Spectrum Controls 1746sc-INO4vi - Manual (Page 11)

Overview And Specifications
The 1746sc-INO4i provides four isolated channels of current outputs,
while the 1746sc-INO4vi provides four isolated channels of current or
voltage outputs (in any combination). In both modules, the voltage and/or
current ranges are independently configurable for each channel. These
modules also provide new, advanced features to make your control
systems more dependable and flexible.

Benefits
Increased System Accuracy and Reliability
Both modules provide 750 Vdc channel-to-channel isolation, which
means no electrical noise crosstalk between channels (resulting in a high
usable resolution). They also provide 750 Vdc field-wiring-to-backplane
isolation to protect the processor and rack. These modules even feature
onboard temperature compensation to maintain their accuracy with
fluctuating ambient temperatures, which is important for crowded control
cabinets.
Reduced System Costs
Because isolation is built into these modules, you can improve system
accuracy while saving hundreds of dollars on system installation costs.
Expensive, external isolation blocks are simply not required. They also
