Industry: ABB LD series (low-voltage drive and automation components)

Model: LDMTR-01 (part number 63940135F)

Type: digital/analog mixed I/O module

Core application: signal acquisition and output control of industrial automation system.

Digital input (DI) supports dry contact/wet contact signals (such as buttons and limit switches). The number of channels needs to be checked in the manual (typically 8~16 channels). Digital output (DO) relays or transistor outputs (such as control contactors and indicator lights) and the load capacity needs to be confirmed (2A/250VAC).

Analog input (AI) optional voltage (0-10V) or current (4-20mA) signal set (if supported by the module) communication interface may integrate PROFIBUS-DP, Modbus RTU and other protocols (the specific model needs to be verified).

Motor control box: expand the I/O points of PLC and connect local sensors and actuators.

Matching of frequency converter: integrated with ABB ACS series frequency converter to realize start/stop/speed command transmission.

Production line automation: used for signal interaction between packaging machine and conveyor belt (such as photoelectric switch →PLC→ motor).

Abb dsqc (distributed system quality control) series power modules are specially designed for industrial automation and robot systems, and have many special functions to ensure high reliability, precise control and energy efficiency.

Application scenario

Robot servo drive: When moving at high speed, the sudden change of motor load may lead to voltage drop, and the dynamic adjustment of DSQC power supply ensures that the control system is not affected.

Spraying robot: keep the stable power supply of solenoid valve and metering pump to avoid uneven spraying caused by voltage fluctuation.

Energy saving effect

In frequent start-stop applications (such as handling robots), energy consumption can be reduced by 15%~25%.

Reduce the use of braking resistors and reduce the heat dissipation requirements.

Functional principle

By integrating sensors and algorithms, DSQC power supply realizes:

Temperature monitoring: NTC thermistor monitors the temperature of key devices (such as IGBT, capacitor) in real time, and runs at derating when it is over temperature.

Life prediction: Based on the change trend of ESR (equivalent series resistance) of electrolytic capacitor, the remaining life is estimated.

Fault record: store the latest 100 abnormal events (such as overcurrent and short circuit) for easy analysis afterwards.

Safety

Meaning of safety instructions Safety instructions are used to highlight a potential hazard when working on the equipment. Safety instructions must be strictly followed! Noncompliance can jeopardize the safety of personnel, the equipment and the environment.

DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.

WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.

NOTICE is used to address practices not related to personal injury. The safety instructions are derived from the following standards:– ISO 3864-2:2004 (E) Graphical symbols – Safety colors and safety signs – Part 2: Design principles for product safety labels– ANSI Z535.6 American National Standard for Product Safety Information in Product Manuals, Instructions, and Other Collateral Materials .
