Product Description

Siemens 7RQ0212-1BX00 Relay Socket – 2 Changeover Contacts, 5-Pin, 10A, PCB Mount

The Siemens 7RQ0212-1BX00 is a relay socket for PCB mounting, designed for relays with 2 changeover contacts (2CO) and a 5-pin connection arrangement. The socket is rated for applications up to 10 A and is intended for mounting directly onto a printed circuit board in industrial control and electrical applications.

For SB Smart, this product is positioned as a Siemens industrial electrical accessory for relay mounting, control panels, PCB assemblies, machine control circuits, replacement and procurement requirements.

Siemens 7RQ0212-1BX00 Relay Socket

The 7RQ0212-1BX00 belongs to the Siemens relay accessory range and provides a socket interface for a compatible relay. Its PCB-mounted construction makes it suitable for electronic control boards and compact industrial control assemblies where the relay needs to be installed and serviced conveniently.

The socket is specified for relays having a 2 changeover contact configuration and a 5-pin connection arrangement.

2 Changeover Contacts

A 2 changeover contact arrangement provides two changeover switching functions. Each changeover contact can transfer a common connection between a normally closed and a normally open path according to the relay state.

This type of contact arrangement can be used for compatible:

• Control circuits

• Status switching

• Interlocking

• Signal transfer

• Machine-control logic

• Auxiliary switching applications

The exact contact use depends on the relay installed and the circuit design.

5-Pin Connection

The 7RQ0212-1BX00 is specified as a 5-pin relay socket.

The 5-pin arrangement provides the electrical interface between the compatible relay and the PCB. Before installation, the relay pin configuration should be checked carefully to ensure it matches the socket.

Correct pin assignment is essential for reliable relay operation.

10 A Rating

The socket is specified for a 10 A rating. This rating should be considered together with the actual electrical characteristics of the relay and the connected circuit.

For selection, users should verify:

• Voltage

• Current

• Contact load

• Switching category

• Relay compatibility

• PCB track capacity

The connected load should remain within the applicable ratings of the complete relay and socket arrangement.

PCB Mounting

The 7RQ0212-1BX00 is designed for printed-circuit-board mounting.

PCB mounting provides a compact solution for control equipment and allows the relay socket to be integrated directly into an electronic or electrical control board.

This makes it suitable for:

• Control boards

• Relay interface circuits

• Industrial electronics

• Machine-control PCBs

• Electrical control assemblies

• Panel electronics

Relay Socket Function

A relay socket provides the mechanical and electrical interface between the relay and the control circuit.

Using a socket can make relay replacement easier because the relay can be removed without desoldering the socket from the PCB.

The socket therefore supports convenient maintenance and replacement in compatible PCB assemblies.

Industrial Control Applications

The 7RQ0212-1BX00 can be considered for applications such as:

• Industrial control panels

• PCB-based relay interfaces

• Machine-control circuits

• Electrical control systems

• Switching interfaces

• Automation control boards

• Equipment signalling circuits

• Maintenance and replacement applications

The final application should be selected according to the relay's electrical and mechanical specifications.

Relay Compatibility

The most important selection factor is compatibility between the socket and the relay.

Before purchasing the 7RQ0212-1BX00, verify:

• Relay series

• Relay pin arrangement

• Number of contacts

• Contact configuration

• Coil arrangement

• PCB footprint

• Rated current

• Required mounting method

A 5-pin socket should only be used with a relay designed for the corresponding 5-pin connection arrangement.

Compact PCB Relay Interface

The PCB-mounted format helps reduce wiring and panel space compared with individually wired relay sockets.

For compact control assemblies, a PCB relay socket can provide:

• Organized component placement

• Reduced point-to-point wiring

• Easier relay replacement

• Consistent mounting

• Simplified PCB assembly

Replacement and Maintenance

The 7RQ0212-1BX00 can be useful as a replacement socket in compatible relay PCB assemblies.

Before ordering a replacement, confirm the existing socket's:

• Article number

• Pin count

• Contact configuration

• Mounting method

• PCB footprint

• Electrical rating

This is particularly important because relay sockets with similar appearances may have different pin arrangements.

Suitable for Electrical Panel Builders and Industrial Buyers

The Siemens 7RQ0212-1BX00 is relevant for:

• Electrical panel builders

• Industrial buyers

• PCB designers

• Maintenance departments

• Electrical contractors

• Machine builders

• OEM maintenance teams

• Electrical product dealers

• Replacement-part procurement

For SB Smart, the product is positioned around industrial electrical product supply and procurement, without claiming automation integration or automation-service work.
