The relay couplers and multifunction timing relays from CONTA-CLIP’s new Interface Relay Compact (IRC) program embody a new coupling relay strategy: merely 6.2 mm wide, the units require minimal space while enabling simple installation and ease of use. Thanks to interchangeable relays or optocouplers, they can be adapted to various requirements.
Differently colored cross-connection combs additionally facilitate installation and ensure a clear layout. The program consist of five different types: the basic version is the IRC relay coupler for universal use. Like all other units from this series, it features either an innovative pressure spring wire connection system (PushIn) or an established screw wire-connect system.
Similar to the basic version, the IRCP model with an optional integrated fuse module can be used in all systems. It provides the possibility to protect each coupling relay output with a replaceable 5 x 20 mm standard micro-fuse in order to limit the effects of overcurrents to the area before the fuse. The fuses come in a plug-in SM-IRC module, thus enabling quick and easy exchanges.
The input/output models IRCPI and IRCPO provide an additional wire port that can be cross-connected, allowing for all three wires of a sensor in a PLC input or all wires of an output-side power relay or contactor to be connected directly to the coupling relay. Thereby, no further terminals are required, making the installation especially space-saving and concise.
The MFR-IRCP model, a time-function coupler component that acts as a time relay, completes CONTA-CLIP’s IRC series. The relay coupler features DIP switches that allow users to set eight time functions and four time ranges between 0.1 s and 6 h. It also features the innovative receptacle for holding additional 5 x 20 mm SM-IRC fuse modules.
