Phoenix Contact 2981114 Safety Relay - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2981114 is a 3PST safety relay rated for 6A at 24VAC/DC, designed for DIN Rail mounting with screw terminal connections. This component is classified as Obsolete, making identification of suitable substitute parts essential for system maintenance and new designs. The relay features silver tin oxide and gold contact materials with a 50 ms operate and release time specification. Due to its obsolete status, equivalent active alternatives must be evaluated based on electrical and mechanical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2700524 qualifies as a direct substitute for the 2981114 based on the following critical parameters:

Matching Parameters:

• Coil Voltage: 24VAC/DC (identical)
• Contact Form: 3PST-NO (3 Form A) (identical)
• Contact Rating (Current): 6 A (identical)
• Switching Voltage: 250VAC, 250VDC - Max (identical)
• Mounting Type: DIN Rail (identical)
• Termination Style: Screw Terminal (identical)

Differences Requiring Evaluation:

• Product Status: 2700524 is Active (vs. Obsolete 2981114)
• Operate Time: 150 ms (vs. 50 ms for 2981114)
• Release Time: 20 ms (vs. 50 ms for 2981114)
• Operating Temperature Range: -40°C ~ 55°C (vs. -20°C ~ 55°C for 2981114)
• Coil Current: 103 mA (vs. 120 mA for 2981114)
• Contact Material: Silver Tin Oxide (AgSnO) only (vs. AgSnO + Au for 2981114)
• RoHS Status: ROHS3 Compliant (vs. RoHS Compliant for 2981114)

The 2700524 maintains electrical and mechanical compatibility while offering extended temperature range and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2700524 is suitable as a substitute for the obsolete 2981114 in applications where the following conditions are met:

Compliance Considerations:

• Both parts maintain EAR99 export classification
• The 2700524 carries ROHS3 compliance, meeting current regulatory requirements
• The 2700524 is REACH Affected, requiring compliance verification for specific applications

Operational Suitability:

• The 2700524 operates across an extended temperature range (-40°C to 55°C), providing broader environmental compatibility
• Reduced coil current (103 mA vs. 120 mA) results in lower power consumption
• Increased operate time (150 ms vs. 50 ms) must be evaluated against application timing requirements
• Faster release time (20 ms vs. 50 ms) improves response characteristics in safety-critical circuits

Availability:

• The 2700524 is an active product with current inventory availability, eliminating supply chain risk associated with the obsolete 2981114

Frequently Asked Questions (FAQ)

Q: Can the 2700524 directly replace the 2981114 in existing installations?

A: The 2700524 maintains identical coil voltage, contact form, current rating, and switching voltage specifications. However, the increased operate time (150 ms vs. 50 ms) must be evaluated against circuit timing requirements. Mechanical compatibility is confirmed through identical DIN Rail mounting and screw terminal termination.

Q: What is the significance of the operate time difference?

A: The 2981114 operates in 50 ms while the 2700524 requires 150 ms. This difference affects response speed in time-sensitive applications. System designers must confirm that the 150 ms operate time is acceptable for the intended safety or control function.

Q: Are there compliance differences between these parts?

A: The 2700524 carries ROHS3 and REACH compliance certifications, while the 2981114 carries RoHS compliance. Both maintain EAR99 export classification. Applications subject to REACH regulations must use the 2700524.

Q: Does the contact material difference affect performance?

A: The 2981114 features both silver tin oxide and gold contact materials, while the 2700524 uses silver tin oxide only. Both materials are suitable for the specified 6A switching application at 250VAC/250VDC maximum.

Q: What is the temperature range impact?

A: The 2700524 operates from -40°C to 55°C, compared to -20°C to 55°C for the 2981114. The extended lower temperature range provides additional operational flexibility for cold environment applications.

Q: How does the reduced coil current affect circuit design?

A: The 2700524 draws 103 mA compared to 120 mA for the 2981114. This 17 mA reduction decreases power consumption and heat generation, potentially reducing coil driver requirements in the control circuit.
