User manual for ABB low‑voltage digital expansion modules covering digital, analog, leakage‑protection, hotspot, wireless temperature modules and sensors.
This manual provides technical function descriptions, installation, configuration and usage instructions for ABB low‑voltage system digital solution expansion modules. It covers digital I/O modules (MB550/MB551), analog I/O module (MA552), leakage‑protection relay (MR580), hotspot monitoring (MT561), wireless temperature module (MT564) and wireless temperature sensor (WT01).
The document includes safety symbols, terminology, wiring diagrams, parameter settings through the main controller (MC510/FC61x/FC710), and a detailed technical‑parameter appendix for each module. This manual is written in Chinese.
