The DigiFlex DXA-16C-2 16-Channel Bidirectional Contact Closure System Transceiver Card from Meridian Technologies transmits and receives 16 channels of bidirectional contact closure signal over a single multimode fiber channel. For proper operation, it is necessary to pair this card with the DigiFlex DXB-16C-2 Side B Transceiver Card.
The transceiver's card type design allows for easy configuration of the system. It can be installed in Meridian's card / desk chassis and 19" racking frames. The system can be configured in either star (module-to-rack) or trunking (rack-to-rack) configurations. It can be converted to a standalone module with the separately available SR-1000 2-Slot Desk / Wall Mount Chassis (87 to 264 VAC).
