This unit
The Astronics/EADS/Racal 1260-20 and 1260-20B Power Switch Module is a C-size VXI switch card that distributes and controls AC line power, DC power supplies, and current sources through 20 independent Double-Pole Single-Throw (DPST) relays. Each channel operates independently or configures into custom switching networks, supporting maximum switching currents of 8 A at 250 VACrms or 5 A at 48 VDC. The module integrates relay coil current monitoring for confidence checking and includes mounting holes on each channel for series and shunt elements such as arc suppressors or filters.
