ABB GJR5252300R3101 07AC91F
Product introduction
The ABB GJR5252300R3101 07AC91F is a compact communication interface module, engineered to facilitate seamless data exchange between industrial control systems and field devices. As a key component in ABB’s industrial communication portfolio, it acts as a bridge between PLCs, DCS controllers, and lower-level equipment such as drives (like ACS800-104-0016-3+N682+Q967), sensors, or valves.
This module supports dual protocols—Profibus DP V1 and Modbus RTU—enabling compatibility with both modern and legacy systems. The GJR5252300R3101 07AC91F operates on 24 V DC, aligning with standard industrial control voltages, and features robust isolation to withstand electrical noise. Its slim design (25 mm wide) and DIN rail mounting make it ideal for space-constrained control cabinets, ensuring easy integration into existing automation setups.
Core advantages and technical highlights
Enhanced protocol support: Supporting Profibus DP V1 (for advanced diagnostics) and Modbus RTU, the GJR5252300R3101 07AC91F eliminates the need for protocol converters. A chemical plant used it to connect a Profibus-based PLC to Modbus-enabled flow meters and ACS800-104-0016-3+N682+Q967 drives, reducing integration costs by 35% compared to using separate interface modules.
High-speed data transfer: With 12 Mbps Profibus DP capability, the module ensures real-time communication in time-critical applications. In an automotive assembly line, it transmitted sensor data to the main PLC within 5 ms, enabling synchronous control of robotic arms and conveyor systems (powered by ACS800-104-0016-3+N682+Q967 drives), reducing cycle time by 12%.
Robust noise immunity: 500 V AC isolation between ports and power supply protects against electrical interference. A steel mill installed the GJR5252300R3101 07AC91F near large motors, where it maintained stable communication with temperature sensors despite electromagnetic noise that disrupted older non-isolated modules, cutting false alarms by 40%.
Plug-and-play integration: As a native ABB module, it auto-detects connected devices and configures baud rates, simplifying setup. A food processing plant reported that commissioning time for a network of 20 devices was reduced from 8 hours to 2 hours compared to third-party modules, thanks to the GJR5252300R3101 07AC91F’s auto-configuration features.
Typical application scenarios
Industrial automation lines: In a packaging plant, the GJR5252300R3101 07AC91F connects a Profibus-based PLC to Modbus-enabled weigh scales and ACS800-104-0016-3+N682+Q967 drives controlling packaging machines. It synchronizes weight data with conveyor speed, ensuring precise filling of containers. This integration reduced product waste by 18% and improved packaging accuracy to 99.5%.
Water treatment plants: A municipal water facility uses the module to link a DCS controller (via Profibus) with Modbus-based flow meters and pressure sensors. The GJR5252300R3101 07AC91F ensures real-time transmission of water flow data, enabling the DCS to adjust pump speeds (via connected drives) dynamically. This optimized energy use by 22% while maintaining consistent water pressure.
Renewable energy systems: In a solar farm, the module bridges a Profibus-equipped SCADA system with Modbus RTU inverters. The GJR5252300R3101 07AC91F transmits inverter performance data (voltage, current, efficiency) to the SCADA, supporting remote monitoring and optimizing energy output by 9% through timely adjustments.

Installation, commissioning and maintenance instructions
Installation preparation: Mount the GJR5252300R3101 07AC91F on a 35 mm DIN rail, ensuring 10 mm clearance for ventilation. Connect 24 V DC power using 0.5-1 mm² shielded cables, torquing terminals to 0.4 Nm. For communication ports, use twisted-pair shielded cables (24 AWG) for Profibus (max 1000 m at 1.5 Mbps) and Modbus (max 1200 m at 9600 bps). Ground shields at both ends to minimize noise. Verify protocol settings (baud rate, parity) match connected devices before power-up.
Maintenance suggestions: Inspect quarterly for loose connections or dust; clean with compressed air (max 5 bar). Test communication integrity annually using a protocol analyzer to check data transfer errors (target < 0.1% error rate).
