Overview
OV-4
CR9051E Fault Protected 5 V 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 CR9000X is powered off. The CR9051E is recommended
over the CR9050E for applications where fault voltages beyond
±
9 V could
come in contact with the inputs, or when the CR9000X could be powered off
while still connected to sensors that have power applied to them. The
CR9051E supports the same instruction set as the CR9050.

CR9052DC Anti-Alias Filter Module with DC Excitation
The CR9052DC is a high-performance anti-alias filter module that extends the
capability of the CR9000X Measurement and Control System. The module
includes six anti-aliased analog measurement channels with differential input
ranges from ±20 mV to ±5 V. Each input channel has current and voltage
excitation options. Measurement rates up to 50 kHz per channel are possible.

CR9052IEPE Anti-Alias Filter Module with DC Excitation
The The CR9052IEPE module allows direct connection of Internal Electronics
Piezo-Electric (IEPE) accelerometers and microphones to CR9000- or
CR9000X-series dataloggers. Each CR9052IEPE includes six channels. Each
channel has a BNC connector, an open circuit indicator LED, and a short
circuit indicator LED which can indicate if the channel is over-or under-driven.
Each channel has a built-in constant current source which is software
programmable to 0, 2, 4, or 6 mA.
