Weidmüller 944025 Terminal Block Interface Module - Equivalent & Substitute Parts

Part Overview

The Weidmüller 944025 is a 34-position interface module terminal block designed for screw connection on the process side and rectangular male connector on the control side. This component facilitates signal and power distribution in industrial control systems with rated voltage of 60VAC/75VDC and 1A per-contact current capacity. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Weidmüller 944025 requires strict alignment with the following critical parameters:

• Position Count: 34 positions must be maintained for connector compatibility
• Connection Type: Process side must support screw terminal connection; control side must be rectangular male connector with latching mechanism
• Electrical Ratings: Voltage rating of 60VAC/75VDC and 1A per-contact current capacity must be met or exceeded
• Wire Gauge Compatibility: 16-26 AWG acceptance range must be supported
• Operating Temperature Range: Minimum 0°C to 55°C operational capability required
• Series Compatibility: RS series or equivalent industrial-grade terminal block interface modules

No substitute parts have been provided in the input data. Identification of equivalent components requires sourcing from manufacturers offering 34-position interface modules with identical electrical specifications and connection configurations.

Parameter Comparison

No substitute parts are available for comparison at this time. When substitute components are identified, comparison will be conducted across the following parameters: position count, connection types, voltage rating, current rating, wire gauge range, operating temperature, and control side connector type.

Engineering Selection Recommendations

The Weidmüller 944025 is classified as obsolete. Component replacement should prioritize:

• Exact position count (34) to ensure mechanical and electrical compatibility with existing connector systems
• Identical electrical ratings (60VAC/75VDC, 1A per contact) to maintain system performance and safety margins
• Matching connection configurations on both process and control sides
• Verification of RoHS and REACH compliance status for the substitute component to ensure regulatory alignment with current manufacturing standards

Substitute selection must be validated against the original system design specifications and connector pinout documentation.

Frequently Asked Questions (FAQ)

Q: Why is the Weidmüller 944025 difficult to replace? A: The 34-position configuration combined with specific screw-terminal-to-rectangular-male connector interface is a specialized industrial configuration. Direct equivalents must match all electrical and mechanical parameters exactly.

Q: Can I use a terminal block with different position count? A: No. The 34-position count is integral to the connector interface. Substitutes with different position counts will not be mechanically or electrically compatible.

Q: What if I cannot find an exact 34-position substitute? A: Consult the original equipment manufacturer or system integrator for approved alternatives. System redesign may be required if no equivalent interface module is available.

Q: Are there compatibility concerns with wire gauge? A: The 944025 accepts 16-26 AWG wire. Substitute components must support this range. Verify wire gauge acceptance specifications before selection.

Q: Does operating temperature range affect substitution? A: Yes. The 0°C to 55°C range is a functional requirement. Substitute components must support at minimum this temperature range for equivalent operation.

Q: What role does the latching mechanism play? A: The rectangular male connector with latches ensures secure mating and prevents accidental disconnection. Substitute components must include equivalent latching features.
