44471D 20-Channel GP Relay Module
The Agilent 44471D GP Relay module provides 20 independent Single
Pole - Single Throw (SPST, Form A) latching relays. Typically used as an
actuator assembly, its low thermal characteristics make it ideal for
independent (non-multiplexed) signal switching.
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 1
amp 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.
Specifications for the 44471D are given on page 335.
44471D Simplified Schematic
A simplified schematic is shown below. The 44471D GP Relay Module
consists of 20 independent SPST (Single Pole - Single Through) relays.
Channels are numbered as 00 through 19 (CH00 through CH19).
