Suggested calibration cycle: 12 months.

Working environment

Operating temperature: 0 to 60°C.

Installation method: ControlLogix rack, in combination with 1756-TBNH or 1756-TBSH detachable terminal blocks (RTB, 20 pins).

Open casing, it needs to be installed in a well-ventilated control cabinet.

Wiring requirements:

Recommended wire diameter: 0.33 to 2.1mm ² (22 to 14 AWG), use shielded copper wire, insulation class 105°C or higher, maximum insulation thickness 1.2mm.

Certification and Standards

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

The UPC code provided by some suppliers (such as AoteWell) : 10612598171863.

Function

High-precision current output

Provide 0-20 mA or 4-20 mA current signals for driving analog actuators or devices.

High resolution (13-16 bits) ensures precise output control, making it suitable for scenarios that require high-precision adjustment.

Channel isolation

Each output channel is completely isolated to avoid interference between channels, making it suitable for high-noise or complex electrical environments.

Provide higher signal integrity and system reliability.

Fault and Condition Monitoring

Supports open-circuit detection (current output), triggering an alarm when the output current is lower than 0.1mA.

Short-circuit protection limits the current to 21 mA to prevent module damage.

Fault and status data are sent to the main controller through the multicast function for real-time monitoring.

Real-time data processing

Support real-time channel sampling and data alarm.

It provides a rolling timestamp function and is suitable for event sequence (SOE) applications.

Flexible installation and maintenance:

Supports live plug and unplug (RIUP), facilitating module replacement and maintenance.

Simplify on-site wiring by using detachable terminal blocks (RTB).

Communicate with the ControlLogix controller via ControlNet or EtherNet/IP network, supporting a distributed control architecture.

Engineering unit scaling: Supports scaling the output signal to engineering units, simplifying user program design and debugging.

Application scenarios

Industrial Automation and Process Control

Oil and gas: Drive control valves or frequency converters (VFDS) to control parameters such as pipeline flow and pressure.

Chemical engineering and pharmaceuticals: Control actuators to regulate the liquid level, flow rate or concentration during the reaction process, ensuring process stability and product quality.

Water treatment: Drive water pumps or valves to control the flow or pressure of the water treatment system.

Manufacturing industry

It is used to control variable frequency drives, servo motors or pneumatic actuators to optimize the speed and efficiency of the production line.

It is suitable for scenarios that require precise simulation output, such as packaging machines or robot control.

Energy Management

In power or renewable energy systems, control the output signals of generators or distribution equipment to optimize energy distribution.

It is used for signal retransmission to recorders, indicators or data loggers to monitor system performance.

Complex industrial environment

The channel isolation design makes it suitable for use in environments with high electrical noise, such as metallurgical, mining or heavy industrial 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 output through EtherNet/IP or ControlNet network, suitable for the complex control architecture of large factories.
