ABB 07AC91 GJR5252300R0101

Product introduction

The ABB 07AC91 GJR5252300R0101 is a compact communication interface module, designed 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 (such as FCP270 P0917YZ), and lower-level equipment like drives, sensors, or valves.

This module supports dual protocols—Profibus DP and Modbus RTU—enabling compatibility with both modern and legacy systems. The 07AC91 GJR5252300R0101 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

Dual-protocol flexibility: Supporting both Profibus DP and Modbus RTU, the 07AC91 GJR5252300R0101 eliminates the need for multiple interface modules. A food processing plant used it to connect a new Profibus-based PLC with legacy Modbus sensors, avoiding a complete system upgrade and saving 40% in integration costs.

High-speed data transfer: With a Profibus DP rate of up to 12 Mbps, the module ensures real-time communication. In a high-speed bottling line, it transmitted sensor data to the PLC within 10 ms, enabling immediate adjustments to filling machines and reducing product waste by 25%.

Robust noise immunity: 500 V AC isolation between ports and power supply protects against electrical interference. A steel mill installed the 07AC91 GJR5252300R0101 near large motors, where it maintained stable communication with conveyor drives despite electromagnetic noise that disrupted older non-isolated modules.

Compact integration: At 25 mm wide, the module fits into crowded cabinets. An automotive plant replaced three single-protocol modules with two 07AC91 GJR5252300R0101 units, freeing up 50% of rail space for additional control components.

Typical application scenarios

Industrial automation lines: In an automotive assembly line, the 07AC91 GJR5252300R0101 connects a Profibus-based PLC to Modbus-enabled robotic arms and Profibus-driven conveyor drives. It consolidates data from both protocols, allowing the PLC to synchronize arm movements with conveyor speed, reducing cycle time by 15%.

Water treatment plants: A municipal water facility uses the module to link a DCS controller (via Profibus DP) with Modbus-based flow meters and pressure sensors. The 07AC91 GJR5252300R0101 ensures real-time transmission of water flow data, enabling the DCS to adjust pump speeds dynamically and cut energy use by 20%.

Renewable energy systems: In a solar farm, the module bridges a Profibus-equipped SCADA system with Modbus RTU inverters. The 07AC91 GJR5252300R0101 transmits inverter performance data (voltage, current, efficiency) to the SCADA, supporting remote monitoring and optimizing energy output by 8%.

Installation, commissioning and maintenance instructions

Installation preparation: Mount the 07AC91 GJR5252300R0101 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). Replace the 07AC91 GJR5252300R0101 if ports show physical damage or if communication drops exceed 1% of transmissions. Store spare modules in anti-static bags at 10-30°C, avoiding exposure to moisture.
