Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2912280 is determined by strict equivalence across the following critical parameters:

• Contact configuration: SPDT (1 Form C)
• Coil voltage: 24VAC/DC
• Contact current rating: 10 A
• Switching voltage capability: 250VAC, 250VDC maximum
• Mounting interface: DIN rail
• Coil type: Non latching
• Contact material: Silver Nickel (AgNi)
• Coil current draw: 17.5 mA
• Timing characteristics: 8 ms operate time, 10 ms release time
• Operating temperature range: -40°C ~ 60°C
• Coil resistance: 1.37 kOhms

The Phoenix Contact 2900293 meets all these critical parameters and is classified as a direct substitute for the obsolete 2912280 model.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900293 is the direct substitute for the obsolete 2912280. Both relays maintain identical electrical and mechanical specifications across all critical parameters. The 2900293 offers the advantage of active product status, ensuring continued availability and support. Additionally, the 2900293 carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements for new designs and system upgrades. The inclusion of a socket with the 2900293 provides enhanced modularity compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2900293 directly replace the 2912280 in existing installations?

A: Yes. The 2900293 maintains identical coil voltage (24VAC/DC), contact configuration (SPDT), current rating (10A), switching voltage (250VAC/250VDC), timing characteristics (8ms operate, 10ms release), and operating temperature range (-40°C to 60°C). DIN rail mounting is identical on both models.

Q: What is the primary difference between these two relays?

A: The 2912280 is obsolete, while the 2900293 is an active product. The 2900293 includes a socket as standard and carries updated ROHS3 compliance and REACH affected status.

Q: Are the coil specifications identical between the two models?

A: Yes. Both relays have 24VAC/DC coil voltage, 17.5 mA coil current, 1.37 kOhms coil resistance, and non-latching coil type.

Q: Does the included socket on the 2900293 affect compatibility?

A: No. The socket is an additional feature that enhances modularity. The relay maintains the same DIN rail mounting interface and spring terminal connections as the original 2912280.

Q: Are there any compliance differences between the two parts?

A: The 2912280 is RoHS Compliant. The 2900293 is ROHS3 Compliant and REACH Affected, reflecting current regulatory standards.
