Product Description

Siemens 7RQ0201-1BX00 Relay Socket – 2 Changeover Contacts, 8-Pin, 6A, DIN Rail Mounting

The Siemens 7RQ0201-1BX00 is a DIN rail-mounted relay socket designed for compatible 2 changeover contact (2CO) plug-in relays. It has an 8-pin relay interface, belongs to the 6 A relay category, and uses screw-terminal connections for panel wiring. Siemens' official SINOVA 7RQ documentation identifies 7RQ0201-1BX00 as the DIN rail mounting socket for 2 CO, 6 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 7RQ0201-1BX00 Relay Socket

The 7RQ0201-1BX00 belongs to the Siemens SINOVA 7RQ plug-in relay system and provides the mechanical and electrical interface between a compatible plug-in relay and the fixed panel wiring.

Its DIN rail mounting design is suitable for organized installation in industrial control panels, while the screw-terminal connection provides a conventional method for connecting the relay circuit.

2 Changeover Contacts

The socket is designed for a compatible relay with 2 changeover contacts (2CO).

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

The two changeover contacts can support multiple control functions such as:

• Control-circuit switching

• Status indication

• Signal switching

• Electrical interlocking

• Auxiliary control

• Machine-control circuits

The actual application depends on the relay installed and the connected electrical circuit.

8-Pin Connection

The 7RQ0201-1BX00 uses an 8-pin relay connection for the corresponding 2CO relay configuration.

The relay must have the correct 8-pin mechanical and electrical arrangement to fit the socket. Pin compatibility should be verified before installation or replacement.

6 A Rating

The exact article is specified for the 2CO, 6 A relay category.

The 6 A rating should be considered together with the relay's actual contact rating, connected load, switching category and operating conditions. The complete relay-and-socket assembly must be selected according to the electrical application.

DIN Rail Mounting

A key feature of the 7RQ0201-1BX00 is its DIN rail mounting arrangement.

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

• Standardized mounting

• Organized panel layout

• Faster installation

• Easy maintenance

• Convenient replacement

The socket can be installed alongside other DIN rail-mounted electrical components such as terminal blocks, control relays and protection devices.

Panel Mounting and Screw Terminals

The product description specifies panel mounting with screw-terminal connection.

The screw terminals provide a practical and service-friendly wiring method for industrial control panels. They allow fixed circuit wiring to remain connected while the plug-in relay itself can be removed for replacement.

Relay Socket Function

The socket performs two main functions:

Mechanical support: Holds the compatible relay in its correct position.

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

This plug-in arrangement can reduce maintenance time because relay replacement does not normally require disconnecting each individual field wire from the socket.

Compatible Plug-In Relay

The 7RQ0201-1BX00 should be used with a compatible Siemens 7RQ relay having:

• 2CO contact configuration

• 8-pin arrangement

• 6 A rating category

• Compatible coil voltage

• Matching mechanical dimensions

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

Industrial Control Applications

The 7RQ0201-1BX00 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

• Industrial machinery

• Maintenance and replacement applications

Its DIN rail format is particularly suitable for conventional industrial panel layouts.

Multiple Switching Functions

The 2CO configuration allows the compatible relay to provide two independent changeover switching functions.

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

• Multiple status signals

• Alarm indication

• Control-signal switching

• Interlocking

• Auxiliary switching

• Equipment monitoring

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

Difference from 7RQ0211-1BX00

Both articles have 2 changeover contacts, 8-pin connection and DIN rail mounting, but their current categories differ:

7RQ0201-1BX00: 2CO, 6 A

7RQ0211-1BX00: 2CO, 10 A

This distinction is important when selecting a replacement socket.

Difference from 7RQ0202-1BX00

The 7RQ0202-1BX00 is the PCB-mounted socket for the 2CO, 6 A relay configuration, while 7RQ0201-1BX00 is the DIN rail/panel-mounted version.

Therefore:

7RQ0201-1BX00 → DIN rail / panel mounting

7RQ0202-1BX00 → PCB mounting

Difference from 7RQ0212-1BX00

The 7RQ0212-1BX00 is the PCB-mounted 2CO, 10 A socket, while 7RQ0201-1BX00 is the DIN rail/panel-mounted 2CO, 6 A version.

Selecting the correct current category and mounting method is important for replacement applications.

Replacement and Maintenance

The 7RQ0201-1BX00 can be used where an existing compatible relay socket needs replacement in a DIN rail-mounted control panel.

Before ordering, verify:

• Existing relay article

• 2CO contact configuration

• 8-pin arrangement

• 6 A category

• DIN rail mounting requirement

• Screw-terminal arrangement

• Relay coil voltage

• Mechanical compatibility
