XM-2DR is an I/O expander dedicated to systems using RACS CLK/DTA protocol.
Expander offers two NO/NC inputs and two relay outputs with 1.5 A/30 VDC and 5 A/30 VDC max load respectively.
Optionally, XM-2DR can be used as a standalone device (without communication with master device), when so, its outputs are controlled by signals applied to its inputs.
