N2261A 40-Channel GP Relay Module
The Agilent N2261A GP Relay Module contains 40 independent Single
Pole - Single Throw (SPST, Form A) latching relays.
If necessary, you can pair two N2261A modules to provide 2-wire
switching.
The N2261A can be operated in one of two modes: single channel
break-before-make (BBM) or multiple channels in a closed position.
A parallel switching feature makes the N2261A well suited for high
speed switching. The 40 2-wire relays on the N2261A can be separated
into four groups and up to 10 relays in the same group can be closed
simultaneously (parallel switching). The groups are: group 1 (channel 00
through channel 09), group 2 (channel 10 through channel 19), group 3
(channel 20 through channel 29) and group 4 (channel 30 through
channel 39). Additional information about parallel switching is given on
page 84.
Specifications for the Agilent N2261A are given on page 305.
N2261A Simplified Schematic
A simplified schematic is shown below. The N2261A contains 40
independent Single Pole-Single Throw (SPST, Form A) latching relays. A
channel refers to an individual relay on the module. Channels are
numbered 00 through 39 for the N2261A.
