Signal Conditioning Amplifier
FEATURES
• Plug-in amplifier design; amplifiers are removable from the
front panel without rear access
• Constant-voltage or constant-current excitation; 0.5 to 15V
or 0.5 to 30mA; selectable by single internal switch
• Calibrated gain from 1 to 3300; adjustable front-panel gain
switch and calibrated front-panel ten turn potentiometer
• Front-panel monitoring of: ±10V output; excitation;
automatic balance status; and amplifier balance
• Automatic wide range-bridge balance with battery backup
to retain balance in power-off condition
• Input coupling; selectable ac or dc by internal jumpers
• Fully grounded input amplifier; ±350Vdc or peak ac
common-mode operating voltage
• Full-power bandwith of 100kHz at all gain settings; slew
rate of 6.3V/µs
• Built-in four-pole Bessel low-pass filter with cutoff
frequencies of 1Hz, 10Hz, 100Hz, 1kHz and 10kHz;
front-panel frequency selection switch
• Two simultaneous buffered outputs; ±10 V and tape
1.0Vrms; will drive up to 0.15µF without instability
• Stable, proprietary bridge completion module for quarter-
and half-bridge 120- and 350-ohm strain gage and
transducer circuits
• 120-ohm dummy easily configured for 1000-ohm
completion
• Built-in shunt calibration circuits; internal user-selectable
configurations to provide two-point shunting of any bridge
component or two-point double shunt calibration of
transducers
• Optically isolated shunt calibration relays provided as
standard; built-in power supply for relay operation is
provided in ten-channel rack adapter and four-channel
enclosure
DESCRIPTION
The 2200 Signal Conditioning System incorporates, as
standard, all the features necessary for precise conditioning
of strain gage and transducer inputs in the most severe
operating environments.
The 2210A Amplifiers plug in from the front of the ten-
channel 2250A Rack Adapter or four-channel 2260B
Portable Enclosure without removing the rear-panel input
connections.A single-channel adapter is also available.
Among the features of the 2210A Amplifier are isolated
constant-voltage/constant-current excitation, guarded input
structure with ±350V common-mode capability, ±10V and
tape outputs, automatic wide-range bridge balance and
four-pole Bessel low-pass filter.
Operating controls of the 2210A Amplifier are conveniently
arranged and clearly marked to minimize the possibility of
operator error. Constant-voltage or constant-current excita-
tion, calibration configuration, and other optional operating
modes are selected by easily accessible internal switches or
jumpers.
Typical 2200 System configurations are shown on the follow-
ing page. Complete specifications are given on page 18.
