Information About 1746-IV16

The Allen-Bradley 1746-IV16 is an SLC 500 discrete input module. This module features Sixteen (16) sourcing input channels, ideally used for interfacing electrical signaling devices such as switches, auxiliary contacts, sensors and other devices that provide binary or ON/ OFF signal states.

The 1746-IV16 supports source wiring configuration. Commonly, input devices carry the signal voltage and sends this voltage towards the input module via sink wiring configuration. In some scenarios, some electrical signaling devices does not carry an input signal voltage. This is when the 1746-IV16 may be used wherein, the module itself provides the signal voltage to the loop then returns this input channels of the module when the device signal state changes.

Each channel of the 1746-IV16 are designed to be operated at a nominal voltage of 24VDC however, accepts voltage range of 10-30 VDC. Additionally, each requires a nominal input current of 8 mA at 24VDC. The maximum on-state input voltage is 5.0 VDC and the maximum off state input current is 1 mA. Each channel exhibits a maximum signal delay time of 8 ms for both ON to OFF and OFF to ON transitions.

The 1746-IV16 is a single slot wide module that directly installs to any available slot of the 1746 chassis. It may be used as a local I/O module or remote I/O module. It comes with a 16 LED status indicators, each assigned to monitor the state of the input channels. It also comes pre-installed with a removable terminal block that allows modular wiring and simplified module replacement in the event of module malfunction.

The 1746-IV16 has a maximum off-state current and voltage of 1 mA and 5 Volts DC. It has a nominal input current of 8 mA at 24 Volts DC and a maximum power dissipation of 3.6 Watts. It finds applications in general-purpose DC inputs in an SLC 500 system. The 1746-IV16 module is responsible for receiving and storing digitally-converted analog data into its data image table to be retrieved by all the modular and fixed SLC 500 processors. It supports connections from up to 8 sensors or actuators for various applications. The 1746-IV16 module comes with removable terminal blocks, eliminating the need to disconnect any of the wires and making module replacement easy. It also includes filter circuitry and optical coupling for signal noise reduction. The 1746-IV16 module input values can be easily accessed by SLC 500 processors that use Ladder Logic programming. Troubleshooting becomes easier with LED indicators that show input status ratings. The SLC 500 system uses a sharing-based hardware platform which includes various combinations of digital and analog I/O, thus saving cost and space. The 1746-IV16 is intended for use in an environment with a 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) temperature range and a 5 to 95% noncondensing relative humidity range.

Frequently Asked Questions about 1746-IV16
Question: What is the 1746-IV16?
Date Update:12/06/2025
Answer:

The 1746-IV16 is an Analog Input Module from Allen-Bradley, specifically designed for the SLC 500 series PLC. It is used to interface analog sensors (such as temperature, pressure, or flow sensors) with the PLC system. This module provides 16 input channels for analog signals, typically supporting 0-10V DC or 4-20mA input ranges.

Question: Where can I find the manual for the 1746-IV16?
Date Update:12/06/2025
Answer:

The manual for the 1746-IV16 module can be obtained from the Rockwell Automation website. You can find the manual by:

  1. Visiting the Rockwell Automation or Allen-Bradley support site.
  2. Searching for 1746-IV16 or Analog Input Module.
  3. Navigating to the Product Documentation section to download the user manual, which will include wiring diagrams, configuration details, and troubleshooting guidelines.
Question: What types of input signals are supported by the 1746-IV16?
Date Update:12/06/2025
Answer:

The 1746-IV16 module supports two main types of input signals:

  1. Voltage Input (0-10V DC): This input type is used for sensors that provide a voltage signal proportional to the measurement, such as temperature sensors, pressure transducers, or flow meters.
  2. Current Input (4-20mA DC): This input type is commonly used for sensors with a current output, often used for industrial process control applications like pressure or temperature measurements.

You need to configure the module properly in the PLC program to match the input type used in your system.

Question: How do I configure the 1746-IV16 in the PLC program?
Date Update:12/06/2025
Answer:

To configure the 1746-IV16 in an SLC 500 PLC program:

  1. Add the module to the I/O configuration in the RSLogix 500 programming software.
  2. Assign addresses for the input channels in the program. For example, each analog input channel will be mapped to a specific memory location in the PLC (e.g., N7:0 for the first input channel).
  3. Scaling: Set up the scaling for the analog inputs to convert the raw input values into engineering units. This is done by defining the input range (e.g., 0-10V or 4-20mA) and scaling it to a meaningful value (e.g., temperature in degrees Celsius or pressure in PSI).
  4. Configure the input type (Voltage or Current) based on your application and sensor type.

Consult the RSLogix 500 programming manual and the 1746-IV16 user manual for specific details on setting up the configuration and scaling parameters.

Question: What is the resolution of the 1746-IV16 module?
Date Update:12/06/2025
Answer:

The 1746-IV16 module has a 12-bit resolution for each input channel. This means the module can represent the analog input signals with 4,096 discrete levels (2^12) for each channel, providing accurate readings and measurements within the input range.
