SIMATIC S7-400Siemens 6ES7972-0AC80-0XA0 SIMATIC DP RS 485-IS Coupler PROFIBUS to RS485-IS PLC Accessory
SIMATIC DP RS485-IS coupler links PROFIBUS DP to intrinsically safe RS485-IS field devices, IP20, Zone 2.
Description
About the 6ES7972-0AC80-0XA0
About the 6ES7972-0AC80-0XA0
The Siemens 6ES7972-0AC80-0XA0 is a SIMATIC DP RS 485-IS coupler that bridges a standard PROFIBUS DP segment to an intrinsically safe RS485-IS segment, letting a DP master reach IS-rated field devices installed in a hazardous Zone 2 area. It runs from a 20.4-28.8 VDC supply, draws up to 150 mA, dissipates 3 W typical, and carries an IP20 enclosure for panel or field mounting.
Selection Notes
Because the RS485-IS side is intrinsically safe, this coupler is the interface point that lets a standard PROFIBUS DP master reach transmitters and positioners mounted inside a classified Zone 2 area without wiring IS barriers to every device individually. The 20.4-28.8 VDC input and 150 mA draw size it for a 24 V control-cabinet supply alongside other DP station electronics. Confirm the downstream IS segment length and device count stay within the RS485-IS power budget before adding this coupler to an existing DP trunk.
Applications
Used on PROFIBUS DP segments that must reach intrinsically safe field devices in hazardous Zone 2 areas, such as process instrumentation sharing a cabinet with standard, non-IS DP stations.
