The Model 7054 is a high voltage scanner card that switches
signal levels up to 1000V, 0.5A or 10VA peak (10mA at 1000V)
for resistive loads only. Each of the 10 channels on the
card consists of a single-pole, Form A (normally open) relay
with a common guard connection and a fused input. The output
connection and the input connections have quick disconnect
screw terminals with a maximum allowable wire size of No. 18
Single-pole switching is done in less than 20msec exclusive
of the mainframe, and the specified contact life is 10s
closures with cold switching and 106 closures at maximum
signal levels. Contact resistance is less than lfi. The
relay drive current is 50mA/relay.
The Model 7054 is field installable in an appropriate
Keithley scanner mainframe (e.g. Model 705 or Model 706).
With the isolation between each channel being greater than
1012fl and less than lOpF, each channel is well insulated
from cross channel noise and interference.
