KR-21C-K - Active control panel, GPI signals, 2 identical channels, 1 enable key, PC control.

The remote control is designed to control external devices using GPI signals. Additionally, the remote control is equipped with an enable key output. Turning the key to the "ON" position closes two pairs of contacts on the corresponding output. Formation of GPI signals by pressing the buttons on the front panel is completely independent of the operation of the enable keys. When the power supply is switched off, the relay pairs are open, when the power supply is switched on, the status of the panel is restored. One of the GPI signals can be programmed: level, 200ms pulse and 400ms pulse. The buttons of the control panel can be combined into "dependency groups", i.e. pressing a button switches it on while switching off another button. If the pulse type GPI output signal generation mode is selected for the buttons, the signal is output only to the output corresponding to the pressed button. LED backlighting of the buttons indicates the internal state of the output signals or the presence of the input signal. The warranty period is 24 months.
