1. Introduction
The DB-24PR/DB-24PRD is a 24-channel power relay output board which
consists of 8 Form C and 16 Form A electromechanical relays for efficient
load switching. The contact rating of each relay is 5 A at 250 VAC or 5 A at
30 VDC. These relays can be switched to ON by applying a 5 V signal from
an I/O Card in the PC to the appropriate relay channels. The DB-24PR/DB-
24PRD daughter board contains a single 50-pin OPTO-22 compatible
connector, and a single 37-pin D-sub connector or a single 20-pin flat cable
connector. The 24 onboard LEDs indicate the output status of the relays,
illuminating when their associated relay is activated. To avoid overloading
your PC’s power supply, this board requires either a +12 VDC or a +24
VDC external power supply.
