4.3.2 Digital Outputs, Receiver
The KRM2000 receiver has three digital outputs that can be utilized in either a source or sink
configuration. The output source current is limited by an internal 10kΩ resistor, while the input sink
current is limited to 250mA per input. If more current is required, slave relays can be added to
increase the current capabilities.
