Safety Contactor Relay · 24V DC Coil · 2NO + 2NC 4-Pole · Mechanically Linked Contacts · Noark Electric EX9RCA22DBS
What this product is for
The Noark Electric EX9RCA22DBS is a safety contactor relay for machine safety and control circuits. It is designed for fail-safe switching in safety-related parts of control systems where mechanically linked contacts are required for monitoring and feedback.
Use for
- Safety relay and safety controller output circuits
- Machine stop circuits and feedback monitoring
- SRP/CS applications requiring force-guided or mechanically linked contacts
- Industrial control panels using a 24V DC control voltage
Avoid for
- General-purpose switching where a safety-rated relay is not required
- Applications where coil voltage does not match 24V DC
- Installations requiring confirmed load ratings not provided in the source material
Best for
Best for OEM panels, machinery safety circuits, and industrial automation systems where electricians and panel builders need a compact safety control relay with 2 normally open and 2 normally closed contacts in one 4-pole device.
Installed in
Typically installed in industrial control panels, machine control cabinets, production equipment, and automation systems in manufacturing and processing environments across Canada. The relay is described as mounting on 35 mm DIN rail or panel, depending on the installation arrangement.
Why this product exists
This relay exists to provide monitored switching in safety circuits. Its mechanically linked contact construction helps the control system detect contact state more reliably than a standard control relay, which is important in safety feedback loops and machine safeguarding schemes.
Compared with similar products
Compared with a standard control relay, this safety contactor relay is intended for safety function applications and uses mechanically linked contacts. Compared with larger safety contactors, this 4-pole relay format is commonly selected when the control design needs multiple auxiliary-style safety contacts rather than higher power switching. As a rule of thumb, always confirm coil voltage, contact arrangement, and the required safety architecture before ordering.
