CHANNELS PER CARD: 10.
FUNCTIONS: Volts, Amps.
CONTACT CONFIGURATION:
Voltage Mode: Single pole break-before-make for signal HI input. Guard
is common for all 10 channels and output.
Current Mode: Single pole break-before-make for signal HI input. Signal
LO is common for all 10 channels and output. When a channel is off,
signal HI input is connected to signal LO via a relay. All channels con-
nect to signal LO in a make-before-break configuration between
channel closures so that the current path is never interrupted.
All relays open when power is off.
SCAN SPEED:
1.5 channels/second with default settings.
1, 2
43 channels/second maximum speed.
