Weidmuller WMF 2.5 terminal series designed for process and power generation industries.

Weidmuller introduced the WMF 2.5 (Weidmuller Multi Function), a terminal block series designed for DCS marshalling applications. The 5mm-wide block features  feed-through, fusing and quick disconnects, incorporate an integrated shield or ground (PE) connection, and have three separate jumpering channels to accommodate parallel and series jumpering. In addition to the ability to terminate each individual signal with a screw connection, the WMF 2.5 series offers the option to use a pre-assembled cable that features Weidmuller’s pluggable BLZ connectors. The connectors can be plugged directly into the bank of terminal blocks, creating a “plug-and-play” option.

Weidmuller’s new WMF 2.5 terminal block series includes clearly identified, black fuse terminals and an optional LED status indicator  shows if the fuse is OK or needs replacement. The LED circuit is designed to produce minimal leakage current (<0.5 mA) when the fuse is blown, eliminating the potential for false status indication to the PLC or DCS. The WMF 2.5 terminals also feature the company’s standard setting, vibration-proof and maintenance-free screw clamp termination technology. They are electrically rated for 600V/25A/26-12AWG, and have UL and CSA approvals.
