Phoenix Contact 2981460 Safety Relay - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2981460 is a safety relay module featuring 6PST contact configuration (4 Form A, 2 Form B) with 6A contact rating and 120VAC/DC coil voltage. This DIN rail-mounted relay is designed for safety-critical applications requiring certified switching control. The part is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance and replacement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2981460 is determined by the following critical parameters that must remain constant across equivalent parts:

• Contact configuration: 6PST with 4 Form A and 2 Form B contacts
• Contact current rating: 6 A minimum
• Maximum switching voltage: 250VAC/250VDC
• Mounting interface: DIN rail
• Termination method: Screw terminal
• Contact material composition: Silver Tin Oxide (AgSnO)
• Operating temperature range: -20°C to 55°C minimum

The primary variable parameter in substitute selection is coil voltage. The 2981460 operates at 120VAC/DC; however, functionally equivalent alternatives may operate at different coil voltages provided all other electrical and mechanical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2981444 is a direct functional equivalent to the 2981460 within the PSR safety relay series. Both parts maintain identical contact configuration, current rating, switching voltage capability, and mechanical mounting specifications. The 2981444 is currently in active production status, whereas the 2981460 is obsolete.

The primary distinction between these parts is coil voltage: the 2981460 operates at 120VAC/DC while the 2981444 operates at 24VAC/DC. Selection between these parts depends on the control circuit voltage available in the target application. Both parts meet RoHS compliance requirements and are suitable for safety-critical applications requiring certified relay performance.

Frequently Asked Questions (FAQ)

Q: Can the 2981444 directly replace the 2981460 in all applications?

A: The 2981444 is mechanically and electrically compatible with the 2981460 in terms of contact configuration, current rating, and switching voltage. However, the coil voltage differs (24VAC/DC versus 120VAC/DC). Substitution is valid only if the control circuit can supply the required 24VAC/DC coil voltage. If the control circuit is designed for 120VAC/DC operation, a different coil voltage substitute is not appropriate.

Q: What are the key parameters that must match for substitution?

A: Critical matching parameters include contact form (6PST-4NO/2NC), contact current rating (6 A), maximum switching voltage (250VAC/250VDC), DIN rail mounting, screw terminal termination, and operating temperature range (-20°C to 55°C). Coil voltage is application-dependent and may vary between equivalent parts.

Q: Is the 2981444 suitable for safety-critical applications?

A: Yes. The 2981444 is part of the Phoenix Contact PSR safety relay series and maintains the same contact material (Silver Tin Oxide) and electrical specifications as the 2981460. Both parts are RoHS compliant and suitable for certified safety applications.

Q: What is the difference in coil current between these parts?

A: The 2981460 draws 12 mA at 120VAC/DC coil voltage, while the 2981444 draws 52 mA at 24VAC/DC coil voltage. This difference reflects the lower coil voltage of the 2981444 and does not affect contact switching performance.

Q: Are there packaging differences between the main part and substitute?

A: The 2981460 is listed with standard packaging, while the 2981444 is supplied in bulk packaging. Both are DIN rail-mounted modules with identical mechanical interfaces.
