Phoenix Contact 2941701 Electronic Load Relay - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2941701 is an Electronic Load Relay (ELR 3 series) designed for industrial control applications requiring solid-state switching of AC loads. This component functions as a 3-pole Form A relay with integrated heat sink packaging, rated for 9 A load current at 110–440V AC output with 24VDC input control voltage.

The 2941701 carries an obsolete product status, making identification of functionally equivalent alternatives essential for system maintenance, repair, and new design implementations. Obsolescence requires sourcing compatible substitutes that maintain identical electrical performance and mechanical compatibility within existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2941701 requires matching the following critical parameters:

• Circuit Configuration: 3PST-NO (3 Form A) topology for three independent normally-open switching channels
• Load Current Capacity: Minimum 9 A rating at specified voltage range
• Input Control Voltage: 24VDC activation voltage
• Load Voltage Range: 110–440V AC compatibility
• Output Type: AC switching capability
• Mounting Interface: DIN Rail mounting for panel integration
• Termination Method: Screw terminal connections for field wiring
• Package Form Factor: SSR with integrated heat sink for thermal management
• Compliance Status: RoHS compliance for regulatory alignment

No manufacturer-recommended substitutes have been provided for this component. Equivalent alternatives must satisfy all listed parameters to ensure functional and mechanical compatibility within existing control systems.

Engineering Selection Recommendations

Selection of substitute components for the obsolete Phoenix Contact 2941701 must prioritize functional equivalence across all specified electrical and mechanical parameters. The following criteria apply:

• Electrical Compatibility: Substitute parts must operate at identical input voltage (24VDC) and support the full load voltage range (110–440V AC) without derating
• Current Capacity: Load current rating must equal or exceed 9 A to maintain system performance margins
• Mechanical Integration: DIN Rail mounting and screw terminal termination are mandatory for retrofit compatibility
• Thermal Management: Integrated heat sink packaging is required for proper thermal dissipation in the intended application environment
• Regulatory Compliance: RoHS compliance status must be maintained for supply chain and end-use regulatory requirements
• Obsolescence Strategy: Given the obsolete status, long-term availability of substitute parts should be evaluated against active product lines from established relay manufacturers

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the Phoenix Contact 2941701?

A: A valid substitute must match all specified parameters: 3PST-NO circuit configuration, 9 A minimum load current, 24VDC input, 110–440V AC load voltage range, DIN Rail mounting, screw terminal termination, SSR with integrated heat sink package, and RoHS compliance. Deviations in any parameter compromise functional or mechanical compatibility.

Q: Can I use a relay with higher current rating as a substitute?

A: Yes, provided all other parameters remain identical. A relay rated for 10 A, 12 A, or higher current capacity is functionally compatible with the 2941701 specification, as it satisfies the minimum 9 A requirement.

Q: Are there differences in heat sink design between manufacturers?

A: Heat sink geometry and thermal performance may vary between manufacturers. Substitutes must maintain equivalent thermal dissipation characteristics to prevent component degradation under continuous load conditions. Physical dimensions must accommodate existing mounting space.

Q: What is the impact of the obsolete product status?

A: Obsolete status indicates Phoenix Contact no longer manufactures or supports the 2941701. Substitute sourcing becomes necessary for system repairs and maintenance. Availability of alternatives should be confirmed with component distributors before design finalization.

Q: Must the substitute be from Phoenix Contact?

A: No. Any manufacturer producing electronic load relays with identical electrical and mechanical specifications is acceptable. Equivalent products from established industrial relay manufacturers (Siemens, ABB, Schneider Electric, Omron, etc.) may serve as substitutes if all parameters align.

Q: How do I verify screw terminal compatibility?

A: Screw terminal pitch, wire gauge acceptance range, and torque specifications must be confirmed against installation documentation. Substitute relays must accept the same wire gauges and terminal configurations as the original 2941701 to ensure field wiring compatibility.
