DESCRIPTION
The 6035 input module has eight channels of programmable transducer signal conditioning amplifiers and digitizer. Each channel has programmable voltage excitation, bridge completion and balance, programmable gain instrumentation amplifier, four-pole low pass filter and sample and hold amplifier. Channel outputs are multiplexed and digitized to 16 bits then provided to the 6000 data bus. In addition to the digitized output, each channel has an analog output providing a means to monitor or record each channel.
The 6035 is used with ¼, ½ and full bridge transducers, potentiometers and low-level voltage signals. It is particularly suited to strain gages. A shielded four-wire input provides signal and excitation connections to the transducer. Excitation is programmable from 0 to 12 Volts for each channel. Individual excitation
regulators and careful routing of power traces and grounds results in less than 0.01% effect due to loading or a short on another channel. A calibration mode is provided to measure the excitation voltage.
| Unless noted, specifications apply to each channel individually |
| Input |
Two to four wires with shield with completion resistors for quarter, half and full bridge transducers.
Input connector is 50-pin Type D Subminiature. |
| Excitation |
0 to +12 Volts in 1 ±0.1% Volt steps (same voltage for 8 channels), 70 mA per channel. Stability is ±0.01%,
line and load regulation are ±0.1%. Open circuit and short circuit alarms. Short on one channel does not
affect other channels. |
| Balance |
Automatic to ±0.05% of range ±1 mV RTO. Stability is ±0.02%, ±0.005%/°C. User adjustable balance range. |
| Input Range |
±2 mV to ±10 Volts full scale. Input protected to ±50 Volts. |
| Calibration |
Voltage substitution with attenuation of 1, 0.1 and 0.01. Single-step resistive shunt calibration. |
| Gain |
Programmable from 1 to 5,000 in 1, 2, 3, 5, 10 steps with ±0.05% accuracy. |
| Static Accuracy |
Typically ±0.02% for gains 1 to 1,000 after calibration. |
| Common Mode |
60 dB plus gain in dB up to 106 dB, DC to 60Hz for ±10 Volts. |
| Bandwidth and Filter |
1 kHz bandwidth. Four-pole low-pass filter with plug-in modules for 1 Hz to 1 kHz, 10 Hz supplied. |
| Sampling |
Up to 10k samples per second per channel. Time correlation is ±50 nS. |
| ADC |
16-bits, two's complement output. |
| Analog Output |
±3 Volts full scale. |
