1756-IF16H Allen Bradley Rockwell Analog Input Module

Product parameters

Module type:

The ControlLogix analog input module supports the HART (Highway Addressable Remote Transducer) protocol.

16-channel differential input, specially designed for current signals.

Input signal range:

Current input: 0-20 mA or 4-20 mA.

Resolution:

16 to 21 bits, providing high-precision signal conversion, suitable for applications that require precise measurement.

Number of input channels:

There are 16 differential input channels, each equipped with an independent HART modem, supporting HART protocol communication.

Analog-to-digital Conversion (ADC)

The Successive Approximation method is adopted for the conversion from analog signals to digital signals.

Data storage format: IEEE 32-bit floating-point number, left-aligned, 2's complement (Integer mode).

Isolation and Protection

Isolation voltage: 50V (continuous), providing isolation between channels and enhancing anti-interference capability.

Overvoltage protection: Supports up to 8V DC to protect the module from electrical anomalies.

Module filter

Built-in module-level filter to reduce input signal noise (approximately -3 dB or 0.707 times amplitude).

Supports real-time sampling (RTS), and users can set the sampling frequency.

Working environment

Operating temperature: 0 to 60°C.

Installation method: ControlLogix frame (Chassis) installation, in conjunction with 1756-TBCH or 1756-TBS6H detachable terminal blocks (RTB).

Open casing, requiring a well-ventilated environment to maintain optimal performance.

Power supply and Power consumption:

Backplane power consumption: approximately 2.3W (depending on the configuration).

Compatible with ControlLogix 5570/5580 controllers.

Wiring requirements:

It is recommended to use a single-wire connection with a wire diameter of 0.33 to 2.1mm ² (22 to 14 AWG), shielded copper wire, insulation class of 105°C or higher, and a maximum insulation thickness of 1.2mm.

Certification and Standards

It complies with standards such as CE, CUL, GOST, KC, RCM and UL.

Others:

UPC code: 885630003412.

Function

High-precision signal conversion

Convert the analog current signal (0-20 mA or 4-20 mA) into a digital signal for processing by the ControlLogix controller, which is suitable for measuring physical quantities such as temperature, pressure and flow rate.

High resolution (16-21 bits) ensures precise data acquisition.

HART protocol support:

Each channel is equipped with an independent HART modem, supporting direct integration of HART devices, allowing for remote configuration, diagnosis and data acquisition, and reducing wiring requirements.

Support three data formats:

Analog Only.

Analog signal and HART main variable (Analog and HART PV).

Analog signal and HART by Channel data.

Fault and Condition Monitoring

It provides over-range/under-range detection and promptly alarms when the input signal exceeds the range.

Disconnection detection function: When a disconnection occurs, the input data is switched to the scaling value of the under-range and the fault position is set.

Detailed fault and status data are sent to the controller through the three-level Tag system (Tag Levels), facilitating precise monitoring by users.

Module filtering and real-time sampling

The module filter reduces signal noise and improves data quality.

The Real-time Sampling (RTS) function allows users to configure the scanning frequency of the input channel to adapt to different application requirements.

Flexible wiring and installation:

Use detachable terminal blocks (RTB) for on-site wiring, which is convenient for installation and maintenance.

Supports ControlLogix racks and can communicate with the controller via ControlNet or EtherNet/IP networks.

Application scenarios

Industrial Automation and Process Control

Oil and gas: It is used to monitor and control pipeline pressure, flow rate and temperature, and communicates with intelligent sensors through the HART protocol to obtain real-time equipment status and diagnostic information.

Chemical engineering and pharmaceuticals: Precisely measure and control key parameters in the reaction process, such as liquid level, pH value or concentration, to ensure production safety and product quality.

Water treatment and environmental monitoring: Collect analog signals from water quality sensors (such as turbidity and pressure), and manage remote devices in combination with the HART protocol.

Manufacturing industry

In an automated production line, it is used to monitor the operating status of motors, pumps or valves, control electromagnetic equipment or AC motors, and ensure production efficiency.

It is suitable for scenarios that require high-precision data collection, such as robot control or precision processing.

Energy Management

In power or renewable energy systems, monitor current, voltage or power parameters to optimize energy distribution and equipment operation.

The HART protocol supports remote calibration and maintenance, reducing on-site intervention.

Complex industrial environment

The overvoltage protection and isolation design of the module makes it suitable for use in environments with high electrical noise, such as heavy industry or metallurgical plants.

The open shell design is suitable for installation in a well-ventilated control cabinet and can adapt to various industrial site conditions.

Distributed Control System (DCS) : Integrated into the ControlLogix platform, it realizes distributed signal acquisition and control through EtherNet/IP or ControlNet networks, and is suitable for complex control architectures in large factories.
