Product Description

Siemens 7RQ0211-1BX00 Relay Socket – 2 Changeover Contacts, 5-Pin, 10A, DIN Rail Mounting

The Siemens 7RQ0211-1BX00 is a relay socket with 2 changeover contacts, 5-pin connection, 10 A rating and DIN rail mounting. It features screw-terminal connections and is designed for compatible plug-in relays used in industrial control and electrical applications. Current product listings identify it as a Siemens 7RQ relay socket for DIN rail mounting.

For SB Smart, this product is suitable for industrial relay assemblies, control panels, machine-control circuits, electrical cabinets, maintenance and replacement applications.

Siemens 7RQ0211-1BX00 Relay Socket

The 7RQ0211-1BX00 belongs to the Siemens 7RQ relay accessory range and provides a dedicated mounting and connection interface for compatible plug-in relays. The socket is designed for DIN rail mounting, making it suitable for installation inside industrial control panels and electrical cabinets.

Its screw-terminal arrangement provides a practical connection method for field wiring while the socket supports the relay mechanically.

2 Changeover Contacts

The relay socket is designed for a relay with 2 changeover contacts, also commonly referred to as 2 C/O or 2 CO.

A changeover contact provides:

• Common contact

• Normally Open contact

• Normally Closed contact

With two changeover contacts, the compatible relay can provide two independent switching functions.

These contacts can be used in applications such as:

• Control circuits

• Status indication

• Auxiliary switching

• Interlocking

• Signal switching

• Machine-control circuits

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

5-Pin Connection

The 7RQ0211-1BX00 is specified as a 5-pin relay socket. The relay used with it must have the corresponding pin arrangement and mechanical compatibility.

Before installation, the relay's pin configuration should always be checked against the socket to ensure correct connection.

10 A Rating

The socket is specified with a 10 A current rating. Current product information confirms the 10 A rating for this article.

The actual switching capacity of the complete relay assembly depends on the relay and the connected load. Users should therefore consider the ratings of the relay, socket and circuit together rather than using the socket rating alone.

DIN Rail Mounting

One of the key features of 7RQ0211-1BX00 is its DIN rail mounting capability.

DIN rail mounting is commonly used in industrial control panels because it provides:

• Fast installation

• Organized panel layout

• Easy replacement

• Standardized mounting

• Reduced panel assembly time

The product is categorized under the DIN Rail mounting sub-family within the Siemens 7RQ range.

Screw Terminal Connection

The 7RQ0211-1BX00 uses screw terminals for electrical connection. This provides a conventional and service-friendly method for wiring the relay socket.

Screw-terminal connections are particularly useful in industrial control panels where maintenance teams may need to inspect, tighten or replace wiring connections.

Relay Socket Function

A relay socket separates the relay itself from the fixed panel wiring.

This arrangement can make maintenance easier because the relay can be removed from the socket without disconnecting every field wire individually.

The socket therefore provides both:

• Mechanical support for the relay

• Electrical connection between the relay and panel wiring

Industrial Control Applications

The 7RQ0211-1BX00 can be used in compatible applications such as:

• Industrial control panels

• Machine-control systems

• Electrical cabinets

• Relay interface circuits

• Signalling circuits

• Motor-control panels

• Industrial equipment

• Maintenance and replacement applications

Its DIN rail construction makes it suitable for conventional control-panel layouts.

Suitable for Plug-In Relays

The product is identified in current product information as a plug-in-relay accessory/socket.

This type of arrangement allows a compatible relay to be plugged into the socket while the socket remains permanently wired to the panel.

That can simplify relay replacement during maintenance.

Control and Switching Applications

Depending on the connected relay, the two changeover contacts can support multiple control functions.

For example, one contact set can be used for status indication while the second can be used for a separate control or interlocking function.

Typical uses include:

• Alarm indication

• Electrical interlocking

• Equipment status feedback

• Control signal switching

• Auxiliary circuit operation

• Machine sequence control

The actual application should be based on the relay's electrical specifications and circuit design.

Replacement and Maintenance

The 7RQ0211-1BX00 can be used as a replacement relay socket where an existing compatible 7RQ installation requires a new socket.

Before ordering, verify:

• Relay series

• Number of pins

• Contact configuration

• Current rating

• DIN rail requirement

• Terminal arrangement

• Mechanical relay compatibility

This is important because Siemens offers several relay sockets with different pin counts and contact arrangements.

Related Siemens Relay Sockets

The Siemens 7RQ range includes different relay sockets according to contact count and mounting requirements. Current listings show examples such as:

• 7RQ0201-1AX00 – 1 changeover contact, 5-pin, 10 A

• 7RQ0211-1BX00 – 2 changeover contacts, 5-pin, 10 A

• 7RQ0201-1BX00 – 2 changeover contacts, 8-pin, 6 A

• 7RQ0201-1CX00 – 3 changeover contacts, 11-pin, 10 A

• 7RQ0201-1DX00 – 4 changeover contacts, 8-pin, 7 A

This makes it important to select the exact socket according to the relay's contact arrangement and pin configuration.

Difference from 7RQ0201-1BX00

Although both articles support 2 changeover contacts, they are not the same socket.

7RQ0211-1BX00: 5-pin, 10 A, DIN rail mounting

7RQ0201-1BX00: 8-pin, 6 A, DIN rail mounting

This distinction is particularly important when replacing an existing relay socket.

Difference from PCB-Mounted Relay Socket

The 7RQ0211-1BX00 is intended for DIN rail mounting, whereas the related 7RQ0212-1BX00 is specified for a PCB-mounted installation.

Therefore:

7RQ0211-1BX00 = DIN rail mounting

7RQ0212-1BX00 = PCB mounting

The installation method should be matched to the control-panel design.

Panel Installation

The DIN rail mounting arrangement makes the 7RQ0211-1BX00 suitable for standard industrial electrical cabinets.

It can help maintain a neat panel layout where relay sockets are installed alongside:

• Circuit breakers

• Contactors

• Terminal blocks

• Control relays

• Interface modules

• Other DIN rail-mounted components

The final panel arrangement should maintain adequate clearance and wiring space.
