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

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 co ntro ller ’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. Refe r to your controller’s user

manual for more information. T he illustration below shows the module’s hardware

features.
