RUW Timer & Protection Modules

Schneider Electric RUW Timer and Protection Modules add timing and coil-protection functions to compatible Harmony electromechanical relay (EMR) sockets. The RUW lineup features three products. The RUW101MW provides multifunction time-delay control for hard-wired logic systems, while the RUW240BD and RUW241P7 provide diode and RC circuit protection, respectively. These compact modules offer flexible installation, equipment updates, and post-installation modifications without requiring replacement of the relay system. The RUW101MW multifunction timer module accepts a 24V to 240V AC/DC control circuit and works with RPZ sockets with three or four changeover (C/O) contacts and RUZ sockets with two or three C/O contacts. The module's selectable timing functions simplify adding time-delay control to hard-wired circuits, including systems that do not use a programmable logic controller (PLC).
