The Weidmüller Relay Coupler leaflet provides specifications, contact types, housing options, and usage guidelines for various coupler models.
This document describes the technical data of Weidmüller relay couplers, covering contact configurations (NC, NO, change‑over), contact materials (gold‑plated, AgNi, AgSnO2, AgCdO, etc.), and switching capabilities for both low‑power (up to 40 µW) and higher‑power (up to 3.5 kVA) applications. It also details protective measures such as diode, Z‑diode, RC‑combination and varistor circuits for inductive loads.
The leaflet lists the compatible housings (EG 1, EG 2, EG 7, WAVEBOX, PLUGSERIES, etc.) and mounting options on TS 32, TS 35 × 7.5 and TS 35 × 15 rails. Compliance with standards (EN 50 178, DIN VDE 0106, IEC 255) and CE‑marking information are included, together with ordering data and part numbers for the various models.
| Pick‑up delay | < 10 ms |
|---|---|
| Drop‑out delay | < 12 ms |
| Maximum switching capacity | 3.5 kVA (resistive load) |
| Input voltage range | 5 V … 230 V AC/DC |
| Rated power consumption | 250 mW – 1 W |
The pick‑up delay is typically less than 10 ms.
Gold‑plated contacts are used for low‑power applications up to 40 µW.
The housings can be mounted on TS 32, TS 35 × 7.5 and TS 35 × 15 rails.
