Product Description

Siemens 7RQ0202-1BX00 Relay Socket – 2 Changeover Contacts, 8-Pin, 6A, PCB Mount

The Siemens 7RQ0202-1BX00 is a PCB-mounted relay socket designed for compatible 2 changeover contact (2CO) plug-in relays. It has an 8-pin connection arrangement and is rated for 6 A applications. Siemens' official SINOVA 7RQ documentation identifies 7RQ0202-1BX00 as the PCB mounting socket for the 2CO, 6 A, 8-pin relay configuration.

For SB Smart, this product is suitable for PCB-based industrial control circuits, relay interfaces, electrical control boards, machine-control equipment, maintenance and replacement applications.

Siemens 7RQ0202-1BX00 Relay Socket

The 7RQ0202-1BX00 is part of the Siemens SINOVA 7RQ plug-in relay system. It provides the mechanical and electrical interface between a compatible plug-in relay and the printed circuit board.

The Siemens 7RQ product documentation clearly specifies this article under PCB mounting for the 2CO, 6 A relay category.

2 Changeover Contacts

The socket is intended for relays with 2 changeover contacts, commonly referred to as 2CO or 2 C/O.

Each changeover contact provides a common connection that switches between its normally open and normally closed paths according to the relay state.

This configuration can support applications such as:

• Control-circuit switching

• Signal switching

• Status indication

• Interlocking

• Machine-control circuits

• Auxiliary switching

The actual switching function depends on the relay installed in the socket.

8-Pin Configuration

The exact 7RQ0202-1BX00 uses an 8-pin interface for the compatible 2CO relay. Siemens' official documentation lists this article as the PCB mounting socket in the 8-pin, 2CO, 6 A category.

The relay must have the correct 8-pin mechanical and electrical configuration before installation.

6 A Rating

The socket is specified for the 2CO, 6 A relay category. Siemens identifies the corresponding 7RQ socket under the 6 A configuration.

The actual permissible load should always be selected according to the ratings of the complete relay, socket and connected circuit.

PCB Mounting

The 7RQ0202-1BX00 is designed for printed-circuit-board mounting.

This allows the relay socket to be integrated directly into an electronic or electrical control board, providing a compact alternative to separately wired relay mounting.

PCB mounting can help provide:

• Compact component placement

• Organized relay interfaces

• Reduced point-to-point wiring

• Easy relay replacement

• Consistent PCB assembly

Relay Socket Function

A relay socket provides both the physical support and electrical connection for the compatible plug-in relay.

The socket remains mounted on the PCB while the relay can be removed and replaced separately, which can simplify maintenance.

This is especially useful in control equipment where relays may need to be replaced periodically.

Compatible Plug-In Relay

The 7RQ0202-1BX00 should be used with a compatible Siemens 7RQ plug-in relay having the required 2CO, 8-pin, 6 A configuration.

Siemens documentation lists corresponding 7RQ relays with 2CO, 6 A and 8-pin arrangements, including variants with different coil voltages and standard features such as a mechanical flag and LED indication.

Before ordering, verify the relay:

• Contact configuration

• Pin arrangement

• Coil voltage

• Mechanical dimensions

• Electrical rating

Compact PCB Relay Interface

The PCB-mounted format makes the 7RQ0202-1BX00 suitable for compact industrial electronic assemblies.

A plug-in relay mounted through a socket can simplify servicing because the fixed PCB connection remains in place when the relay itself is replaced.

Industrial Control Applications

The 7RQ0202-1BX00 can be considered for compatible applications such as:

• Industrial control boards

• Machine-control circuits

• Relay interface modules

• Electrical control systems

• Process-control equipment

• Signal switching circuits

• Industrial machinery

• Panel electronics

• Maintenance and replacement applications

The final application must be based on the relay and circuit specifications.

Difference from DIN Rail Socket

Siemens offers separate mounting sockets for the same 2CO, 6 A relay configuration.

7RQ0202-1BX00: PCB mounting

7RQ0201-1BX00: DIN rail mounting

Therefore, the mounting method should be selected according to the installation design.

Difference from 7RQ0212-1BX00

Siemens also lists 7RQ0212-1BX00 as a PCB-mounted socket for the higher 2CO, 10 A category. In contrast, 7RQ0202-1BX00 is the 2CO, 6 A PCB-mounted socket.

This distinction is important when replacing a relay socket because the 10 A and 6 A versions are different articles.

Difference from 7RQ0202-1DX00

The 7RQ0202-1DX00 is the 4CO, 7 A PCB-mounted socket, while 7RQ0202-1BX00 is the 2CO, 6 A PCB-mounted socket. Siemens' official documentation differentiates these articles by contact configuration and rated current.

Replacement and Maintenance

The 7RQ0202-1BX00 is suitable for replacement of a compatible PCB-mounted relay socket.

Before ordering, verify:

• Existing relay article

• 2CO contact configuration

• 8-pin connection

• 6 A rating

• PCB footprint

• Coil voltage of the relay

• Mounting arrangement

This ensures the replacement socket matches the existing Siemens relay assembly.
