Control Relays

About Industrial Control Relays

Control relays are widely used in electrical panels, machinery and automation systems where switching, interlocking, signalling or electrical isolation is required. They are commonly installed between PLC outputs, sensors, contactors, motor starters and other control devices to manage auxiliary circuits without placing the complete load on the controlling device.

ARP IMPEX supplies industrial control relays for new panel building, OEM machinery, plant maintenance, shutdown requirements and replacement of existing relay models. We handle enquiries where the buyer already has a complete relay part number as well as requirements where the relay needs to be identified from the coil voltage, contact arrangement, socket details or existing nameplate.

Buyers looking for a control relay supplier in India, industrial control relay exporter, or a source for specific ABB, Schneider Electric, Siemens, Legrand or other control relay models can send us the complete ordering information for quotation.

Control Relays for Industrial Panels & Automation Systems

Control relays are used across simple auxiliary switching circuits as well as larger automation and electrical control systems. The correct relay depends on the operating voltage, number and type of contacts, switching duty, mounting method and the equipment connected to the relay.

Typical requirements we receive include control relays for:

• MCC and PCC panels
• PLC interface and output circuits
• Motor starter and interlocking circuits
• Pump and compressor control panels
• Conveyor and material handling systems
• HVAC and building control panels
• Packaging and production machinery
• Process automation systems
• Machine tools and OEM equipment
• Switchgear and distribution panels
• Industrial signalling and alarm circuits
• Plant maintenance and replacement requirements

Control Relay Selection – What Buyers Should Specify

A control relay should not normally be selected only by physical appearance or contact current. Two relays that look similar may have different coil voltages, terminal arrangements, contact configurations or mounting requirements.

For a faster quotation, send us the manufacturer name, complete model or ordering code, coil voltage, contact arrangement, quantity and delivery destination.

Depending on the application, it may also be useful to confirm whether the requirement is for AC or DC coil operation, the number of NO and NC contacts, relay/socket combination, DIN rail or panel mounting, indication requirements and any accessories used with the existing relay.

ABB, Schneider Electric, Siemens, Legrand & Other Control Relays

ARP IMPEX handles control relay requirements from established industrial electrical manufacturers for electrical panels, machinery, OEM systems and automation applications.

Our enquiries commonly involve ABB and Schneider Electric control relays, and we can also check Siemens and other industrial relay requirements against the complete model or ordering code. Depending on the product family, control relay requirements may include compact auxiliary relays, plug-in relays, interface arrangements, control circuit relays and related sockets or accessories.

If you are sourcing an ABB control relay supplier in India, Schneider Electric control relay exporter, Siemens industrial control relay supplier, or need an older control relay for maintenance, send us the exact model number rather than only the general relay description. This helps us check the requirement more accurately.

Control Relay Brands We Supply

Schneider Electric Control Relays

Schneider Electric offers a broad range of control relays for monitoring and controlling electrical conditions in machinery, control panels and automation systems. The Harmony and Zelio ranges cover applications such as voltage, current, phase, frequency, speed and temperature monitoring, with conventional and electronic options available for different control requirements. ARP IMPEX handles enquiries for Schneider Electric control relays against complete model or ordering codes for new installations, maintenance and replacement requirements.

Siemens Control & Auxiliary Relays

Siemens SIRIUS relays are widely used in industrial control circuits for switching, signalling, interlocking and electrical isolation. The range includes 3RH2 contactor relays for auxiliary circuits and 3RQ4 coupling relays for interfacing controllers with field-level equipment. Buyers looking for Siemens control relays, auxiliary relays or coupling relays can send the complete Siemens ordering code, coil voltage, contact arrangement and required quantity for quotation.

Legrand Control Relays

Legrand supplies CTX³ control relays for auxiliary and control-circuit switching in industrial and commercial electrical installations. Available configurations include different NO and NC contact arrangements and coil voltages, with options for DIN-rail or plate mounting depending on the model. ARP IMPEX can handle Legrand CTX³ control relay requirements for panel building, machinery, maintenance and replacement applications against the complete Legrand reference number.

ABB Relays for Control & Interface Applications

ABB offers relay products for control-circuit interfacing as well as protection and control applications. Its CR-M, CR-S and related interface relay ranges are used for electrical isolation, signal amplification and signal matching between PLCs or other electronic controls and field devices. ABB’s Relion range, on the other hand, combines protection, monitoring and control functions for power distribution systems and should be treated separately from conventional low-voltage control relays.

Control Relays for Maintenance & Replacement Requirements

A large part of the industrial relay market involves replacement rather than new installation.

Control relays used in machinery and electrical panels may require replacement because of damaged contacts, failed coils, ageing equipment, panel refurbishment or changes in the control system. In some cases, the original relay may have been installed many years ago and the ordering code may no longer be clearly readable.

For such requirements, buyers can share the existing relay model, nameplate photograph, coil voltage, contact configuration and socket details. If a datasheet or panel drawing is available, that can also help when checking an older or difficult-to-identify control relay.

We handle requirements ranging from a single replacement control relay to maintenance quantities and larger OEM or project requirements, depending on the model and availability.
