Weidmüller 1100410000 General Purpose Relay SPDT 6A 48V - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1100410000 is a general purpose relay with SPDT (Single Pole Double Throw) contact configuration, rated for 6A at 48VDC coil voltage. This DIN rail-mounted relay is designed for industrial control applications requiring reliable switching of AC and DC loads up to 250VAC. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and new installations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1100410000 is determined by the following critical parameters:

• Contact Form: SPDT (1 Form C) configuration must be maintained for circuit compatibility
• Contact Rating: 6A minimum current capacity required
• Mounting Type: DIN Rail mounting must be preserved for mechanical fit
• Termination Style: Screw Terminal connection required
• Switching Voltage: 250VAC maximum switching capability must be met or exceeded
• Coil Voltage Compatibility: 48V supply voltage (DC or AC/DC dual rated acceptable)
• Compliance: RoHS Compliant and REACH Unaffected status required

The substitute part Weidmüller 1122790000 meets all these criteria with equivalent electrical and mechanical specifications, with the distinction that it accepts both 48VAC and 48VDC coil voltage, providing broader application flexibility.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1122790000 is the direct substitute for the obsolete 1100410000. Both relays maintain identical contact form, current rating, switching voltage, and termination specifications required for mechanical and electrical compatibility.

The 1122790000 offers the following advantages:

• Active Product Status: Currently manufactured and supported by Weidmüller, ensuring long-term availability and supply chain reliability
• Dual Voltage Coil: Accepts both 48VAC and 48VDC, providing operational flexibility in systems with either AC or DC control supplies
• Extended Temperature Range: Operating range of -40°C to 60°C exceeds the original -25°C to 40°C specification, suitable for wider environmental conditions
• Compliance Maintained: Retains RoHS Compliant and REACH Unaffected certifications

Both relays are RoHS Compliant and REACH Unaffected, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1122790000 directly replace the 1100410000 in existing installations?

A: Yes. Both relays share identical SPDT contact form, 6A current rating, 250VAC switching voltage, DIN Rail mounting, and screw terminal connections. The 1122790000 is electrically and mechanically compatible as a direct substitute.

Q: What is the difference in coil voltage specification?

A: The original 1100410000 operates on 48VDC only. The substitute 1122790000 is rated for 48VAC/DC, meaning it functions with either 48 volts AC or DC supply. This dual-voltage capability does not affect compatibility in 48VDC applications.

Q: Are there differences in switching performance?

A: The 1122790000 has a faster operate time (9 ms vs. 12 ms) and slower release time (23 ms vs. 11 ms). These timing differences are within acceptable ranges for general purpose relay applications and do not affect standard switching functionality.

Q: Does the operating temperature range difference matter?

A: The 1122790000 supports -40°C to 60°C versus the original -25°C to 40°C. The substitute provides a wider operating envelope, making it suitable for applications in more extreme thermal environments without performance degradation.

Q: Are both relays compliant with environmental regulations?

A: Yes. Both the 1100410000 and 1122790000 are RoHS Compliant and REACH Unaffected, meeting current environmental and safety standards for industrial components.

Q: What is the packaging difference?

A: The original 1100410000 was supplied with socket inclusion. The 1122790000 is supplied in bulk packaging. Verify socket requirements for your application if the relay socket is a separate procurement item.
