The HP/Agilent 59510A is a remote-controlled relay accessory that expands switching capability for compatible DC power supplies and test systems. It isolates loads from DC outputs, switches power and sense leads, and supports TTL or GPIB control. The unit operates across three power ranges: 200 V at 20 A, 120 V at 30 A, and 48 V at 60 A. With floating voltage isolation to 500 Vdc and typical settling times of 440 ms (connect) and 160 ms (disconnect), it integrates directly into automated test environments.
