Product Description

Siemens 7RQ0201-1AX00 Relay Socket – 1 Changeover Contact, 5-Pin, 10A, DIN Rail Mounting

The Siemens 7RQ0201-1AX00 is a DIN rail-mounted relay socket for compatible Siemens 7RQ plug-in relays with 1 changeover contact (1CO). It has a 5-pin connection, belongs to the 10 A socket category, and uses screw-terminal connections for panel wiring. Siemens identifies this exact article as the DIN rail mounting socket for 1 CO, 10 A relays.

The product is an accessory/socket rather than the relay itself. It provides the mechanical mounting and electrical connection between a compatible plug-in relay and the fixed control-panel wiring.

Siemens 7RQ0201-1AX00 Relay Socket

The 7RQ0201-1AX00 belongs to the SINOVA 7RQ plug-in relay accessory range. It is designed for installation on a standard DIN rail and provides a convenient interface for a compatible 1CO relay.

Siemens product data identifies the article as PM300: Active Product, with a quantity unit of 1 piece, packaging quantity of 1, and minimum order quantity of 10 pieces. The listed net weight is 0.024 kg.

1 Changeover Contact

The socket is intended for a relay with 1 changeover contact, commonly called 1CO or 1 C/O.

A changeover contact provides:

• Common contact

• Normally Open (NO) contact

• Normally Closed (NC) contact

This allows one relay to switch a circuit between two output paths according to the relay's operating state.

Typical applications include:

• Control-circuit switching

• Status indication

• Signal switching

• Interlocking

• Auxiliary control

• Machine-control circuits

The actual application depends on the compatible relay and connected load.

5-Pin Connection

The 7RQ0201-1AX00 uses a 5-pin relay interface. Siemens' 7RQ documentation identifies this article under the 1CO socket category, with the corresponding 1CO relay using the 5-pin arrangement.

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

10 A Rating

The exact socket is specified for the 1CO, 10 A relay category. Siemens documentation lists 7RQ0201-1AX00 as the DIN rail socket for the 1 CO, 10 A configuration.

The actual load capability must be evaluated using the complete relay, socket and circuit ratings. The connected load should not exceed the applicable electrical ratings.

DIN Rail Mounting

The 7RQ0201-1AX00 is specifically designed for DIN rail mounting. This makes it suitable for standard industrial control cabinets and electrical panels.

DIN rail installation provides:

• Standardized mounting

• Organized panel layout

• Convenient installation

• Easy maintenance

• Simple relay replacement

Siemens' official 7RQ brochure directly identifies 7RQ0201-1AX00 as the DIN rail mounting socket for 1CO relays.

Panel Mounting and Screw Terminal Connection

The exact product description specifies DIN rail mounting, panel mounting and screw-terminal connection.

The screw-terminal arrangement provides a conventional and service-friendly wiring method for industrial control panels, allowing fixed wiring to remain connected while the plug-in relay can be replaced.

Relay Socket Function

The socket performs two main functions:

Mechanical support: It holds the compatible plug-in relay securely.

Electrical interface: It connects the relay terminals with the fixed control-panel wiring.

This socketed arrangement can simplify maintenance because the relay can be removed and replaced without removing the complete socket wiring.

Compatible Plug-In Relay

The 7RQ0201-1AX00 should be paired with a compatible Siemens 7RQ 1CO plug-in relay matching the required:

• 1CO contact configuration

• 5-pin arrangement

• 10 A category

• Coil voltage

• Mechanical dimensions

Siemens' 7RQ range includes several coil-voltage variants, so the exact relay should be selected according to the control circuit requirements.

Industrial Control Applications

The 7RQ0201-1AX00 can be used in compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control systems

• Relay interface circuits

• Process-control equipment

• Signal switching

• Status indication

• Auxiliary control circuits

• Industrial machinery

• Maintenance and replacement applications

Its compact DIN rail format makes it suitable for conventional industrial panel layouts.

Compact Relay Interface

Using a dedicated relay socket can simplify panel construction and maintenance.

The 7RQ0201-1AX00 provides:

• Organized relay mounting

• Fixed screw-terminal wiring

• Plug-in relay replacement

• Reduced wiring disturbance during servicing

• Standardized mounting on DIN rail

This is useful for control-panel and machine-building applications.

Difference from PCB-Mounted Socket

Siemens provides a separate PCB-mounted socket for the same 1CO, 10 A relay category:

7RQ0201-1AX00 → DIN rail mounting

7RQ0202-1AX00 → PCB mounting

The correct article should therefore be selected according to whether the installation requires DIN rail or PCB mounting.

Difference from 2CO, 6A Socket

The 7RQ0201-1BX00 is a 2CO, 6 A DIN rail socket, while 7RQ0201-1AX00 is a 1CO, 10 A DIN rail socket. Siemens lists these as separate articles within the 7RQ socket range.

This difference is important when selecting a replacement socket.

Difference from 2CO, 10A Socket

The 7RQ0211-1BX00 is the 2CO, 10 A DIN rail socket, whereas 7RQ0201-1AX00 is the 1CO, 10 A version.

The required contact configuration should therefore be verified before procurement.

The dimensions and weight are from Siemens' official 7RQ documentation, while the current Industry Mall product data confirms packaging, MOQ, lifecycle and origin.
