The Endevco model 2775B signal conditioner is a rack-mountable, single-channel PE/Isotron amplifier. The unit accepts inputs from PE, Isotron or remote charge converters (RCCs) with a wide full-scale input range covering from 0.01 to 100,000 EU.
Setup can be configured manually on the unit's front panel or via an RS-232 computer interface and included controlling software. Up to six 2775B Signal Conditioners can be installed in a 19" Endevco model 4948A rack.
The signal conditioner provides three standard outputs:
- AC output voltage proportional to input, programmable from 1 to 10 volts
- DC output voltage proportional to input, programmable from 1 to 10 volts
- A servo output with a programmable mV/EU setting from 0.1 to 1000 mV/EU, with maximum amplifier gain of 1000
The model 2775B signal conditioner accepts two optional filter modules. Filter Module 35771 is a plug-in, 4-pole, Butterworth filter that is jumper-configurable for high-pass, low-pass or band-pass filtering. Filter Integrator Module 35818 provides a capability for single or double integration of the input signal, giving a velocity or displacement output.
Additional 2775B features include switchable isolation, a gain range of 0 to 10,000, and a wide frequency response of 120 KHz bandwidth (-3 dB corner).
Model 35933A software is included with the unit and provides an RS-232 interface for the Windows-based controlling software to configure up to 20 model 2775B units.
The aluminum-encased unit weighs approximately 4 pounds and measures 5.0 x 2.78 x 13 inches (12.7 x 7.1 x 33 centimeters).
