78-Pin D-Type Female With Backshell
78-Pin Female D-type Connector, Density and a Half, with Backshell, Solder Bucket
The 50-411A is the perfect solution for driving external relays from a PCI slot.
The card provides 64 channels of low side switching for external
relays. Users need to simply connect a positive voltage source
to one terminal of a relay coil and the other terminal to an output
of the 50-411A. Each output is capable of sinking up to 1A of
continuous current.
Outputs have current, thermal and overvoltage protection. The thermal and current
limit circuits protect the output from failure even when directly connected to
voltages up to 30V.
