Product Description

The Single relay REL-IR4/230AC/4X21/EX is a pluggable industrial relay designed for reliability in demanding environments. It operates at an input voltage of 230 V AC and is compatible with RIF-2.../EX bases, making it suitable for applications in hazardous areas classified under ATEX/IECEx (zone 2) and Ex zone class I, div. 2.

This relay features four changeover contacts and includes a mechanical switch position indicator, providing clear status visibility. The device is characterized by non-polarized operation and a typical input current of 6.5 mA, with a response time ranging between 5 ms and 15 ms depending on the phase relation.

Constructed to withstand harsh conditions, it has a degree of protection rated at RT III, ensuring durability across a wide ambient temperature range from -40 °C to 55 °C. The relay's electrical service life is approximately 20 million cycles, making it suitable for applications requiring long-term reliability.

Notably, the device supports maximum switching voltages of 250 V AC/DC and a limiting continuous current of 6 A, with a maximum inrush current of 16 A for 20 ms at the normally open contacts. Connections are facilitated through a plug-in method for ease of installation.
