44471A 10-Channel GP Relay Module

44471A 10-C h an n el G P R elay M odu le
The Agilent 44471A GP Relay Module provides 10 independent Single
Pole - Single Throw (SPST, Form A) latching relays. The individual
relays on this module are rated for a maximum open circuit voltage of
250 volts dc or ac rms. Maximum current per relay is 2 amps dc or ac
rms, and maximum power per relay is 60 watts dc or 125 VA ac.
Maximum closed channel resistance is less than 2 Ω.
The 44471A exhibits low thermal characteristics, which make it ideal for
independent (non-multiplexed) signal switching. It can be operated in
either single channel break-before-make (BBM), or multiple channels
closed at the same time.
Specifications for the 44471A are given on page 333.
44471A Simplified Schematic
A simplified schematic is shown below. The 44471A consists of 10
independent Single Pole-Single Throw (SPST, Form A) relays. Channels
on the 44471A are numbered as 00 through 09 (CH00 through CH09).
