No Input Impedance <250 Ω for current external reference source required >220 kΩ for voltage (-INI4vi only) Input Overcurrent Protection 70 mA non-continuous The 1746sc-INO4i provides four isolated channels of current, while the 1746sc- Input Overvoltage Protection 50 VDC, continuous (-INI4vi only) INO4vi provides four isolated channels of current or voltage (in any combination). Common Mode Rejection 99 dB @ 1 kHz, 25°C In both modules, the voltage and/or current ranges are independently configurable for each channel. These modules provide new, advanced features to make your Normal Mode Rejection 98/98 dB @ 50/60 Hz control systems more dependable and flexible. Backplane Current Required 1746sc-INI4i: 460 mA @ 5 V & 0 mA @ 24 V typical 1746sc-INI4vi: 570 mA @ 5 V & 0 mA @ 24 V typical Increase System Reliability Both modules provide 750 Vdc channel-to-channel isolation, which means no Thermal Dissipation 3.25 Watts, maximum electrical noise crosstalk (resulting in a high usable resolution—something to Update Time (minimum) 14 ms for 4 current inputs with 500 Hz filters consider with a high-performance, 16-bit module). They also provide 750 Vdc 18 ms for 4 voltage inputs with 500 Hz filters field-wiring-to-backplane isolation to protect the processor and rack. These Step Response Time (typical) 8 ms with 500 Hz filters; 67 ms with 60 Hz filters modules feature onboard temperature compensation to maintain their accuracy Environmental Conditions with fluctuating ambient temperatures, important for crowded control cabinets. Operational Temperature 0° to 60°C (32° to 140°F) Storage Temperature -40° to 85°C (-40° to 185°F) Reduce System Costs Because isolation is built into these modules, you can improve system accuracy Relative Humidity 5 to 95% (non-condensing) while saving hundreds of dollars on system installation costs. Expensive, external Certifications UL/CUL (Class I, Div 2, Groups ABCD) and CE isolation blocks are simply not required. They also provide a single-slot solution Recommended Cable Shielded, twisted-pair, Belden 8761 for applications requiring up to four, mixed analog outputs, so you don't have to buy more I/O than you need. Get State-of-the-Art Features These modules incorporate proprietary Allen-Bradley technology, so they operate and perform like an Allen-Bradley product. They also provide 16-bits of resolution, user-programmable range setting, continuous auto-calibration (no field calibration), software configuration, programmable output limits, and programmable safe states in case of a fault.
