Input impedance: Current 250 Ω, voltage >10 MΩ.

HART Function:

Support HART 5, 6 and 7 protocols.

Each channel can collect the process variables (PV, SV, TV, QV) and diagnostic data of the HART device.

HART scanning time: approximately 10 to 30 seconds (depending on device and network configuration).

Power supply:

Backplane power supply: 5.1V DC (maximum 300 mA), 24V DC (maximum 100 mA, HART power supply).

Power consumption: Approximately 4.5W (backplane power consumption).

Heat dissipation: approximately 15.35 BTU/hr.

Accuracy and Performance

Calibration accuracy: better than 0.1% (full scale, 25°C).

Temperature drift: ±50 ppm/°C (typical value).

Data refresh rate: 10-100 ms per channel (with visual filtering Settings).

Isolation: 250V isolation between channels, 250V isolation between channels and backplanes.

Correspondence:

Communicate with the controller via the ControlLogix backplane (supporting 1756-L7x and L8x controllers).

Support the RSLogix 5000/Studio 5000 configuration and install the Add-On Profile (AOP) of Spectrum Controls.

Environmental requirements:

Operating temperature: 0°C to 60°C

Storage temperature: -40°C to 85°C.

Working humidity: 5% to 95% (non-condensing).

Operating impact: 30G Operating vibration: 2G (10-500 Hz).

Installation: Insert into the ControlLogix rack (1756 series frame), which supports hot plugging and requires terminal blocks.

Certification: CE, UL, c-UL, FM, ATEX, Class I Division 2 Hazardous Location Certification.

Function

High-precision analog input: 8 differential channels support current (0-20 mA, 4-20 mA) and voltage (±10V) input, with 16-bit resolution, suitable for high-precision process measurement.

HART protocol support:

Communicate directly with HART intelligent devices to collect multi-variable (PV, SV, TV, QV) and device status/diagnostic information.

Supports point-to-point HART configuration without the need for an external multiplexer.

Advanced Diagnosis

Provide HART device status (such as fault, calibration status) and module health information (such as open circuit detection, over-range).

Support timestamp and alarm functions, integrated into Studio 5000.

Flexible configuration

Configure channel parameters (such as range, filtering, HART enabled) through the AOP of Studio 5000 and Spectrum Controls.

Support real-time data collection and online editing.

ControlLogix Integration:

Seamlessly integrated into the ControlLogix system, it communicates with the controller via the backplane and supports distributed I/O.

Hot-swappable function compatible with 1756 racks.

Isolation and Reliability

High-voltage isolation (250V) between channels and between channels and the backplane enhances the anti-interference capability.

Suitable for harsh industrial environments (0-60°C, IP20).

Scalability

It can be combined with other ControlLogix I/O modules to build large-scale control systems.

Application scenarios

Process control: It is used in industries such as petroleum and natural gas, chemical engineering, and pharmaceuticals, connecting HART transmitters (such as pressure, flow, and liquid level) to collect multi-variable data.

Distributed Control System (DCS) : Integrated into ControlLogix DCS, processes distributed analog signals, and communicates with HMI/SCADA.

Equipment management: Intelligent equipment management (such as valve positioner calibration and fault prediction) is achieved through the HART protocol.

Industrial Internet of Things (IIoT) : HART data is uploaded to the cloud platform through the ControlLogix controller, supporting predictive maintenance.
