6GK1500-3AA10
PROFIBUS Optical Bus Terminal 2.0 (OBT)
Optical connection for PROFIBUS DP nodes without an integrated optical interface
Bridge the Interface Gap in PROFIBUS DP
A purpose-built optical bus terminal for network layouts that need an optical connection at a PROFIBUS node.
|
What it does
The OBT connects PROFIBUS nodes that do not have an integrated optical interface to an optical PROFIBUS DP network. Its purpose is network-interface adaptation, not general-purpose Ethernet switching.
|
Connection planning
Check the existing PROFIBUS DP topology, node interface type, optical cable arrangement and required connectors. The optical terminal must match the intended network design.
|
Ordering detail
The specified product is supplied without a simplex plug. Confirm connector and cable-end requirements before ordering so the terminal and installation accessories are planned together.

Check the network before you buy
For a replacement request, provide the OBT model, the connected node type, the intended optical link and the connector arrangement. This helps prevent ordering an interface component that does not match the existing PROFIBUS topology.
Network Role & Component Comparison
| Component type |
Primary role |
When to choose it |
| 6GK1500-3AA10 OBT |
Provides an optical PROFIBUS DP connection for a node without an integrated optical interface |
When the node and optical segment need the specified OBT interface |
| PROFIBUS node with integrated optical interface |
Connects to optical PROFIBUS through its built-in interface |
When the installed node already provides the required optical interface |
| Copper PROFIBUS connection component |
Supports a copper-side PROFIBUS connection |
When the network segment and node interface are designed for copper rather than optical transmission |
Selection guidance: choose by interface type and network topology, not by enclosure appearance. Confirm the optical cable and plug requirements, the node's existing interface and the role of the replacement point before making a substitution.

Frequently Asked Questions
1. Is 6GK1500-3AA10 suitable for a PROFIBUS node without an optical interface?
Yes. Its stated role is to connect PROFIBUS nodes without an integrated optical interface to optical PROFIBUS DP. Check the exact node interface and network topology before ordering.
2. Does 6GK1500-3AA10 include the simplex plug?
The specified product is described as being supplied without a simplex plug. Check the connector style and quantity required by your optical cable installation.
3. Can 6GK1500-3AA10 replace a copper PROFIBUS connector?
Not automatically. This OBT is intended for optical PROFIBUS DP connectivity. A copper connection component serves a different interface role, so the cable type and network segment must be checked.
4. What should I confirm when replacing 6GK1500-3AA10 in an existing network?
Confirm the full part number, connected node, optical link arrangement, connector requirement and the intended position in the PROFIBUS DP topology. These checks are more useful than comparing appearance alone.
5. What details help AMIKON quote 6GK1500-3AA10 correctly?
Send the quantity, delivery destination, required date and the current network interface details. If plugs or optical cables are also needed, specify those requirements separately.
