Model 6521 Low Current Scanner
CHANNELS PER CARD: 10.
FUNCTIONS: Amps. H H
CONTACT CONFIGURATION: IN 1
L




IN 2...9
Current Mode: Single pole break-before-make for signal HI input. Signal OUT L
LO is common for all 10 channels and output. When a channel is off,
signal HI is connected to signal LO via a relay. All channels connect to
G
signal LO, in a make-before-break configuration between channel clo- H
sures so that the current path is never interrupted. IN 10
L
All relays open when power is off.
