Technical Specifications for 1746-NI16V

About 1746-NI16V

The 1746-NI16V is an analog input module from the SLC 500 series of AB. It features Sixteen (16) Voltage input channels compatible fir signal voltages of ±10V dc, 1 to 5V dc, 0 to 5V dc, 0 to 10V dc.

The 1746-NI16I is a component that occupies any available slot of an SLC 500 chassis. This module may be installed to the local chassis or in the expansion chassis, to any available slot except slot 0 of the main chassis as it reserved for the controller. This module occupies only single slot of the chassis. The main chassis is the chassis to where the controller is installed.



The user configurable signal and other parameters including input filtering are accessible with the use of the RSLogix 500 programming software. This software is a separately purchased software that requires a separate activation however, it is the common programming software for the entire SLC 500 product family.

This module has a replaceable terminal with part number 1746-RT25G. Pre-wired cables may also be used with this module. These pre-wired cables are manufactured by AB with variety of lengths. These pre-wired cables may be partnered with AB terminal blocks such as 1492-AIFM8-3 and 1492-AIFM16-F-3. When these are used, errors caused by manual wiring may be eliminated as the pre-wired termination system present proper color coding of wires and easy to manage terminal block assembly.

This module is UL listed, C-UL approved and CE compliant for all applicable directives. It is also approved for use in Class I Division 2 Hazardous Environment.

The Allen Bradley 1746-NI16V is an Analog Input Module from the SLC 500 series. The 1746-NI16V communicates with an SLC 500 processor through a parallel rear-facing interface, and receives power from the SLC 500 power supply via a backplane. Its operating temperature lies between -25 to 60 degrees Celsius (-13 to 140 degrees Fahrenheit), while its nonoperating temperature lies between -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The relative humidity of this module ranges from 5% to 95% without condensation. This module belongs to a Voltage Category of-10 to +10 Volts DC. The backplane current at 5 Volts is 125 mA; at 24 Volts, this module’s backplane current is 75 mA. The backplane power consumption of this module is 2.425 Watts max (0.625 Watts at 5 Volts DC and 1.8 Watts at 24 Volts DC). Removing or inserting a module while a power source is connected can cause an electric arc to occur; remember to disconnect the power before removing or inserting this module.

The Allen Bradley 1746-NI16V has 16 input channels and a 16-bit resolution. The common mode voltage range of this module is +/-10.25 Volts relative to the analog common terminal. Its input impedance is 20 Ω and its AIFM Connector is 25-pin D-shell.

This module has Standard Cable Lengths of 0.5, 1, 2.5, and 5.0 meters. It has a Gain drift of 15 ppm/degree Celsius, and the Input offset drift of this module is 90 mV/degree Celsius. The Input resolution of this module is 312 mV.
