Siemens Expansion module Profibus DP, plug-in Part number 7KM9300-0AB01-0AA0

Product Overview

The Siemens 7KM9300-0AB01-0AA0 is a plug-in expansion module (communication module) — a PROFIBUS DP interface — intended for use with compatible SENTRON/7KM PAC energy-metering / power-monitoring devices such as PAC3200, PAC4200, and 3VA COM100/800 series. It adds field-bus communication capability, allowing the meter or monitoring device to be integrated into a PROFIBUS DP network for automated data exchange, monitoring, and control in industrial or power-distribution systems. Its compact design and plug-in mounting make it a convenient add-on to expand existing installations without requiring a full replacement of the base device.

Key Features

• PROFIBUS DP expansion module — enables PROFIBUS DP communication for compatible PAC/monitoring devices
• Plug-in module — easy to attach to supported base devices (PAC3200 / PAC4200 / 3VA COM100 / COM800)
• Galvanic isolation — provides insulation up to 500 V AC for safe network integration
• Rated for industrial environment: pollution degree 2, protection class IP20
• Compact build — small dimensions and low weight (~80 g) minimize space and cabinet load
• Operating ambient temperature range: –5 °C to +55 °C (storage: –25 °C to +70 °C) — suitable for typical control-room conditions
• Reliability — long MTBF (mean time between failures) rating, supporting stable long-term operation
• Compliance with industrial and safety standards for communication modules / expansion accessories

Applications

The 7KM9300-0AB01-0AA0 module is used to expand the communication capabilities of a baseline power-monitoring or energy-metering device (like PAC3200/PAC4200), enabling integration into a PROFIBUS DP network for remote monitoring, data collection, energy management, and automation control. Typical use-cases include industrial energy monitoring, power-distribution panels, building-energy management systems, factory automation, and scenarios where centralized data collection of voltage, current, power, and energy metrics is required. This module helps embed energy meters into larger SCADA, BMS or automation systems without replacing existing hardware — offering a cost-effective upgrade path for smart monitoring and networked control.
