Keithley 7061, 7059 Datasheet
7059 Low Voltage Scanner Card
10-Channel, 2-Pole
For low-level transducer switching, the Model 7059
is designed to reduce errors due to thermocouple
effects in the contacts (<1µV maximum) and
ensure that high isolation (10
between input signals. It will switch any one of ten
signals to one output or switch one signal to any
one of ten outputs. Switch settling time is less than
2 milliseconds.
• <1µV contact potential
• 200V switching

The Model 7061 was designed with a 6-volt supply,
ground trace, and a grid pattern of plated-through
holes on 0.1 inch centers for mounting special
relays or circuits. Relay drive lines from the scanner mainframe can be used for control. A supplied
ribbon cable assembly extends the relay drive lines
beyond the enclosure for easy access to relay cards
for troubleshooting.
RELAY DRIVE LINES: 350mA sink.
HARDWARE SPACE: 15/16 inch, maximum height a component
can protrude from the universal adapter card and fit in the
7001 or 7002 mainframe.
HOLE SIZE: 0.062 inch diameter.
HOLE SPACING: 0.1 inch centers
RIBBON CABLE: 2 ft length with connectors preassembled.
STRAIN RELIEF CLAMP: Assembly provided.
OPERATING CODES: Provided in manual.
