the loop, and also features built-in overvoltage and polarity protection to enhance durability. Low response time and high noise suppression ensure dependable performance even in electrically noisy settings.

• The PR 6185 loop-powered isolator is powered by the measured signal and loads the loop with maximum 1.8 VDC. 
• The input features protection against overvoltage and polarity error.
• The drop voltage for each channel can be calculated according to the following expression: Vdrop = 1.8 + Iout. * Rload.
• The output is voltage-limited to 15 VDC.
• Inputs and outputs are floating and galvanically separate.

Easy Mounting, Installation, and Programming

Suitable for easy DIN-rail mounting, multiple PR 6185 units can install side-by-side without spacing, thus allowing up to 168 channels per meter. With floating and galvanically separate inputs and outputs, this loop-powered isolator delivers efficient signal integrity, improves process reliability, and simplifies installation for industrial control systems.

• Mounts vertically or horizontally on a DIN rail.
• As the devices can mount without distance between neighboring units, up to 168 channels can mount per meter.
