Rockwell Automation 1746-NI8 SLC 500 Analog Input Modules User Manual - Manual (Page 12)

1–2 Overview
Publication 1746Ć6.8 - April 1997
Important: Status words are only available when the module is
configured for Class 3.
Hardware Features
The module fits into any slot, except the processor slot (0), in either
an SLC 500 modular system or an SLC 500 fixed system expansion
chassis (1746-A2).
The module contains a removable terminal block providing
connection for eight analog input channels, which is specifically
designed to interface with analog current and voltage input signals.
The channels can be wired as either single-ended or differential
inputs. There are no output channels on the module. Module
configuration is done via the user program. There are DIP switches
on the circuit board for selecting voltage or current input.
