ABB R600 Interface Relays for PLC & Industrial Control Panels

ABB R600 is a compact range of boxed interface relays used in PLC panels, machine control, industrial automation and general control circuits. These relays are used between the control system and field equipment for signal isolation, switching and contact multiplication.

Unlike conventional plug-in interface relays, the relay element in the R600 series is built directly into the housing. This gives the unit a compact construction and makes it suitable for control panels and machinery where vibration resistance and secure mounting are important.

The ABB R600 range includes 1 NO, 1 NC, 1 changeover and 2 changeover contact versions, with different AC, DC and AC/DC control voltages. Screw and spring terminal models are available, along with gold-plated contact versions for low-level signal switching.

For an ABB R600 interface relay quotation, buyers can share the exact model number, input voltage, contact configuration and quantity.

ABB R600 Relay Models

The R600 family covers several relay configurations for different control requirements.

ABB RB101

RB101 models are available with 1 normally closed contact and are used for simple control and signalling circuits.

ABB RB111

RB111 relays provide 1 normally open contact and are suitable where a control signal needs to switch a single external circuit.

Common voltage options include 24 V AC/DC, 115 V AC/DC and 230 V AC/DC.

ABB RB121

RB121 is one of the commonly used R600 versions and provides 1 changeover contact.

Popular models include:

• RB121-12VDC
• RB121-24VDC
• RB121-24VUC
• RB121-48-60VUC
• RB121-115VUC
• RB121-230VUC
• RB121-60-230VUC

The RB121-24VDC is particularly suitable for PLC and automation panels using a 24 V DC control supply.

ABB RB121G

RB121G versions use gold-plated contacts and are intended for switching low-current or sensitive electronic signals.

Available versions include 12 V DC, 24 V DC, 24 V AC/DC, 48–60 V, 115 V and 230 V control options.

ABB RB122

RB122 versions provide 2 changeover contacts where one input signal needs to switch two separate circuits.
These models are suitable for applications requiring additional contact multiplication from a single interface relay.

ABB RBR Series

RBR versions are supplied with spring terminals, while the RB series generally uses screw terminals.

The electrical function remains similar, but the connection style allows panel builders to choose the wiring method that suits their panel design.

ABB R600 Relays for PLC Interface

R600 relays are commonly installed between PLC outputs and field devices. A 24 V DC PLC output can operate an R600 relay, while the relay contact switches a separate field or control circuit.

This arrangement is commonly used for:

• Contactor coils
• Solenoid valves
• Alarm circuits
• Pilot lamps
• Interlocks
• Auxiliary control circuits

The relay provides a simple way to isolate the PLC from the connected load while providing an independent switching contact.

ABB R600 Optocouplers

The R600 family also includes boxed optocoupler versions for applications where solid-state switching is preferred.

Options are available with:

• Transistor output
• MOSFET output
• Triac output
• Screw terminals
• Spring terminals

These are generally used where faster or frequent switching is required without using a mechanical relay contact.

Choosing the Correct ABB R600 Relay

When requesting a quotation, share:

• Complete ABB model number
• ABB order code
• Input/coil voltage
• Required contact arrangement
• Standard or gold-plated contacts
• Screw or spring terminals
• Relay or optocoupler requirement
• Quantity
