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.
