The ADLREL-8×16 relay matrix board can be stacked up to eight boards high for a total matrix size of 8×128 (1024) relay switches. Relay control is via an mPCIe FPGA controller that can control up to eight stacks of ADLREL-8×16 relay cards.
The ADLREL-8×16 conforms to the PC/104 footprint with external power and data (cable ADLREL-CBL1). Each stack requires discrete 3.3VDC power to the top of each stack and a control data cable from the 40-pin mPCIe controller. Board to board spacing is 0.75” to accommodate the 1A, 20W reed relays. A 0.5A relay option is available which allows for 0.6” PC/104 board spacing.
Coupled with an ADL Intel Atom or Intel Core PCIe/104 CPU board, a complete solution can be accomplished in a very compact and rugged design.
