Allen-Bradley 1746-NI16V Analog Input Module Logic Controller Module

Description of 1746-NI16V

The 1746-NI16V is an analog input module from the SLC 500 series of Allen-Bradley. 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.

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 Allen-Bradley with variety of lengths. These pre-wired cables may be partnered with Allen-Bradley 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.

About 1746-NI16V

The 1746-NI16V belongs to the Allen-Bradley SLC 500 Analog Input Module series. The Allen-Bradley 1746-NI16V SLC 500 Analog Input Module communicates with an SLC 500 processor through a parallel rear-facing interface. This module receives its electrical power from the system’s central SLC 500 power supply via a backplane. The acceptable operating temperature range of the Allen-Bradley 1746-NI16V SLC 500 Analog Input Module runs from -25 degrees to 60 degrees Celsius or -13 degrees to 140 degrees Fahrenheit. However, the non-operating temperature range runs all the way from -40 degrees to 85 degrees Celsius or -40 degrees to 185 degrees Fahrenheit.

The ratio of the Allen-Bradley 1746-NI16V SLC 500 Analog Input Module runs from a minimum of 5% relative humidity to a maximum of 95% (Non-condensing). The backplane current at 5 Volts is 125 milliamperes. At 24 Volts, this module's backplane current is 75 milliamperes. The backplane power consumption of this module is a maximum of 2.425 Watts. This will be 0.625 Watts at 5 Volts Direct Current and 1.8 Watts at 24 Volts Direct Current. Removing or inserting a module while any power source is connected may lead to dangerous electrical arcing. For this reason, please remember to disconnect all sources of power before removing or inserting this module. The Allen-Bradley 1746-NI16V SLC 500 Analog Input Module features a total of 16 separate input channels and a total resolution of 16-bits. The common mode voltage range of this module is +/- 10.25 Volts compared with the analog common terminal.
