Overview of 1756 ControlLogix Digital I/O Modules

The 1756 ControlLogix Digital I/O Modules provide several features that make them versatile and reliable. They offer a range of voltage options and can handle from 8 up to 32 points per module. They also come in isolated and non-isolated versions for flexibility based on system needs. Fault states are provided at the point level for output, ensuring better diagnostics and troubleshooting. The communication options available are direct-connect and rack-optimized options, depending on the application.

Key Features of 1756 ControlLogix Analog I/O Modules

The 1756 ControlLogix Analog I/O Modules include a variety of options such as input, output, and combination modules. For temperature measurements, thermocouple and RTD modules are available. Some of the standout features include on-board data alarming, scaling to engineering units, and real-time channel sampling. Configuration is flexible, with options for voltage, current, or 2-wire transmitter current sourcing on a per-channel basis.

Note: As of March 31, 2017, the 6-channel isolated analog I/O modules will be discontinued. Customers are encouraged to transition to the 8-channel versions.

Specialty I/O Modules for ControlLogix

The 1756 ControlLogix Specialty I/O Modules provide additional functionality, including configurable flow meter modules, high-speed counter modules, and programmable limit switch modules. These modules offer specialized control for industries requiring advanced I/O solutions.

Removable Terminal Blocks (RTBs) for Easy Interconnection

The 1756 Removable Terminal Blocks (RTBs) offer a flexible and efficient way to connect plant wiring to I/O modules. With options for screw-clamp or spring-clamp terminations, these terminal blocks are designed to be ordered separately from I/O modules.

HART Analog Isolated I/O Modules

The 1756 HART Analog Isolated I/O Modules come with channel-to-channel isolation, which enhances system reliability. Each channel includes a HART modem for faster data updates, and the modules support basic field device configuration via the Add-on Profile. These modules are designed to eliminate the need for field isolating barriers, making them a valuable addition to any system.

Enhanced Analog I/O Modules for Precision

The 1756 Enhanced Analog I/O Modules offer improved accuracy, repeatability, and stability. These isolated 8-channel and non-isolated 12- and 16-channel modules are designed for high precision and do not require field calibration. They feature a 24-bit design for advanced precision and come with per-channel status and fault LED annunciation. The modules also support SIL 1, systematic capability 2, and are certified for use in a ControlLogix SIL 2 architecture.

ControlLogix Communications Modules

The 1756 Communications Modules are essential for network-based access control. These modules provide encryption to secure important information shared between controllers and servers, preventing tampering and unauthorized access. They also offer enhanced security features for users, devices, and networks within the 1756 chassis.

Recommended Models

By offering a broad array of features and configurations, the 1756 ControlLogix I/O Modules provide excellent solutions for a wide range of industrial applications. Whether you are handling digital, analog, or specialty I/O requirements, these modules can meet your needs efficiently and reliably.
