ABB CR-M Pluggable Interface Relays for PLC & Industrial Control Panels

ABB CR-M is a range of miniature pluggable interface relays used in PLC panels, machine control systems, process automation and general industrial control circuits. The relay works between the control side and field devices, providing electrical isolation and allowing a low-power control signal to switch another circuit.

The CR-M range is useful where more contacts are needed from one relay. Depending on the model, ABB offers 2 changeover contacts rated up to 12 A, 3 changeover contacts up to 10 A, or 4 changeover contacts up to 6 A.

A built-in test button makes commissioning and troubleshooting easier, while optional LED indication allows the relay operating status to be checked directly inside the panel. ABB also offers gold-plated contact versions for low-level and sensitive signal switching.

CR-M relays are available in a wide range of AC and DC coil voltages, making them suitable for both new panel-building projects and replacement requirements.

ABB CR-M LED & Gold Contact Versions

The CR-M range is not limited to the basic relay models.

ABB also offers versions with:

• Integrated LED indication
• Gold-plated contacts
• LED with gold-plated contacts
• Free-wheeling diode on selected DC versions
• Complete relay and socket combinations

A model such as CR-M024DC4LG combines a 24 V DC coil, four changeover contacts, LED indication and gold-plated contacts.

Gold-contact versions are mainly useful when the relay is switching small electronic signals where reliable operation at low current and voltage levels is important.

For normal control loads such as contactor coils or signalling circuits, the standard contact versions are generally the more common choice.

ABB CR-M Complete Relay Assemblies

ABB also offers CR-M as complete assembled interface-relay units.

These can include:

• CR-M relay
• Relay socket
• Relay holder
• Marker
• LED or protection module, depending on version

Complete assemblies are useful for panel builders who want one ready-to-install part instead of ordering the relay, socket and suppression module separately.

ABB offers standard and logical sockets along with screw and spring connection options.

Features

• 2, 3 or 4 changeover contacts: Allows several control circuits to be switched from one relay.
• Up to 12 A switching: The 2-contact versions handle higher currents than many compact interface relays.
• Wide coil-voltage range: Suitable for 24 V DC automation panels as well as 110 V DC, 230 V AC and other industrial control supplies.
• Built-in test button: The relay can be operated manually during commissioning and fault finding.
• Lockable test position: Useful when checking wiring or control sequences during panel testing.
• LED versions available: Gives quick visual confirmation when the coil is energised.
• Gold-contact options: Suitable for switching sensitive and low-level signals.
• Pluggable construction: A failed relay can be replaced without disconnecting all of the socket wiring.
• Multiple socket options: Standard and logical arrangements are available.
• Plug-in suppression modules: Diode, RC and varistor accessories can be selected according to the control circuit.
• Compact construction: Provides several relay contacts without taking excessive panel space.
• Suitable for international projects: Multiple AC and DC coil voltages make the same relay family useful across different control-system standards.

ABB CR-M for PLC Interface Applications

ABB CR-M relays are commonly installed between PLC outputs and field devices.

For example, a 24 V DC PLC output can energise a CR-M024DC2, CR-M024DC3 or CR-M024DC4 relay. The relay contacts can then be used to operate or signal other equipment without putting the field circuit directly onto the PLC output.

Typical loads include:

• Contactor coils
• Solenoid valves
• Motor control circuits
• Alarm circuits
• Indication lamps
• Interlocking circuits
• Control-panel signals
• Auxiliary circuits

The number of contacts can be selected according to the job. A 2 c/o relay may be enough for a simple PLC interface, while a 4 c/o CR-M relay is useful when one control signal has to operate several circuits.

Applications

ABB CR-M miniature relays are suitable for:

• PLC control panels
• Industrial automation systems
• MCC panels
• Machine control panels
• Process control systems
• OEM machinery
• Packaging machines
• Conveyor systems
• Material handling equipment
• Pump control panels
• HVAC automation
• Water and wastewater plants
• Manufacturing lines
• Factory automation
• Building automation systems
• Generator control panels
• Electrical distribution panels
• Control and signalling circuits
• Contact multiplication
• Signal isolation
• PLC output interfacing
  Sensor and actuator interface circuits

ABB CR-M024DC2, CR-M024DC3 & CR-M024DC4 24V DC Relays

For industrial automation projects using a 24 V DC control supply, three important CR-M models are:

CR-M024DC2 – 1SVR405611R1000
