3732
Quad 4×28, Ultra-High Density,
Reed Relay Matrix Card
448 one-pole crosspoints with bank configuration and backplane connection relays
MATRIX CONFIGURATION: Four banks, each with 4 rows by
28 columns of reed relays. Bank configuration and analog
backplane relays are included for additional matrix configura-
tions. Banks can be connected together via relays creating
dual 4×56 matrices or a single 4×112 matrix. Row expansion
is available using optional screw terminal accessories.
CONTACT CONFIGURATION: Single-pole form A.
CONNECTOR TYPE: Two 78-pin male D-shells.
MODEL 3732-ST-R SCREW TERMINAL OPTION: Provides ter-
minal block access and column jumper blocks for extended
row configurations including Dual 8×28 (1W), Single 8×28
(2W), and Single 16×28 (1W).
Typical Wire Size: #22 AWG with 0.062 inch O.D.; 88 con-
ductors per card maximum.
Maximum Wire Size: #16 AWG with 0.092 inch O.D.; 44
conductors per card maximum.
MODEL 3732-ST-C SCREW TERMINAL OPTION: Provides
terminal block access for Quad 4×28 (1W), Dual 4×28 (2W),
Dual 4×56 (1W), Single 4×56 (2W), and Single 4×112 (1W)
matrix configurations.
Typical Wire Size: #22 AWG with 0.062 inch O.D.; 88 con-
ductors per card maximum.
Maximum Wire Size: #16 AWG with 0.092 inch O.D.; 44
conductors per card maximum.
MAXIMUM SIGNAL LEVEL: 200VDC or peak AC, 0.75A
switched (1.2A carry), 15W/15VA max. switch power.
COMMON MODE VOLTAGE: 200VDC or peak AC between any
signal path to a signal path or ground.
