The NXG-504 adds 4 additional relay outputs to the xGen range of panels. Via a jumper, each Single Pole Double Throw (SPDT) Form C relay output can be configured in 3 different modes: as dry contact, or to switch the bus or externally supplied voltage to the output terminal, or to switch the bus ground to the output terminal. This allows to use the module in different applications. The status LED next to each output shows the actual state of the relay. The module is DIN-rail mountable and can be added into the control panel enclosure or can be installed remotely. The xGen bus input as well as each relay output is wired on a removable terminal block allowing easy wiring and maintenance. Enrolling the module and programming the outputs is done from the control panel. The firmware of the module is upgradeable remotely via DLX900 or locally using the USB flash device.
