ICPDAS DB-24SSRDC
24-channel Solid State Relay Output Board
● 24 optically isolated digital output channels
● 24 form A solid-state relays
● Switch up to 4 A at 250 VAC/50 VDC
● One OPTO-22 Compatible Connector and one 37-pin D-sub connector and one 20-pin connector
● Connects directly to OPTO-22 compatible board or any 722, 724 series board
● LED’s indicated relay status
● Screw terminals for easy field wiring
The DB-24SSRDC includes 24 normally open, or form A, solid-state relays The board interface to filed logic signals, eliminating ground-loop problems and isolating the host computer from damaging voltages.
The user can use the DB-24SSRDC to switch high voltage load, up to 240 VAC/50 VDC and up to 4 A. The relay is energized by applying a 5-voltage signal to the appropriate relay channel on the 50-pin header or 37-pin D-sub connector. Twenty-four enunciator LEDs, one for each relay, light when their associated relay is activated. Because there is a D-sub 37-pin connector on the board, the user may use it to interface to any TTL output board. In other words, the user may use it as a general purpose solid state relay output board.
