1746-SIM Input
Simulator
The 1746-SIM Input Simulator is designed for use on 16-channel 24V dc sinking and
sourcing modules with removable terminal blocks, including 1746-IB16, 1746-ITB16,
1746-IV16, 1746-ITV16, and 1746-IN16 modules. The input simulator provides 16
switches for simulating inputs to the SLC 500.
1746 Analog I/O
Modules
Analog I/O modules feature user-selectable voltage or current inputs, backplane
isolation, removable terminal blocks, and diagnostic feedback.
The 1746-NI4, 1746-NIO4I, and 1746-NIO4V input channels are filtered to reject high
frequency noise and provide 14- to 16-bit (range-dependent) resolution.
All 4-channel analog output modules provide 14-bit resolution and a 2.5 ms
conversion rate.
The 1746-FIO4I and 1746-FIO4V modules have less input filtering and can sense
more rapidly changing inputs. However, their input resolution is only 12-bit. Because
the input filter on the 1746-FIO4I or 1746-FIO4V module may pass more electrical
noise, you should thoroughly ground and shield the input transducer, its power
supply, and cables.
The 1746-NI8 module provides high accuracy and fast analog signal conversion. The
1746-NI8, 1746-NI16I and 1746-NI16V modules are high density analog input
modules that are software configurable.
The 1746-NO8I (current output) and 1746-NO8V (voltage output) modules are high
density, analog output modules that provide 8 individually configurable output
channels with 16-bit resolution.
