Phoenix Contact 2834601 General Purpose Relay DPDT 24VDC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834601 is a general purpose relay with DPDT (2 Form C) contact configuration, designed for 24VDC coil operation with 8A contact rating. This relay is mounted on DIN rail and features a non-latching coil with integrated diode and lighted indicator. The product is currently obsolete, making identification of suitable substitute components necessary for system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834601 is determined by the following critical parameters:

• Coil Voltage: 24VDC operation is mandatory for direct replacement in existing circuits
• Contact Form: DPDT (2 Form C) configuration must be maintained for equivalent switching capability
• Mounting Type: DIN Rail mounting ensures mechanical compatibility with existing installations
• Coil Type: Non-latching operation is required for functional equivalence
• Termination Style: Spring terminal connection must be preserved for installation compatibility
• Features: Integrated diode and lighted indicator are standard features for this product category

The substitute part Phoenix Contact 2903330 shares the core functional parameters (24VDC coil, DPDT contact form, DIN rail mounting, non-latching coil, spring terminals, diode and lighted indicator) but operates at a reduced contact current rating of 50 mA versus the original 8 A specification. This substitution is valid only for applications where the lower contact current rating is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903330 is an active product with current manufacturing status, whereas the 2834601 is obsolete. Both components comply with RoHS requirements and share identical coil voltage, contact form, mounting configuration, and switching timing characteristics.

Selection between these parts depends on application current requirements. The 2834601 supports 8 A contact current with 250VAC/250VDC maximum switching voltage. The 2903330 operates at 50 mA contact current with 30VAC/36VDC maximum switching voltage. The 2903330 provides an extended operating temperature range of -40°C to 70°C compared to the original -25°C to 60°C specification.

For applications requiring the full 8 A contact current capability of the original part, the 2903330 is not suitable. For low-current switching applications within the 50 mA specification, the 2903330 provides an active alternative with improved temperature performance and current RoHS3 compliance status.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903330 directly replace the 2834601 in all applications?

A: Direct replacement is limited by contact current rating. The 2903330 is rated for 50 mA maximum contact current, while the 2834601 supports 8 A. Substitution is valid only for applications operating within the 50 mA specification.

Q: Are the coil voltages identical between these relays?

A: Both relays operate on 24VDC coil voltage with nearly identical coil current specifications (19 mA for 2834601, 18 mA for 2903330), ensuring compatible control circuit integration.

Q: What is the difference in switching voltage capability?

A: The 2834601 switches up to 250VAC or 250VDC maximum. The 2903330 switches up to 30VAC or 36VDC maximum. Applications requiring higher switching voltages must use the original 2834601 specification or identify alternative parts with higher voltage ratings.

Q: Do both relays have the same physical mounting?

A: Both relays use DIN rail mounting with spring terminal connections, ensuring mechanical compatibility in existing installations.

Q: What is the temperature operating range difference?

A: The 2834601 operates from -25°C to 60°C. The 2903330 provides an extended range of -40°C to 70°C, offering improved performance in wider temperature environments.

Q: Are both relays RoHS compliant?

A: The 2834601 is RoHS Compliant. The 2903330 is ROHS3 Compliant, representing current regulatory compliance status.
