The IC694ALG233 input module is an analog current input module. The input module provides 16 single-ended input channels. When installing the IC694ALG233 input module in a dangerous place, you must turn off the power before replacing or connecting cables. In addition, modules should not be connected to or disconnected from the PLC unless the main system power is turned off. The IC694ALG233 input module draws 120 mA current from the +5 V DC bus on the system backplane. In addition to loop current, the IC694ALG233 input module draws 65 mA current from a 24 V DC rated external power supply. The IC694ALG233 input module can withstand the external voltage ripple of 10%. The voltage range of the external power supply is 20 to 30 volts DC. The rated input low-pass filter response is 23 Hz

There are 16 channels on the IC694ALG233 input module, each of which can be configured with the following input ranges: 0 to 20 mah, 4 to 20 mah enhanced, and 4 to 20 mah normal. The upper and lower alarm limits can also be configured via software. For an enhanced current range of 4 to 20 mA, a lower alarm limit can be configured to detect input currents between 4 and 20 mA. This feature can be used to provide line break detection in enhanced current rating applications ranging from 4 to 20 mA. The IC694ALG233 input module also reports the module status and external power supply status to the system CPU using the assigned program reference address. The IC694ALG233 input module can be installed in an I/O slot with a serial connector. The IC694ALG233 input module supports hot swap. The firmware on the IC694ALG233 input module can be upgraded to enable new features.
