The OME-DB-24R consists of 24 form C, electromechanical relays for efficient switching of load by programmed control. The contact of each relay can control a 0.5 A /110 V load or 1 A/24 Vdc. The relay is energized by applying a 5 V signal to the appropriate relay channel on the 50-pin OPTO-22 compatible connector or 37-pin D-Sub connector. Twenty-four enunciator LED’s, one for each relay, light when their associated relay is activated. To avoid overloading your PC ’s power supply, this board needs a +12 Vdc or +24 Vdc external power supply.

On page 26 of the manual, the numbering on the right side of the 37-pin D-sub connector seems non-standard. Should standard D-sub numbering (1-19, bottom to top) be used?

Do you offer a ACAD download of the 24-Channel Relay Output Board?

Asked by: Ron T
Thank you for your question. We do not provide a Cad drawing just dimensions in the manual you can download from the website.

Does this board require an external 5V power supply in addition to 12/24V? I am unsure if the +5V lines shown on page 26 of the manual are for supply or reference.

Asked by: P126
Hello Regarding your question, if you are referring to the +5VDC on the board, that is to specifically power up the relays on the board, whereas the 12VDC/24VDC connection is to power up the board itself.

The manual doesn't provide mounting hole spacing, only outer board dimensions. Can you provide the hole spacing since there are no CAD models?

Asked by: dstix747
Thank you for your questions. Diameter is 4mm for the holes. Spacing is 210mm and 122mm.
