SPEC-3723 Rev. A / September 2007 Page 1 of 3
Model 3723
Dual 1x30, High Speed Multiplexer Specifications
60 differential channels, long life reed relays
MULTIPLEXER CONFIGURATION: Two independent 1x 30 2-pole Multiplexers. Banks can be connected together
via relay creating a single 1 x 60 Multiplexer. Banks can be isolated from the backplane by relays. Card can be
configured for 1,2 and 4 wire.
CONTACT CONFIGURATION: 2 pole form A.
CONNECTOR TYPE: Two 78 pin male D-shells.
Model 3723-ST screw terminal option:
#22AWG typical wire size with .062 inch O.D 124 conductors maximum. 16 AWG maximum wire size with .092
inch O.D. 36 conductor per card maximum.
MAXIMUM SIGNAL LEVEL: 200V DC or RMS, 1A switched (1.25A carry), 15W.
COMMON MODE VOLTAGE: 300V DC or RMS between any terminal and chassis.
