32-Bit Standard Serial Main Controller Board

The main controller board is equipped with a 32-bit industrial ARM processor, and comes with dual-CPU to ensure improved system safety. It offers strong anti-interference and anti-static capabilities and passed the test for contact discharge up to 8000V. The 32-bit standard serial main controller board is manufactured according to EN81 and GB7588 safety rules, and is ideal for control of elevators in commercial buildings and residential buildings up to 64 floors. It helps ensure smooth, steady, accurate and comfortable elevator running. The maximum elevator speed is up to 4m/s.

The serial main controller board supports CAN bus communication and hence supports weight compensation system with CAN bus interface. STEP handheld elevator controller can also be connected to the main controller board. The main controller board also supports functions such as remote monitoring, elevator car performance test, and control of both asynchronous and synchronous traction motor. And it is compatible with encoders with differential, open collector, or pull-push outputs. It can keep maximally 20 historic records for elevator failures.

With IC card intelligent managejment function, the main controller board can be integrated into a Building Management System for building security monitoring use. It also supports remote monitoring function. With isolated CAN transceiver, the main controller board offers reduced electromagnetic interference susceptibility while being used for building security monitoring system.
