Grayhill 70M-IAC24 AC Input Module - Equivalent & Substitute Parts

Part Overview

The Grayhill 70M-IAC24 is an AC input module designed to convert 120VAC supply voltage to 24VDC output for control and signal applications. This module operates at 8mA input current and delivers 10mA output current with 20ms response times for both turn-on and turn-off operations. The part is classified as Active product status and is available in Mini style packaging with Yellow color designation. Substitute parts are identified when electrical specifications, mechanical compatibility, and compliance certifications remain equivalent across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 70M-IAC24 is determined by equivalence across the following critical parameters:

• Input voltage specification: 120VAC
• Output voltage specification: 24VDC
• Input current rating: 8mA
• Output current rating: 10mA
• Response time characteristics: 20ms turn-on and turn-off
• Product status: Active
• Compliance certifications: RoHS non-compliant, REACH Unaffected, ECCN EAR99

The 70-IAC24 substitute part maintains identical electrical performance specifications and compliance status. Mechanical differences in style designation (Mini versus Standard) and the presence of a hold-down screw feature do not affect electrical substitutability when circuit requirements are limited to the specified voltage and current parameters.

Parameter Comparison

Engineering Selection Recommendations

The 70-IAC24 serves as a direct electrical substitute for the 70M-IAC24 based on identical voltage, current, and timing specifications. Both parts maintain Active product status and share equivalent compliance certifications including RoHS non-compliance and REACH Unaffected designation.

Selection between these parts should be based on mechanical form factor requirements. The 70M-IAC24 Mini style is suitable for space-constrained applications, while the 70-IAC24 Standard style with hold-down screw feature provides mechanical retention capability for panel-mount or vibration-prone installations.

Both parts carry identical ECCN EAR99 and HTSUS 8536.49.0055 classifications, ensuring equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 70-IAC24 replace the 70M-IAC24 in existing designs?

A: Yes. The 70-IAC24 provides identical electrical performance with 120VAC input, 24VDC output, 8mA input current, and 10mA output current. The primary difference is mechanical form factor: Mini versus Standard style. Substitution is valid when circuit board layout accommodates the Standard style dimensions and when the hold-down screw feature does not create interference.

Q: What is the significance of the hold-down screw feature on the 70-IAC24?

A: The hold-down screw on the 70-IAC24 Standard style provides mechanical retention for panel-mount applications or environments subject to vibration. The 70M-IAC24 Mini style does not include this feature. Selection depends on mechanical mounting requirements, not electrical performance.

Q: Are there compliance differences between these parts?

A: No. Both parts share identical RoHS non-compliance status, REACH Unaffected designation, Moisture Sensitivity Level 1 (Unlimited), ECCN EAR99, and HTSUS 8536.49.0055 classification.

Q: What determines whether these parts are interchangeable?

A: Interchangeability is determined by the following electrical parameters: 120VAC input voltage, 24VDC output voltage, 8mA input current, 10mA output current, and 20ms response times. Mechanical differences in style and features do not affect electrical substitutability when these specifications are met.

Q: Which part should be selected for new designs?

A: Selection should be based on available inventory, mechanical space constraints, and mounting method requirements. Both parts are Active status. The 70M-IAC24 Mini style is preferred for compact applications; the 70-IAC24 Standard style is preferred when mechanical retention via hold-down screw is required.
