High Current Relay ISA Card

GT6020 - Marvin Test Solutions, Inc.

The GT6020 is a 20-channel, high-current relay board that plugs directly into any 8-bit I/O slot of an IBM compatible computer.
The GT6020 provides an additional 12 transistor-driven channels for external relays in the form of open-collector transistors providing up to 500 mA of sink current.. These outputs may be used to drive external relays for a total of 32 relay controls per each GT6020 card. A 78 pin D connector provides access to 20 sets of NC (normally closed), CO (common), and NO (normally open) contacts.
