OV1.2 Measurement Modules
CR9050(E) Analog Input Module
The CR9050(E) Analog Input Module has 14 differential or 28 single-ended
inputs for measuring voltages up to
±
5 V. Voltages exceeding
±
9 V may cause
errors on other channels. An on-board PRT provides the reference temperature
for thermocouple measurements, while a heavy copper grounding bar and
connectors combine with the case design to reduce temperature gradients for
accurate thermocouple measurements. Resolution on the most sensitive range
is 1.6
µ
V.

CR9051E Fault Protected 5V Analog Input Module
The number of channels and measurements are the same as for the CR9050
Analog Input Module. Each input channel is fault-protected so as to permit
over-voltages b50 V and –40 V without corruption of measurements
on other input channels. All the CR9051E input channels become open
switches when the CR9000 is powered off. The CR9051E is recommended
