Elevator Interface Control PCBA Board

The Elevator Interface Control PCBA is developed for signal routing, interface expansion, and peripheral device connection in elevator control systems. It serves as an intermediate control board between the main controller and external equipment, supporting multi-channel signal transmission, I/O expansion, relay-based switching, and organized wiring distribution across elevator subsystems. A series of multi-pin connectors is arranged across the PCB to simplify connections with wiring harnesses, control modules, and other external devices. Multiple onboard relays switch designated output channels, while fuse holders, capacitors, resistors, protection components, terminal blocks, and board-to-board connectors support power distribution, signal conditioning, and circuit protection. Clearly marked interfaces, including H1-H13 as well as CA, CB, and CC, make connection groups easier to identify during manufacturing, installation, troubleshooting, and maintenance. Production uses a combina…
