Weidmüller 944026 Terminal Block Interface Module - Equivalent & Substitute Parts

Part Overview

The Weidmüller 944026 is a 40-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 support for 16-26 AWG wire gauges and rated for 60VAC/75VDC operation. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new installations where legacy component sourcing becomes impractical.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Weidmüller 944026 requires functional equivalence across the following critical parameters:

• Position Count: 40 positions minimum to maintain signal routing capacity
• Connection Type: Screw terminal on process side; rectangular male connector on control side
• Electrical Ratings: Minimum 60VAC/75VDC voltage rating and 1 A per-contact current capacity
• Wire Gauge Compatibility: Support for 16-26 AWG conductor sizes
• Operating Temperature Range: Minimum 0°C to 55°C operational envelope
• Connector Interface: Latching mechanism on control side for secure mating

No substitute parts have been provided in the input data. Equivalent alternatives must meet all parameters listed above to ensure direct functional replacement without system redesign.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 944026 carries obsolete product status. When selecting replacement components, prioritize parts that maintain identical electrical specifications (60VAC/75VDC, 1 A per contact) and mechanical interface compatibility (40-position screw terminal to rectangular male connector configuration). REACH compliance status should be verified for new alternatives to ensure regulatory alignment with current procurement standards. Connector keying and latching mechanism compatibility must be confirmed to prevent installation errors in existing harness assemblies.

Frequently Asked Questions (FAQ)

Q: What makes a terminal block a valid substitute for the Weidmüller 944026? A: A substitute must provide 40 positions, screw-type process-side connection, rectangular male control-side connector, support for 16-26 AWG wire, and electrical ratings of at least 60VAC/75VDC with 1 A per-contact capacity.

Q: Can I use a terminal block with fewer than 40 positions? A: No. The 40-position configuration is a core functional requirement. Reduced position counts will not accommodate the full signal routing of the original design.

Q: Are there mechanical compatibility concerns when substituting this interface module? A: Yes. The rectangular male connector interface and latching mechanism must match the original specification to ensure proper mating with existing control-side receptacles and harness assemblies.

Q: What is the significance of the 16-26 AWG wire gauge specification? A: This range defines the acceptable conductor sizes for screw terminal insertion. Substitutes must support this identical range to maintain compatibility with existing field wiring.

Q: Why is the operating temperature range important for substitution? A: The 0°C to 55°C range establishes the thermal envelope for safe operation. Substitutes must meet or exceed this range to function reliably in the intended application environment.
