Functional Features

Digital signal output: It can output the digital signals of the control system to external devices. Common output signals include control

commands such as on/off, valve on/off, etc.

High redundancy design: Compatible with the Triple Redundancy (TMR) configuration of the Triconex system, each TMR digital output

module has three independent electronic channels to ensure stable system operation in the event of module failure.

High Security: Compliant with SIL3 safety standards, suitable for control systems with high reliability and safety requirements.

Hot swappable function: Supports hot plugging, facilitating module maintenance, expansion, and replacement, reducing downtime.

Multi channel output: Provides multiple output channels to control multiple external devices simultaneously, enhancing system flexibility.

Strong diagnostic function: It has comprehensive diagnostic functions and can detect and report various faults, such as adhesion of output

points, switch faults, etc.

Applicable substrates

Model 2401: Used for typical applications.

Model 2401L: Used for low current applications that require integrated current limiting, each output is equipped with a 180 ohm series resistor.

DO External Terminal Board: Used for relay output external terminal panels in high-voltage applications, or for hazardous location external

terminal panels with model number 9671-610.

application area

Safety Instrumented System (SIS): Used to perform safety control tasks such as Emergency Shutdown (ESD) or other safety operations.

Process control system: used to control equipment such as valves, pumps, actuators, etc., to ensure the smooth operation of the production

process.

Automation control: Used for switch control of actuators in automation equipment, commonly found in industries such as chemical, petroleum,

and natural gas.
