The DRI relays from Weidmüller have stable plug-in contacts that prevent bending when plugging and unplugging and thus secure the installation. Thanks to the tool-free test button with end latch, tampering can be reliably detected. An LED-illuminated display facilitates clear status identification. Sockets with various screw connection systems are available for different regional requirements and applications. Two versions are available: one changeover contact, AC/DC coil and two changeover contacts, AC/DC coil. Optionally, both have a latching / momentary-action test button with colored control voltage marking (AC coil: red / DC coil: blue), a mechanical switching position indicator (for version with test button), a brightly lit status LED (AC coil: red / DC coil: green) and a freewheeling diode. The 1- and 2-changeover relays are suitable for control voltages of 12 V(DC), 24 V(DC), 48 V(DC), 110 V(DC) as well as 24 V(AC), 115 V(AC) and 230 V(AC).
