RCD21 Open collector module
The RCD21 open collector module allows existing controllers and devices to be upgraded or combined with a wireless interface.
32 transmission codes can be paired with each open collector output. Open collector outputs activate the selected mode accordingly. A transmission code can be paired with any number of outputs.
The programming is retained even in the event of a power failure. Only four OC outputs are used for activating the “Battery Low” RCD21 variant.
A Battery Low output (BL) is allocated to each switching output. This BL output signals low voltage telegrams by switching the corresponding output for one second.
