Product Description

Siemens 7RQ0201-1DX00 Relay Socket – 4 Changeover Contacts, 8-Pin, 7A, DIN Rail Mounting

The Siemens 7RQ0201-1DX00 is a relay socket for 4 changeover contacts (4CO) with an 8-pin relay connection, designed for 7 A applications and DIN rail mounting. Siemens' official SINOVA 7RQ documentation lists this exact article as the DIN rail mounting socket for 4 CO, 7 A plug-in relays.

The Siemens Industry Mall description additionally specifies panel mounting with screw terminals for this article. The current product data identifies it as an active product (PM300), with a quantity unit and packaging quantity of 1 piece and a minimum order quantity of 10 pieces.

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

Siemens 7RQ0201-1DX00 Relay Socket

The 7RQ0201-1DX00 belongs to the Siemens SINOVA 7RQ plug-in relay system. It provides the mechanical and electrical interface between a compatible 7RQ plug-in relay and the fixed control-panel wiring.

Its DIN rail mounting format makes it suitable for organized installation inside electrical control cabinets, while the screw-terminal connection supports conventional field wiring.

4 Changeover Contacts

The socket is designed for a compatible relay having 4 changeover contacts (4CO).

A changeover contact provides a common connection that switches between normally open and normally closed paths according to the relay state. Four changeover contacts allow multiple switching functions to be handled through one relay.

Typical applications include:

• Control-circuit switching

• Status indication

• Electrical interlocking

• Signal switching

• Auxiliary control

• Machine-control circuits

The actual application should remain within the ratings of the complete relay and connected circuit.

8-Pin Connection

The exact 7RQ0201-1DX00 uses an 8-pin interface for the compatible 4CO relay. Siemens' official documentation places it in the 4 CO, 7 A socket category.

Before installation, the relay pin arrangement should be checked against the socket to ensure correct mechanical and electrical compatibility.

7 A Rating

The socket is specified for the 4CO, 7 A relay category. Siemens' official 7RQ documentation confirms the 4 CO, 7 A configuration for this socket.

The complete switching capability should be evaluated using the relay's contact rating, connected load, switching category and circuit conditions rather than relying only on the socket rating.

DIN Rail Mounting

The 7RQ0201-1DX00 is designed for DIN rail mounting, making it suitable for standard industrial control cabinets.

DIN rail installation can provide:

• Organized component placement

• Faster panel assembly

• Convenient maintenance

• Standardized mounting

• Easy replacement

Siemens' official documentation specifically lists 7RQ0201-1DX00 as the DIN rail mounting version of the 4CO, 7 A socket.

Panel Mounting with Screw Terminals

Siemens' Industry Mall description specifies this article as DIN rail mounting, panel mounting, screw terminal.

The screw-terminal arrangement provides a conventional and service-friendly connection method for industrial control-panel wiring.

Relay Socket Function

The socket provides two primary functions:

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

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

Because the relay is plug-in, maintenance teams can replace the relay without removing the socket and disturbing the complete wiring arrangement.

Compatible Plug-In Relay

The 7RQ0201-1DX00 should be used with a compatible Siemens 7RQ plug-in relay matching the required:

• 4CO contact configuration

• 8-pin arrangement

• 7 A category

• Mechanical dimensions

• Coil requirements

Siemens' 7RQ brochure identifies the corresponding socket under the 4 CO, 7 A relay family.

The exact relay coil voltage must be selected separately according to the control circuit.

Industrial Control Applications

The 7RQ0201-1DX00 can be considered for compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control systems

• Relay interface circuits

• Control and signalling systems

• Process-control equipment

• Industrial machinery

• Switchboard auxiliary circuits

• Maintenance and replacement applications

Multiple Switching Functions

The 4CO configuration allows the compatible relay to provide four changeover switching functions.

Depending on the control design, these contacts may be used for:

• Multiple status signals

• Separate interlocking functions

• Auxiliary control circuits

• Alarm signalling

• Control-signal distribution

• Equipment monitoring

The actual circuit design should follow the relay's electrical ratings.

Difference from PCB-Mounted Socket

Siemens provides a separate PCB-mounted socket for the same 4CO, 7 A relay configuration:

7RQ0201-1DX00 – DIN rail mounting

7RQ0202-1DX00 – PCB mounting

Therefore, the correct article should be selected according to the required installation method.

Difference from 2CO Sockets

The Siemens 7RQ range also includes sockets for 2CO relays.

For example:

7RQ0201-1BX00 – 2CO, 6 A, DIN rail mounting

7RQ0211-1BX00 – 2CO, 10 A, DIN rail mounting

By comparison, 7RQ0201-1DX00 is the 4CO, 7 A DIN rail version.

This difference is important when selecting replacement sockets.

Replacement and Maintenance

The 7RQ0201-1DX00 can be used as a replacement for a compatible 7RQ relay socket in an existing control-panel installation.

Before ordering, verify:

• Relay article number

• 4CO contact configuration

• 8-pin connection

• 7 A category

• DIN rail/panel mounting requirement

• Screw-terminal arrangement

• Relay coil voltage

• Mechanical compatibility

Siemens SINOVA 7RQ Socket Range

The 7RQ family provides different socket configurations according to contact count, current and mounting method. Siemens' official documentation identifies:
