GPI Signal Control Panel with 2 Buttons - KR-21C for Device Management

The remote control is designed to control external devices using GPI signals, 2 buttons, 2 GPI connectors. Pressing a button generates the following GPI signals: open collector, fully isolated relay switching pair, relay switching pair with grounded normally open contact. When the power supply is switched off, the relay pairs are open, and when the power is switched on again, the state of the panel is restored.

LED backlighting of the button indicates the internal state of the output signal or the presence of the input signal. The backlighting colour is selected by means of a slider switch. Buttons of the remote control can be combined into groups of dependence; belonging of a button to one of the groups implies that pressing the button switches it on, switching off all other buttons of the given group.

The remote control is powered from 230 V AC mains, or from a 9-12 V DC source. The remote control has side corners for mounting in a telecoms rack. The warranty period is 24 months.
