Description

With the REL-MR-...21 plug-in miniature relay, the high end of the latest relay developments are made available to the innovative PLC range. Despite its compact dimensions, the device is rugged and equipped with features which are not normally found in plug-in relays: –5 m m w i d e – High level of operational safety – Cadmium-free, environmentally friendly power contacts up to 250 V AC/6 A – Available with gold plating for low power switching levels (mA) as an option –4 k V rms electrical isolation between input and output – Safe isolation according to EN 50178 – High degree of protection, up to IP67 depending on the type The miniature relays are not just designed to be used as components for the PLC range, but can also be used as PCB relays in industrial products of any kind, such as: – Interface technology, timer relays – Measuring and control technology – PLC and bus I/O modules Make sure you always use the latest documentation.
