Phoenix Contact 2834559 General Purpose Relay DPDT 230VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834559 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 8A at 230VAC switching voltage. This DIN rail-mounted relay features a 230VAC coil, non-latching operation, and includes a lighted indicator with varistor protection. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and replacement applications.

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834559 is constrained by the following critical parameters that must align between the main part and any substitute:

Mandatory Matching Parameters:

Mounting Type: DIN Rail
Contact Form: DPDT (2 Form C)
Coil Voltage: 230VAC
Coil Type: Non Latching
Termination Style: Screw Terminal

Allowable Variation Parameters:

Contact Rating (Current): The 2834559 is rated for 8A. Substitutes with lower current ratings (such as 50mA) represent a functional downgrade and are suitable only for applications where the actual load current does not exceed the substitute's rating.
Switching Voltage: The 2834559 supports 250VAC/250VDC maximum. Substitutes with lower switching voltage ratings must not be used in applications exceeding their specified limits.
Operating Temperature Range: The 2834559 operates from -25°C to 60°C. Substitutes with different ranges must be evaluated against actual environmental conditions.
Product Status: Active substitutes are preferred over obsolete parts for new designs and long-term availability.

Engineering Selection Recommendations

Phoenix Contact 2903343 (RIF Series):

The 2903343 shares the core functional architecture with the 2834559: identical DIN rail mounting, DPDT contact configuration, 230VAC coil voltage, and non-latching operation with screw terminal termination. Both relays maintain equivalent coil current specifications (5.5mA vs. 6mA) and identical operate time (12ms).

The 2903343 is an active product with ROHS3 compliance and REACH affected status, providing superior long-term availability compared to the obsolete 2834559. The relay includes socket mounting capability as an additional feature.

Critical Limitation: The 2903343 contact rating is 50mA at 30VAC/36VDC maximum switching voltage, representing a significant reduction from the 2834559's 8A at 250VAC/250VDC rating. This substitute is suitable only for low-current signal switching applications. Applications requiring the original 8A capacity or 250V switching capability cannot use this substitute.

Temperature Consideration: The 2903343 operating range (-40°C to 50°C) differs from the 2834559 (-25°C to 60°C). The lower upper temperature limit (50°C vs. 60°C) must be evaluated against actual installation environments.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903343 directly replace the 2834559 in all applications?

A: No. The 2903343 is suitable only for applications where the load current does not exceed 50mA and the switching voltage does not exceed 30VAC or 36VDC. The 2834559's 8A capacity and 250V switching capability cannot be matched by the 2903343. Verify actual circuit requirements before substitution.

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

A: Both relays share identical coil voltage (230VAC), contact configuration (DPDT), and mounting type (DIN rail). The primary difference is contact rating: the 2834559 handles 8A at 250VAC/250VDC, while the 2903343 handles 50mA at 30VAC/36VDC. The 2903343 is designed for low-current signal switching, not power switching.

Q: Why is the 2834559 listed as obsolete?

A: The 2834559 is an obsolete product from the PR1-R series. The 2903343 from the active RIF series represents Phoenix Contact's current offering for general purpose DPDT relays with 230VAC coils on DIN rail mounting.

Q: Are there any packaging differences?

A: The 2834559 packaging is listed as standard, while the 2903343 is supplied in bulk packaging. Both use screw terminal termination and include socket mounting options in the 2903343.

Q: What compliance certifications apply to each relay?

A: The 2834559 is RoHS Compliant. The 2903343 is ROHS3 Compliant and REACH Affected. Both carry EAR99 ECCN classification.
