AVMR0037 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The AVMR0037 is a general purpose relay manufactured by Red Lion Controls, designed for DIN rail mounting with SPST-NO (Single Pole Single Throw - Normally Open) contact configuration. The relay operates on 24VAC/DC coil voltage with a 3A contact rating and supports switching voltages up to 250VAC and 30VDC. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain system functionality and ensure continued availability for new installations and replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AVMR0037 is based on strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Mounting type: DIN Rail
• Coil voltage: 24VAC/DC
• Contact form: SPST-NO configuration
• Coil type: Non Latching
• Termination style: Screw Terminal

Secondary Compatibility Criteria:

• Contact rating current: Equal to or greater than 3A
• Switching voltage: Equal to or greater than 250VAC and 30VDC
• Operating temperature range: Encompasses or exceeds -20°C ~ 50°C
• Coil current: Lower values indicate improved efficiency

The Phoenix Contact 2982236 satisfies all primary criteria and exceeds secondary criteria with a 6A contact rating, extended temperature range (-20°C ~ 60°C), and higher switching voltage capability (250VAC, 250VDC). The substitute part is active and RoHS3 compliant, providing regulatory compliance advantages over the obsolete AVMR0037.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2982236 is the designated equivalent for the obsolete AVMR0037. Selection of this substitute is justified on the following engineering and compliance grounds:

Functional Equivalence: The 2982236 maintains all critical operational parameters required for direct substitution, including identical coil voltage (24VAC/DC), contact form (SPST-NO), and termination method (Screw Terminal). The higher contact rating (6A versus 3A) and extended switching voltage capability (250VDC versus 30VDC) provide enhanced performance margins without introducing incompatibility.

Product Status and Availability: The AVMR0037 is obsolete and no longer in active production. The 2982236 is an active product with confirmed inventory availability (1087 Pcs), ensuring reliable sourcing for current and future applications.

Regulatory Compliance: The 2982236 carries RoHS3 compliance certification and REACH affected status, meeting current environmental and regulatory requirements. The AVMR0037 compliance status is not specified, presenting potential regulatory risk in new system designs.

Operational Characteristics: The substitute exhibits marginally longer operate time (6ms versus 5ms) and higher coil current draw (11mA versus 6.5mA), which are acceptable trade-offs for improved contact capacity and temperature range. The extended operating temperature range (-20°C ~ 60°C) provides additional thermal margin.

Socket and Features: Both relays include socket mounting capability and screw terminal connections. The 2982236 includes a lighted indicator feature not present in the AVMR0037, providing additional operational visibility without affecting substitution compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2982236 directly replace the AVMR0037 in existing installations?

A: Yes. The 2982236 is a direct functional equivalent with identical coil voltage, contact form, mounting type, and termination style. The higher contact rating and switching voltage capability ensure compatibility with all applications designed for the AVMR0037. Physical DIN rail mounting dimensions must be verified for panel space constraints.

Q: What is the significance of the higher 6A contact rating on the 2982236 compared to the 3A rating of the AVMR0037?

A: The 6A rating indicates the substitute can safely switch higher currents without contact degradation. Applications using the AVMR0037 at or below 3A will operate within the 2982236 specification with additional safety margin. No circuit redesign is required.

Q: Does the 1mA increase in coil current (from 6.5mA to 11mA) affect system design?

A: The coil current increase is within acceptable limits for standard 24VAC/DC control circuits. Power supply capacity should be verified if multiple relays are added to a system, but existing installations with adequate supply capacity will not require modification.

Q: Why is the operate time 1ms longer on the 2982236?

A: The 6ms operate time of the 2982236 versus 5ms for the AVMR0037 represents a minor timing difference. For general purpose relay applications, this 1ms variance is not significant. Applications with critical timing requirements below 1ms should be evaluated individually.

Q: What is the advantage of the extended operating temperature range on the 2982236?

A: The 2982236 operates from -20°C to 60°C, compared to -20°C to 50°C for the AVMR0037. This 10°C extension at the upper limit provides additional thermal margin for installations in warm environments or enclosures with elevated ambient temperatures.

Q: Is the lighted indicator feature on the 2982236 compatible with the AVMR0037 circuit design?

A: The lighted indicator is an additional feature that does not affect core relay function. Existing circuits designed for the AVMR0037 will operate the 2982236 without modification. The indicator provides optional operational status visibility.

Q: Are there any packaging or inventory considerations for the 2982236?

A: The 2982236 is supplied in bulk packaging with 1087 Pcs currently in stock. The AVMR0037 is obsolete with 1086 Pcs remaining inventory. For new designs and long-term applications, the 2982236 is the recommended selection due to active production status.

Q: Does the RoHS3 compliance of the 2982236 affect compatibility?

A: RoHS3 compliance indicates the substitute meets current environmental standards for hazardous substance restrictions. This compliance status is advantageous for new system designs and regulatory requirements. The AVMR0037 compliance status is not specified, making the 2982236 the preferred choice for applications subject to environmental regulations.
