8126 – 32 Channel TTL
The SeaDAC Lite 8126 provides 32 channels of buffered drive digital I/O. The
module addresses the 32 channels of I/O as four eight-bit ports, each programmable
as input or output. Use a standard 50-pin IDC ribbon cable to connect an industry
standard relay rack for PC based control and automation of equipment including
sensors, switches, security control systems, and other industrial automation systems.
A status LED lights when the 8126 is successfully communicating with a USB port.
