The ABB S-053H 3BHB012897R0007 rack typically refers to the ABB DRA02 rack, which is part of the Freelance 2000 series. The following provides a detailed introduction:
Basic composition: The basic composition of a standard rack controller includes a central unit, which comprises a CPU module, a connection module, and 8 undefined slots for I/O modules. Up to 4 expansion I/O stations can be installed, with each I/O station capable of housing 9 I/O modules and connecting to the central unit.
Slot configuration: Slot A is used for installing LINK modules, Slot 0 is used for installing CPU modules, Slot 1 can be used for installing redundant CPU modules, and Slots 1-8 can be used for installing any I/O modules.
I/O module installation capability: It can install up to 10 Freelance 2000 I/O modules and supports various types of ABB and third-party I/O modules, providing flexibility for system expansion and configuration.
Connection method: The rear of the rack is equipped with a printed circuit board (PCB), and a plug-in connection socket is installed for connecting with the I/O module. The lower part of the rack features mounting rails to ensure accurate insertion of the module into the connection socket. The connection socket is connected to the DigNet P (CAN bus) bus through the PCB. The CPU drives the I/O module via the DigNet P bus and distributes system power to the I/O module simultaneously.
Mechanical design: Adopt a sturdy and robust structural design, with the module being fully enclosed in metal. There are two screws on the upper and lower parts of the module’s front panel, used to secure the module to the rack. The protection level of the rack is IP20, which can prevent the intrusion of solid foreign objects larger than 12mm.
Power supply mode: The Freelance 2000 rack provides 24VDC auxiliary power through a DPW power module. The power module converts 24VDC into system power of different voltage levels required by the module through a DC/DC converter.
Working environment: The operating temperature range is from -20°C to +70°C, which can adapt to certain temperature variations in industrial environments and meets the application requirements of most industrial settings.
Other features: The module can be hot-swapped, facilitating system maintenance and upgrades; the CPU and I/O modules are equipped with temperature detection, allowing real-time monitoring of the module’s working status to ensure stable system operation.

Detailed introduction and full series models of ABB S-053H 3BHB012897R0007 rack
The ABB S-053H 3BHB012897R0007 rack, also known as the DRA02 rack, is a module rack from the ABB Freelance 2000 series. Here is a detailed introduction:
Basic characteristics: It adopts 24V DC power supply, measures 130x100x190mm in size, has a protection level of IP20, can operate in an ambient temperature range of -20°C to +70°C, and features Ethernet/LP communication interfaces.
Slot configuration: Slot A is used for installing LINK modules, slot 0 for CPU modules, slot 1 for redundant CPU modules, and slots 1-8 for any I/O modules.
I/O module installation capability: It can install up to 10 Freelance 2000 I/O modules and supports various types of ABB and third-party I/O modules, providing flexibility for system expansion and configuration.
Connection method: The rear of the rack is equipped with a printed circuit board, and a plug-in connection socket is installed for connecting with the I/O module. The lower part of the rack features mounting rails, allowing the module to be accurately inserted into the connection socket. The connection socket is connected to the DigNet P (CAN bus) bus through the printed circuit board. The CPU drives the I/O module via the DigNet P bus and distributes system power to the I/O module simultaneously.
Mechanical design: The structure is sturdy and robust, with the front panel connection module being fully enclosed in metal. There are two screws on the upper and lower parts of the module’s front panel, used to secure the module to the rack.
Power supply mode: The Freelance 2000 rack provides 24VDC auxiliary power through the DPW power module.
Other features: The module can be hot-swapped, and both the CPU and I/O modules are equipped with temperature detection, allowing real-time monitoring of the module’s operating status to ensure stable system operation. Additionally, the I/O modules can be placed arbitrarily on the rack, with EMI compliant with IEC801 standards. The module terminals utilize front-panel wiring technology, providing a high mean time between failures (MTBF).
Regarding the full series of models for the ABB S-053H (DRA02) rack, there is currently no explicit mention in public information that there are multiple models. Typically, this rack mainly refers to the aforementioned standard configuration model, DRA02, which is used to meet the basic architecture and expansion requirements of the Freelance 2000 series PLC system. If there are other derivative models, they may exist due to special application scenarios or customization needs, but relevant information may be limited and uncommon.
