Product Description

Siemens 7RQ0100-0DA00 Plug-In Relay – 4CO, 14-Pin, 5A, 6V DC

The Siemens 7RQ0100-0DA00 is a SINOVA 7RQ plug-in relay with 4 changeover contacts (4CO), a 14-pin configuration, and a 5 A contact rating. The exact article is the 6 V DC version and includes an LED indicator across the coil. Siemens' official 7RQ documentation identifies the 4CO, 5 A relay family as 14-pin, with 7RQ0100-0DA0 listed for 6 V DC control supply.

Siemens 7RQ0100-0DA00 Plug-In Relay

The 7RQ0100-0DA00 belongs to the Siemens SINOVA 7RQ plug-in relay family for industrial control, switching, signalling and auxiliary circuit applications.

It provides four changeover contacts in one compact plug-in relay, allowing several independent switching functions to be handled through a single control signal. Siemens places this article in the 4CO, 5 A, 14-pin DC relay family.

6 V DC Control Supply

The defining specification of 7RQ0100-0DA00 is its 6 V DC control supply.

Siemens lists the DC control-voltage variants of the 4CO, 5 A, 14-pin family as:

• 6 V DC – 7RQ0100-0DA0

• 12 V DC – 7RQ0100-0DB00

• 24 V DC – 7RQ0100-0DC00

• 48 V DC – 7RQ0100-0DD00

• 110 V DC – 7RQ0100-0DE00

The relay coil should therefore be supplied with the specified 6 V DC control voltage.

4 Changeover Contacts

The relay provides 4 changeover contacts (4CO).

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

The four contacts can support multiple control functions from one relay, including:

• Control-circuit switching

• Auxiliary switching

• Status indication

• Signal transfer

• Electrical interlocking

• Alarm circuits

• Machine-control circuits

The connected load must remain within the applicable relay contact specifications.

14-Pin Configuration

The correct Siemens configuration for 7RQ0100-0DA00 is 14 pins. Siemens' official product documentation identifies the complete 4CO, 5 A relay family as 14-pin.

This is important when selecting the appropriate relay socket. The socket and relay must have matching mechanical and electrical configurations.

5 A Contact Rating

The 7RQ0100-0DA00 belongs to the 4CO, 5 A relay category. Siemens' official selection table specifies 4 CO, 5 A, 14 pin for this relay family.

The actual switching load should be evaluated according to the load type, operating voltage, switching category and complete circuit requirements.

LED Indicator Across Coil

The relay includes an LED indicator across the coil. Siemens lists this as a standard feature of the 4CO, 5 A relay family.

The LED provides a convenient visual indication when the relay coil is energized and can assist with:

• Panel inspection

• Maintenance

• Troubleshooting

• Relay-status identification

Plug-In Construction

The 7RQ0100-0DA00 uses a plug-in relay design, allowing it to be fitted into a compatible Siemens relay socket.

This construction can simplify:

• Relay replacement

• Preventive maintenance

• Panel servicing

• Troubleshooting

• Spare-part replacement

The socket can remain connected to the fixed control wiring while the relay itself is removed.

Compatible Relay Sockets

For the Siemens 4CO, 5 A relay family, the corresponding mounting sockets are listed separately. Siemens identifies:

7RQ0201-1DX00 – DIN rail mounting socket

7RQ0202-1DX00 – PCB mounting socket

The appropriate socket should be selected according to the installation method and the complete relay assembly.

Industrial Control Applications

The 7RQ0100-0DA00 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 depends on the relay circuit and connected load.

Multiple Switching Functions

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

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

• Multiple status signals

• Electrical interlocking

• Alarm indication

• Auxiliary control

• Signal switching

• Equipment monitoring

• Control-sequence functions

The exact contact utilization should follow the electrical design and relay ratings.

Difference from 12 V DC Version

The 7RQ0100-0DB00 is the 12 V DC version, while 7RQ0100-0DA0 is the 6 V DC version.

Both belong to the same 4CO, 5 A, 14-pin DC relay family, but their coil voltages are different.

Difference from 24 V DC Version

The 7RQ0100-0DC00 is the 24 V DC version, whereas 7RQ0100-0DA0 is the 6 V DC version.

The control supply must therefore match the exact relay article.

Difference from 6 V AC Version

Siemens also lists a separate 6 V AC article, 7RQ0100-0DK00, for the same 4CO, 5 A relay family. The product in this page is 7RQ0100-0DA0, which is specifically the 6 V DC version.

The AC and DC versions are separate articles and should not be treated as interchangeable.

Replacement and Maintenance

The 7RQ0100-0DA00 can be used where an existing installation requires a 4CO, 14-pin, 5 A, 6 V DC plug-in relay.

Before ordering, verify:

• Exact relay article

• Control-supply voltage

• AC or DC operation

• 4CO contact configuration

• 14-pin arrangement

• Contact rating

• Compatible socket

• Existing control circuit

This is especially important for low-voltage relay coils such as the 6 V DC version.
