Phoenix Contact 2834614 General Purpose Relay DPDT 24VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834614 is a general purpose relay with DPDT (Double Pole Double Throw) contact configuration, rated for 8A at 24VAC coil voltage. This relay features a DIN rail mounting design with spring terminal connections, lighted indicator, and varistor protection. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834614 is constrained by the following critical parameters that must remain consistent:

• Contact Configuration: DPDT (2 Form C) - mandatory for equivalent switching capability
• Coil Voltage: 24VAC - required for direct integration into existing control circuits
• Mounting Type: DIN Rail - necessary for panel integration compatibility
• Termination Style: Spring Terminal - required for connection compatibility
• Coil Type: Non Latching - functional requirement for continuous energization operation

The Phoenix Contact 2903329 qualifies as a substitute based on matching these core parameters. However, the 2903329 operates at a reduced contact current rating of 50 mA compared to the 8A rating of the 2834614. This substitution is valid only for applications where the load current does not exceed 50 mA.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903329 is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for the obsolete 2834614. Selection of the 2903329 as a substitute requires verification that the application load current does not exceed 50 mA. The 2903329 operates within a narrower temperature range (-40°C ~ 50°C versus -25°C ~ 60°C) and has reduced maximum switching voltage ratings (30VAC/36VDC versus 250VAC/250VDC). The release time is extended to 20 ms compared to 14 ms for the original part. These differences must be evaluated against specific application requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 2903329 directly replace the 2834614 in all applications?

A: No. The 2903329 has a maximum contact current rating of 50 mA, while the 2834614 is rated for 8A. Direct substitution is only valid for applications where the load current does not exceed 50 mA.

Q: What are the key differences in electrical ratings?

A: The 2903329 has lower maximum switching voltage ratings (30VAC/36VDC) compared to the 2834614 (250VAC/250VDC). The 2903329 also has a longer release time of 20 ms versus 14 ms for the original part.

Q: Are both relays compatible with DIN rail mounting?

A: Yes. Both the 2834614 and 2903329 use DIN rail mounting with spring terminal connections, ensuring mechanical compatibility in panel installations.

Q: What is the operating temperature difference?

A: The 2834614 operates from -25°C to 60°C, while the 2903329 operates from -40°C to 50°C. Applications requiring operation above 50°C cannot use the 2903329.

Q: Do both relays have the same coil voltage?

A: Yes. Both relays operate on 24VAC coil voltage and are compatible with identical control circuits.

Q: What is the contact configuration for both parts?

A: Both relays feature DPDT (Double Pole Double Throw) contact configuration, providing two independent switching circuits per relay.

Q: Are there compliance differences between the two parts?

A: The 2834614 is RoHS Compliant, while the 2903329 is ROHS3 Compliant and REACH Affected. The 2903329 meets current regulatory standards for new designs.
