PECIFICATION
XM-2DR can be used as I/O extension module and it offers two NO/NC input lines as well as two
relay outputs with isolated NO/NC contacts. The module is addressable and it can communicate
only with devices, which can use RACS Clock&Data standard, namely RACS 4 controllers.
Optionally, XM-2DR can also operate as standalone device and then its relay outputs can be
activated by means of high/low voltage at corresponding input lines. In standalone mode, the XM-
2DR does not communicate by means of RACS Clock&Data.
Two versions are available i.e. XM-2DR is equipped with plastic enclosure and is dedicated to
installation on DIN 35mm rail, while XM-2DR-BRD is electronic module without any enclosure but it
is accompanied with adapter for installation on DIN 35mm rail.
