Relay accessories to isolate load from dc output
Switch and sequence power and sense leads
dc output polarity reversal (59511A)
Agilent Technologies 59510A and 59511A are relay devices
designed for control from 66xxA and 603xA power supplies.
These power supply accessories can be configured to switch dc
power to multiple test fixtures, or can be used to provide an extra
measure of protection in the case of a fault condition where emer-
gency shutdown is required. The 59511A has all the features of
the 59510A, and also provides relays for polarity reversal. Each
box switches one power supply output. They can be used with any
dc power supply which falls within the voltage and current limits.
The internal microprocessor sequences the switching of power
and sense leads. This protects the load by minimizing possible
voltage overshoots. When used with Agilent system power sup-
plies that have been configured appropriately, the relays can be
controlled through the power supply GPIB port. For other applica-
tions, the 59510A and 59511A are controlled through a TTL port.
Both relay accessory models can be mounted on any one of three
sides to a flat surface with the PEM fasteners provided. The Rack
Mount Kit (Option 850) eases mounting behind the power supply
or towards the front of the equipment rack.

Options
Opt 850
Rack Mount Kit (side-by-side mounting of two
units requires two kits)
Opt 910 Extra Operating and Service Manual
Not for use on 6680A, 6681A, 6682A, 6683A,
6684A, or 6035A.
The relay accessories can be mounted behind power supplies
using the Option 850 Rack Mounting Kit.
The device can be orientated in any horizontal position on the
tray. The orientation shown can be used in shallow racks which
do not have space to run cables from the relay accessory towards
the rear of the rack.
