This document introduces a full-featured industrial plug-in relay that serves as a single pole interface to four pole power switching, enabling low level signal to high power DC switching. It offers options for latching and low consumption coil, as well as plug-in timer cube.
This guide presents the full range of Releco's MRC, QRC and IRC plug‑in relays, covering general information, part numbers, and application types. It includes tables of contacts, coil options, and socket modules for each series.
Technical details such as contact materials, coil constructions, protection circuits, and environmental ratings are described, along with specifications for switching current, voltage, inrush current, and operating times. Custom relay options and protection against transients are also covered.
| Max. switching current | 10 A |
|---|---|
| Peak inrush current (20 ms) | 30 A |
| Nominal coil power | 2.2 VA (AC), 1.3 W (DC) |
| Operate time | 16 ms |
| Release time | 8 ms |
| Isolation rating | EN60947 pollution 3, GrC —250 V |
Silver‑nickel (AgNi) and silver‑tin oxide (AgSnOz) are used as standard contact materials for all models.
Releco relays can include integrated protection circuits or modules such as RC suppressors, diodes, or bridge rectifiers that are plugged into dedicated sockets.
