The Allen Bradley 2198-TCON-24VDCIN36 Kinetix 5500/5700 DC Input Connector is an electrical connection accessory used to introduce 24V DC control power into a shared-bus servo drive arrangement. It belongs to the Bulletin 2198 accessory range and is used with compatible Kinetix 5500 and Kinetix 5700 drive systems.
In a multi-axis machine, several servo drives may operate from a common control system while requiring a coordinated 24V DC supply for their control electronics. Rather than routing an independent control-power connection to every module, a shared control-power arrangement allows the supply to enter the drive cluster through an input connector and continue through compatible T-connectors and bus bars. This reduces wiring complexity and gives the cabinet a more organized power distribution layout.
The 2198-TCON-24VDCIN36 serves as the entry point for the 24V DC control-power connection system. It accepts the incoming control-power wiring and provides the interface needed to extend the supply through compatible modules. In a machine with multiple servo axes, this arrangement can simplify panel wiring and make the control-power distribution easier to inspect during commissioning and maintenance.
The connector is intended for control power, not the main motor power circuit. The 24V DC supply supports the control-power requirements of the connected drive system, while the drive’s separate power connections handle the electrical energy used to operate the motors. Keeping these functions distinct is essential when laying out the cabinet and preparing the wiring.
The shared-bus arrangement also has defined installation requirements. The input connector starts the 24V DC connection system, while compatible T-connectors and bus bars extend it across the drive cluster. The connection must be arranged in the correct direction, and the total control-power current must remain within the system’s permitted rating. The documented maximum current for this connection system is 40 A.
For maintenance engineers, the main concerns are secure wiring, correct polarity, connector seating, bus-bar alignment, and the total load placed on the 24V DC supply. A loose connection or incorrectly assembled shared-bus section can affect several drive modules rather than a single axis. Inspecting the entire control-power distribution path is therefore important when multiple drives report control-power-related faults.

The 2198-TCON-24VDCIN36 introduces the incoming 24V DC control supply into the shared control-power connection system. Once installed, compatible bus components carry that supply along the drive cluster, allowing the connected modules to receive control power through the intended distribution arrangement.
24V DC Supply → 2198-TCON-24VDCIN36 → Shared-Bus Connectors → Compatible Drive Modules
During installation, the incoming positive and common conductors are connected to the designated terminals. The input connector is then installed in the appropriate position within the drive cluster. Compatible T-connectors and bus bars extend the control-power connection to the downstream modules.
For example, a packaging machine may use several Kinetix servo drives to control separate conveyor, indexing, and positioning axes. The 24V DC supply enters the control-power bus through the 2198-TCON-24VDCIN36. The shared-bus components then distribute the supply through the connected drive arrangement, reducing the need for individual incoming control-power connections at each module.
The direction of the connection system matters. The 24V DC bus must extend from left to right through the designated connector arrangement. If the input connector is installed incorrectly or a bus-bar connection is not fully engaged, the control-power distribution may not operate as intended. Correct placement and secure engagement should be confirmed before the system is energized.
Current capacity must also be considered when designing the control-power distribution. The shared connection system has a maximum rating of 40 A. If the combined control-power demand reaches the permitted limit, the documented system arrangement allows another compatible input wiring connector to establish an additional 24V control-power entry point. The supply design and wiring must still comply with the requirements of the selected equipment.
The connector does not regulate the 24V DC supply or convert it into motor power. Its role is to establish the electrical connection through which the control supply enters the shared-bus system. The upstream supply remains responsible for delivering the correct voltage and sufficient current, while the drive modules use the distributed power for their control functions.
The 2198-TCON-24VDCIN36 serves as the control-power entry component in a shared-bus drive arrangement. It connects the incoming 24V DC supply to the distribution components that extend control power across compatible servo drive modules.

The connector is most useful in installations where compatible drive modules share a 24V DC control-power distribution system. Its selection must account for the drive family, bus arrangement, supply capacity, and overall control-power demand.
If several drive modules lose control power at the same time, inspect the incoming 24V DC supply and shared-bus connection path before investigating each drive individually. A fault at the input connector or a shared connection can affect multiple modules.

The 2198-TCON-24VDCIN36 is used to introduce 24V DC control power into the shared control-power connection system. A main DC-bus connector carries power for the drive’s power-conversion section. These circuits serve different purposes and must not be treated as interchangeable.
The practical number depends on the combined control-power demand and the approved bus arrangement. The shared 24V DC connection system has a maximum current rating of 40 A. The number of connected modules should therefore be determined from their control-power requirements rather than from the physical number of available connector positions alone.
The connector system uses a defined orientation for its input connector, T-connectors, and bus bars. Following the specified direction ensures that the components engage in the intended arrangement. Incorrect positioning can prevent proper connection or produce an unsuitable distribution layout.
Start by checking the 24V DC supply, incoming wiring polarity, and the input connector’s terminal connections. Then inspect the shared bus bars and T-connectors for incomplete engagement or damage. A common supply or distribution fault can affect several drive modules at once, so the shared connection path should be checked before treating the problem as multiple independent drive failures.
