Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2967675 be used as a direct replacement for the 2909521?

A: Yes. Both parts are identical in all critical electrical parameters (coil voltage, contact rating, switching voltage, timing characteristics), mechanical configuration (DIN rail mounting, screw terminals), and compliance certifications (RoHS). Direct substitution is supported without circuit modification.

Q: Are there any differences in the relay's switching performance between these two part numbers?

A: No. Both relays have identical operate time (7 ms) and release time (10 ms), ensuring equivalent switching performance in control circuits.

Q: What is the significance of the different base product numbers (29095 vs. 29676)?

A: The base product numbers indicate different manufacturing batches or revisions within the PLC-RSC series. However, all specified electrical and mechanical parameters remain identical, confirming full interchangeability.

Q: Are both parts suitable for 230VAC and 230VDC applications?

A: Yes. Both relays are rated for 230VAC/DC coil voltage and support switching of loads up to 250VAC or 250VDC maximum, making them suitable for both AC and DC control circuits.

Q: What is the maximum load current these relays can switch?

A: Both relays are rated for 10A contact current at the specified switching voltages (250VAC, 250VDC - Max).

Q: Are these relays suitable for outdoor or harsh environment applications?

A: Both relays operate within the temperature range of -40°C to 55°C. Specific environmental protection requirements (moisture, vibration, chemical exposure) should be evaluated based on the application's environmental classification and the relay's seal rating specifications.
