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).
