Product Description

Siemens 7RQ0100-0BM10 Plug-In Relay – 2CO, 8-Pin, 6A, 24V AC

The Siemens 7RQ0100-0BM10 is a SINOVA 7RQ plug-in relay with 2 changeover contacts (2CO), an 8-pin configuration, and a 6 A contact rating. The exact article is designed for a 24 V AC control supply and is listed by Siemens in the 2CO, 6 A, 8-pin AC relay family. Siemens specifies mechanical flag and LED indicator across the coil as standard features for this relay family.

The relay is intended for compatible industrial control, switching, signalling, auxiliary-circuit and relay-interface applications.

Siemens 7RQ0100-0BM10 Plug-In Relay

The 7RQ0100-0BM10 belongs to the Siemens SINOVA 7RQ plug-in relay range. Its plug-in construction allows the relay to be fitted into a compatible relay socket, making relay replacement and maintenance more convenient.

The relay provides two changeover contacts, allowing two independent switching functions to be handled through a single relay coil. Siemens identifies 7RQ0100-0BM10 specifically as the 24 V AC article within the 2CO, 6 A, 8-pin family.

24 V AC Control Supply

The defining characteristic of 7RQ0100-0BM10 is its 24 V AC control supply.

Siemens lists the AC variants of the 2CO, 6 A, 8-pin family as:

• 6 V AC – 7RQ0100-0BK10

• 12 V AC – 7RQ0100-0BL10

• 24 V AC – 7RQ0100-0BM10

• 48 V AC – 7RQ0100-0BN10

• 110 V AC – 7RQ0100-0BP10

• 115 V AC – 7RQ0100-0BQ10

• 230 V AC – 7RQ0100-0BR10

The relay coil should be connected to the specified 24 V AC control circuit.

2 Changeover Contacts

The relay provides 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.

This configuration can be used for:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Signal transfer

• Electrical interlocking

• Alarm circuits

• Machine-control circuits

The connected load should remain within the applicable relay-contact ratings.

8-Pin Plug-In Configuration

The 7RQ0100-0BM10 uses an 8-pin plug-in configuration. Siemens identifies the 2CO, 6 A relay family as an 8-pin design.

The relay should be installed only in a compatible socket with the corresponding mechanical and electrical configuration.

For this 2CO, 6 A family, Siemens lists:

7RQ0201-1BX00 – DIN rail mounting socket

7RQ0202-1BX00 – PCB mounting socket

6 A Contact Rating

The exact 7RQ0100-0BM10 belongs to the 2CO, 6 A relay category.

The actual switching application should be selected according to the connected load, operating voltage, switching category and complete circuit requirements rather than relying only on the nominal current value.

Mechanical Flag and LED Indicator

Siemens specifies mechanical flag and LED indicator across the coil as standard features for this 2CO, 6 A relay family.

These features can assist during:

• Panel inspection

• Relay-status identification

• Troubleshooting

• Preventive maintenance

• Control-circuit checking

The LED provides a visual indication of coil energization, while the mechanical flag provides an additional visible indication of relay operating status.

Plug-In Construction

The relay uses a plug-in construction, allowing it to be inserted into a compatible Siemens relay socket.

This arrangement supports:

• Easy relay replacement

• Reduced maintenance effort

• Convenient servicing

• Simple troubleshooting

• Reusable socket wiring

The socket can remain connected to the control circuit while the relay is replaced separately.

Compatible Relay Sockets

For the 2CO, 6 A, 8-pin relay family, Siemens identifies:

7RQ0201-1BX00 – DIN rail mounting socket

7RQ0202-1BX00 – PCB mounting socket

The appropriate socket should be selected according to the actual installation method.

Industrial Control Applications

The 7RQ0100-0BM10 can be considered for compatible applications such as:

• Industrial control panels

• Electrical cabinets

• Machine-control systems

• Process-control circuits

• Relay interface systems

• Equipment signalling

• Alarm circuits

• Status indication

• Auxiliary switching

• Industrial machinery

• Maintenance and replacement applications

The final application should be based on the complete control-circuit design.

Control and Interlocking Applications

The two changeover contacts allow one relay to control multiple electrical paths.

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

• Electrical interlocking

• Equipment status feedback

• Alarm indication

• Auxiliary control

• Signal switching

• Control-sequence functions

• Process-status indication

The exact use of the contacts should follow the relay specifications and circuit design.

Difference from 10 A, 2CO Relay

The 7RQ0110-0BR00 is a 2CO, 8-pin, 10 A, 230 V AC relay, whereas 7RQ0100-0BM10 is a 2CO, 8-pin, 6 A, 24 V AC relay.

These articles differ in both contact-rating category and control voltage, so they should not be treated as interchangeable.

Difference from 230 V AC Version

The 7RQ0100-0BR10 is the 230 V AC version of the same 2CO, 6 A, 8-pin AC relay family, while 7RQ0100-0BM10 is the 24 V AC version.

Therefore:

7RQ0100-0BM10 → 24 V AC

7RQ0100-0BR10 → 230 V AC

The control voltage must match the relay article.

Difference from 24 V DC Version

The 7RQ0100-0BC00 is the 24 V DC version, while 7RQ0100-0BM10 is the 24 V AC version.

Although both use a nominal 24 V control voltage, they are different relay articles and the control supply must match the correct AC or DC coil type.

Difference from 48 V AC Version

The 7RQ0100-0BN10 is the 48 V AC version, while 7RQ0100-0BM10 is the 24 V AC version of the same relay family.

Replacement and Maintenance

The 7RQ0100-0BM10 can be used as a replacement where an existing installation requires a 2CO, 8-pin, 6 A, 24 V AC plug-in relay.

Before ordering, verify:

• Exact relay article

• Control-supply voltage

• AC or DC requirement

• 2CO contact configuration

• 8-pin arrangement

• 6 A rating

• Compatible relay socket

• Existing control-circuit requirements

This is especially important when replacing a visually similar 24 V DC or other-voltage relay.
