Allen-Bradley 1746-NI4 SLC™ 500 4-Channel Analog I/O Modules
Product Details:
Manufacturer : ALLEN BRADLEY
Product No. : 1746-NI4
Product Type : SLC 500 Analog I/O Module
The Allen-Bradley 1746-NI4 is a SLC 500 Analog I/O Module. This
Analog I/O Module has Four (4) non-isolated differential, voltage
or current selectable input channels. This module occupies single
slot of the SLC 500 chassis and compatible with fixed or modular
style hardware.
The Allen Bradley 1746-NI4 is an SLC 500 Four (4) Channel Analog
Input Module. It has user-selectable analog channels for voltage or
current to support multiple monitoring and control applications; it
has a 16-bit resolution and contains a removable terminal block
that provides connections analog input channel. This channel can be
connected as a differential input. There is a DIP that switches on
the circuit board to select the input or current voltage. The
Backplane current at 5 Volts of this module is 25 mA; at 24 Volts,
the current is 85 mA. Caution should be given to avoid connecting
the voltage source without the transmitter current, etc. to the
channel configured for current input. Incorrect module operation or
module damage may occur.
The 1746-NI4 has Standard Cable Lengths of 0.5, 1, 2.5, and 5.0
meters. The AIFM Connector of this module is 15-pin D-shell. The
Allen Bradley 1746-NI4 has Current Loop Input Specifications: the
input range is +/-20 mA (nominal) and +/-30 mA (maximum). The Input
impedance is 250 Ohms with a resolution of 1.22070 & µA per LSB
and an approximate Gain error drift of +/-67 ppm/degrees Celsius.
The overall accuracy at 25 degrees Celsius is +/- 0.365% of full
scale, +/- 0.642% at 60 degrees Celsius. The overall accuracy drift
is +79 ppm/degree Celsius of full scale. The 1746-NI4’s input
voltage range is +/-10 Volts DC -1 LSB. Its impedance is 1 mega
Ohms. The accuracy drift is +63 ppm/ degrees Celsius of full scale.
The Resolution is 305.176 & µV per LSB, with a Gain error drift
at +/- 57 ppm/degree Celsius. The Overall accuracy at 25 degrees
Celsius is +/-0.284% of full scale, and +/-0.504% at 60 degrees
Celsius.
The 1746-NI4 is an analog input module from the SLC 500 series of Allen-Bradley. It features Four (4) differential non-isolated input channels, individually selectable for voltage or current input. Selectable input signals ranges include -20 to +20 mA (or) -10 to +10V dc.
The module operates by converting the analog input signal via the
Delta–Sigma Modulation with range of -16,384 to +16,384 for Current
input and -32,768 to +32,767 for Voltage input. The converted data
may be processed with the use of Scaling algorithm to display the
measured process variable. Both method produces the same scaled
output.
This module is compatible of being used with a fixed or modular
hardware style SLC 500 controller. The Fixed hardware version of
SLC 500 comes with embedded I/O channels with limited expansion
capabilities. The modular hardware SLC 500 PLC features a fully
modular and customizable system.
This module has built-in LED indicator for indicating the status of
each channel and the overall status of the module’s operation. This
provides quick module diagnostic which may also be accessed via the
controller’s diagnostic interrupt. This system of reporting allows
faster troubleshooting period and increases the availability of the
module.
