Filter
Frequencies
The module uses a digital filter that provides high frequency noise rejection for each
input signal. The filter for each channel is programmable allowing you to select from six
different filter frequencies:
• 4.17 Hz
• 10 Hz
• 16.7 Hz
• 19.6 Hz
• 62 Hz
• 470 Hz

Hardware
Features
Each module requires a terminal base unit. Terminal base units are connected together to
form the backplane for the system. Each base unit contains terminals for field
terminations. Field terminations are wired as differential inputs with the exception of
