Introduction to the ABB 07KP93
When your industrial automation system requires reliable Modbus RTU communication, the ABB 07KP93 GJR5253200R1161 communication module delivers a proven solution. This interface module connects external devices to the Advant Controller 31 system using two serial MODBUS RTU interfaces. As a spare part, it ensures continuity for existing installations.
Technical Specifications Breakdown
The 07KP93 features two serial interfaces configurable as EIA RS-232 or EIA RS-485 (COM3, COM4). Operating modes include Master/Slave, Slave/Master, and Slave/Slave. It also includes one parallel networking interface for connecting to the AC 31 basic unit. The module requires a rated supply voltage of 24 V DC, with typical power dissipation of 2.5 W (max 5 W). Maximum current consumption at rated voltage is 210 mA, and at 30 V supply it draws 170 mA. Protection against reversed terminal connection is built in. The module weighs 0.58 kg and measures 140 x 120 x 85 mm (width x height x depth).
Industry Applications
In manufacturing environments, the ABB 07KP93 serves as a communication gateway between AC 31 controllers and Modbus RTU devices such as drives, sensors, and remote I/O. For example, in a material handling system, it enables a master PLC to poll multiple slave devices over RS-485, ensuring coordinated conveyor control. Its dual interface design allows one port to act as master while the other operates as slave, supporting flexible network topologies.
Installation & Setup Guidance
Mount the 07KP93 on a DIN rail per DIN EN 50022–35, 15 mm deep. The DIN rail sits centered between the module's upper and lower edges. Alternatively, fasten it with four M4 screws. Use removable terminal blocks with screw-type terminals, accepting conductor cross-sections up to 2.5 mm². The scope of delivery includes one 5-pole terminal block (5.08 mm grid) and a cable with terminals for earth connection. Ensure the supply voltage is 24 V DC and observe polarity protection.
Maintenance & Reliability
Regularly inspect the module for secure mounting and clean terminal connections. The four yellow LEDs (LED1...LED4) assist in diagnosing communication status, while the green RUN, red ERR, and green Supply LEDs provide operating and error displays. Periodic verification of these indicators helps identify issues early. The module's electrical isolation between interfaces and the rest of the unit enhances reliability in noisy industrial environments.
Compatibility & Integration
The 07KP93 communicates with AC 31 basic units using function blocks and connection elements via programming software 907 KP 93. It supports Modbus RTU protocol over both RS-232 and RS-485. When integrating, confirm that your controller firmware and software version are compatible. The module is designed as a spare part for existing systems, so verify lifecycle status with SpareTechPLC before ordering.
Selection Guide & Purchasing Advice
Before purchasing the ABB 07KP93 GJR5253200R1161, confirm your system's compatibility with Advant Controller 31 and Modbus RTU. Check that the supply voltage matches 24 V DC and that your DIN rail or mounting hardware meets the specified dimensions. SpareTechPLC stocks this module with a minimum order quantity of one piece.

Frequently Asked Questions
Q1: What is the difference between COM3 and COM4 on the 07KP93?
Both ports support EIA RS-232 or RS-485, but they can be configured independently. For example, COM3 can act as a master while COM4 operates as a slave, or both can be slaves. Master-master mode is not supported.
Q2: Can the 07KP93 be used with other ABB controllers besides AC 31?
The module is specifically designed for the Advant Controller 31 system. Communication with AC 31 basic units is performed using function blocks and connection elements from software 907 KP 93. For other controllers, consult ABB documentation.
Q3: What does the ERR LED indicate?
The red ERR LED signals an error condition. Refer to the module's manual for specific error codes. The RUN (green) and Supply (green) LEDs provide additional status information.
Q4: Is electrical isolation provided between the serial interfaces?
Yes, the interfaces are electrically isolated from each other and from the rest of the unit, which helps protect against ground loops and noise.
Q5: What is the maximum cable length for RS-485 connections?
While not specified in the data, standard RS-485 practice supports up to 1200 meters. Ensure proper termination and grounding per EIA RS-485 guidelines.
