Function

High-precision voltage output

Provide ±10.5V DC voltage signal for driving analog equipment or actuators.

High resolution (14-bit) ensures precise output control and is suitable for high-precision adjustment scenarios.

Channel isolation

Each output channel is completely isolated (between channels and between channels and the backplane) to avoid interference, making it suitable for high-noise environments.

Isolation design enhances signal integrity and system reliability.

Fault and Condition Monitoring

It provides overvoltage protection (24V DC) and short-circuit protection (electronic current limiting) to ensure the safety of the module.

The status data is sent to the main controller through the multicast function, supporting real-time monitoring.

Supports timestamp functionality and is suitable for Event sequence (SOE) applications.

Real-time data processing

Support real-time channel sampling and data alarm.

The module supports the automatic generation of labels by Studio 5000 Logix Designer, simplifying programming and data access.

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).

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, frequency converters (VFDS) or recorders to control voltage signals to regulate parameters such as flow and pressure.

Chemical engineering and pharmaceuticals: Control actuators, adjust the voltage during the reaction process to drive equipment (such as potentiometers, servo controllers), and ensure process accuracy.

Water treatment: Drive analog instruments or control systems to adjust the operating parameters of water treatment equipment.

Manufacturing industry

It is used to control servo motors, proportional valves or voltage-driven equipment to optimize the speed and efficiency of the production line.

It is suitable for scenarios that require precise voltage output, such as robot control or precision machining.

Energy Management

In power or renewable energy systems, voltage signals are controlled to regulate generators or distribution equipment.

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.
