Section 1.3
Filter
Frequencies
The module uses a digital filter that provides high frequency noise rejection for the input
signals. The filter is programmable, allowing you to select from five different filter
frequencies for each channel:
•
28.5 Hz
•
50 Hz
•
60 Hz
•
300 Hz
•
360 Hz
Section 1.4
Hardware
Features
The module contains a removable terminal block. Channels are wired as differential
inputs (i.e. each channel will have a dedicated ground).
Note: A jumper must be installed on the terminal block between CH- and CH-iRtn for
all current input ranges.
Module configuration is done via the controller’s programming software. In addition,
some controllers support configuration via the user program. In either case, the module
configuration is stored in the memory of the controller. Refer to your controller’s user
manual for more information. The illustration below shows the module’s hardware
features.
