Overview
What the Module Does The 1746-NO8I provides eight channels of current outputs, while the
1746-NO8V provides eight channels of voltage outputs. In both
modules, the current or voltage ranges are independently configurable
for each channel. These modules also provide new, advanced features
to make your control systems more dependable and flexible.
General Features And Benefits
•
Increased System Accuracy and Reliability
Both modules provide 8 output channels with 16-bit resolution.
They also provide 500V dc field-wiring-to-backplane isolation to
protect the processor and chassis. These modules maintain their
accuracy with fluctuating ambient temperatures, which is
important for crowded control cabinets.
•
Reduced System Costs
The 1746-NO8 modules provide a single-slot solution for
applications requiring up to eight outputs, so you don’t have to
buy more I/O than you need. Low-density (e.g. 4-channel)
modules may be replaced with 8-channel modules. Your ladder
logic is simplified as the modules provide channel ramping, limit
alarms, output clamping, and various data scaling options.
•
State-of-the-Art Performance
The modules provide 16-bits of resolution, excellent accuracy,
and require no field calibration. The modules are also software
configurable, providing programmable range settings, output
limits, and programmable safe states in case of a fault.
•
Class 1 or Class 3 Operating Mode
Class 1 operation (default) provides 8 input words and 8 output
words. Class 3 provides 16 input words and 32 output words.
Class 3 allows you to take advantage of the full set of features
available with this module.
