ABB CR-S Slim Interface Relays for PLC & Control Panels
ABB CR-S is a compact range of pluggable interface relays and optocouplers used between PLC outputs, control systems, sensors and field equipment. The slim construction makes the CR-S range a good choice for control panels where a large number of interface relays have to be installed, but DIN rail space is limited.
The standard CR-S relay provides one changeover contact and can switch loads up to 6 A at 250 V AC. Different coil voltages are available for common industrial control circuits, and gold-plated contact versions are offered for low-level signals.
ABB also offers complete CR-S interface relay assemblies with relay, socket and marker. Screw and spring terminal versions are available, which makes the range useful for new control-panel projects as well as replacement of existing ABB interface relays.
For requirements for an ABB CR-S interface relay supplier in India, ABB 24V DC slim relay, CR-S relay with socket, PLC interface relay or ABB CR-S export supply, buyers can share the complete model or ABB order code, coil voltage and quantity for quotation.
ABB CR-S Relay Models

These versions are generally used for low-current signal switching rather than higher-load control applications.
ABB CR-S Optocouplers
The CR-S family also includes solid-state optocoupler versions for applications where electrical isolation is required without a mechanical relay contact.
Available models include:
CR-S024VDC1TRA – 1SVR405510R3050

ABB CR-S Relay for PLC Interface Applications
One of the common applications for CR-S is between a PLC and field equipment.
A PLC output normally handles a relatively small control signal. The CR-S interface relay provides electrical isolation between the PLC and the connected load while allowing the relay contact to switch another control circuit.
A 24 V DC ABB CR-S PLC interface relay can therefore be used for switching devices such as:
- Contactors
- Solenoid valves
- Indication circuits
- Small control loads
- Interposing control circuits
- Alarm circuits
The slim construction becomes particularly useful when dozens of PLC outputs have to be interfaced inside the same cabinet.
