It sits between the DP/PA coupler and the field instruments, providing diagnostics, spur line status, and automatic bus termination. ## Temperature range and power budget Rated for ambient operation from -40 °C to 85 °C, so it can live in freezers or hot enclosures without derating. Power consumption maxes at 4.1 W (typ. 544 mW), and the coupler draws up to 514 mA from the loop or auxiliary supply. Each PA spur line is limited to 60 mA; the coupler supports eight devices, so total spur current must stay under 480 mA. Reverse polarity protection is built in, but only when paired with the FDC 157 power conditioner. ## Field mounting and wiring Enclosure dimensions: 360 x 120 x 83 mm (width x height without screw glands x depth). IP66 keeps it clean for wash-down or outdoor locations. Automatic bus termination on the main line means no jumper or resistor to install — the coupler handles it internally. PROFIBUS PA main cable must be Type A; spur lines also Type A. The coupler includes a status indicator and diagnostics function, plus main line failure reporting.","metaTitle":"Siemens 6ES7157-0AG82-0XA0 PROFIBUS PA Coupler, IP66","metaDescription":"Siemens 6ES7157-0AG82-0XA0 PROFIBUS PA Segment Coupler.
