Advantech BB-232DRIO

Model 232DRIO provides a low-cost, easy to use solution for RS-232 serial port to discrete relay output applications. It offers one optically isolated input and two relay outputs. The General Purpose Control Module can be used to sense external ON/OFF conditions and to control a variety of devices. The 232DRIO includes a CD ROM with an instruction manual and demonstration programs written in QuickBASIC and C/C .
