Product Description

Siemens 7RQ0201-1CX00 Relay Socket – 3 Changeover Contacts, 11-Pin, 10A, DIN Rail Mounting

The Siemens 7RQ0201-1CX00 is a DIN rail-mounted relay socket designed for compatible Siemens 7RQ plug-in relays with 3 changeover contacts (3CO). It has an 11-pin connection, a 10 A rating category, and screw-terminal connections for panel wiring. Siemens' official SINOVA 7RQ documentation identifies this exact article as the DIN rail mounting socket for 3 CO, 10 A relays.

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

Siemens 7RQ0201-1CX00 Relay Socket

The 7RQ0201-1CX00 belongs to the Siemens SINOVA 7RQ plug-in relay system. It provides the mechanical support and electrical interface required for a compatible 3CO plug-in relay.

The socket is designed for DIN rail mounting, making it suitable for organized installation in industrial control panels and electrical enclosures. Siemens specifies this article under the 3CO, 10 A socket category.

3 Changeover Contacts

The socket is designed for a relay with 3 changeover contacts (3CO).

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

Three changeover contacts allow several independent switching functions to be handled using one relay, depending on the control circuit design.

Typical applications include:

• Control-circuit switching

• Status indication

• Electrical interlocking

• Signal switching

• Auxiliary control

• Machine-control circuits

The actual switching load must remain within the ratings of the compatible relay and complete circuit.

11-Pin Connection

The 7RQ0201-1CX00 uses an 11-pin connection arrangement for the compatible 3CO relay. Siemens' official documentation identifies the 3CO relay family with an 11-pin configuration.

The relay installed in the socket must have the correct 11-pin mechanical and electrical configuration.

10 A Rating

The exact socket belongs to the 3CO, 10 A category. Siemens' current documentation lists the 7RQ0201-1CX00 socket with a corresponding 10 A 3CO relay family.

The actual permissible switching load depends on the complete relay, load type, switching category and circuit conditions.

DIN Rail Mounting

The 7RQ0201-1CX00 is specifically designed for DIN rail mounting.

DIN rail installation is widely used in industrial control panels because it provides:

• Standardized component mounting

• Organized panel layouts

• Faster installation

• Easy maintenance

• Convenient replacement

Siemens' official 7RQ documentation identifies the article under DIN rail mounting socket.

Panel Mounting and Screw Terminals

The product description specifies panel mounting with screw-terminal connections. This makes it suitable for conventional industrial control-panel wiring where secure and serviceable terminal connections are required.

Screw terminals provide a practical interface for connecting the socket to external control circuitry.

Relay Socket Function

The socket provides two primary functions:

Mechanical support: Holds the compatible plug-in relay securely.

Electrical interface: Connects the relay terminals to the fixed panel wiring.

Because the relay is plug-in, the relay can be replaced while the socket and fixed wiring remain installed, simplifying routine maintenance.

Compatible Plug-In Relay

The 7RQ0201-1CX00 should be paired with a compatible Siemens 7RQ 3CO plug-in relay matching the required:

• 3CO contact configuration

• 11-pin arrangement

• 10 A category

• Coil voltage

• Mechanical dimensions

The Siemens 7RQ range includes 3CO relays with different control-supply voltages, so the correct relay article must be selected separately according to the control circuit.

Industrial Control Applications

The 7RQ0201-1CX00 can be considered for compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control systems

• Relay interface circuits

• Process-control equipment

• Signal switching

• Equipment status indication

• Auxiliary control circuits

• Maintenance and replacement applications

Its DIN rail format makes it especially suitable for conventional industrial control-panel layouts.

Multiple Switching Functions

The 3CO configuration enables the associated relay to provide three changeover switching functions.

Depending on circuit design, these contacts can be used for:

• Multiple status signals

• Control signal distribution

• Electrical interlocking

• Alarm circuits

• Auxiliary switching

• Equipment monitoring

The final application should always follow the electrical ratings of the relay and connected load.

Difference from 2CO, 10A Socket

The Siemens 7RQ0211-1BX00 is a 2CO, 10 A DIN rail socket, whereas 7RQ0201-1CX00 is a 3CO, 10 A DIN rail socket.

Therefore, these articles are different even though both are rated in the 10 A category.

Difference from 4CO, 7A Socket

The 7RQ0201-1DX00 is the 4CO, 7 A DIN rail socket, while 7RQ0201-1CX00 is the 3CO, 10 A version. Siemens' official documentation differentiates these by contact configuration and rating.

The exact relay configuration should therefore be verified before ordering.

Difference from PCB-Mounted Sockets

The Siemens 7RQ range provides different socket types depending on mounting method. The official Siemens brochure lists PCB sockets for 1CO, 2CO and 4CO variants, but the 3CO socket is specified as a DIN rail mounting article, 7RQ0201-1CX00.

This makes 7RQ0201-1CX00 the appropriate choice where a DIN rail-mounted 3CO, 10 A interface is required.

Replacement and Maintenance

The 7RQ0201-1CX00 can be used as a replacement socket in compatible Siemens 7RQ installations.

Before ordering, verify:

• Existing relay article

• 3CO contact configuration

• 11-pin arrangement

• 10 A category

• DIN rail requirement

• Screw-terminal connection

• Relay coil voltage

• Mechanical compatibility

This prevents selecting a socket with a different contact count or pin configuration.
