IDM ZHD01-028 Mitsubishi Elevator Intercom Digital Concentrator/Divider User Manual

IDM ZHD01-028Elevator Intercom Digital Concentrator (also known as Elevator Intercom Divider) is a dedicated centralized device designed for use with the ZHD01-006 local intercom communication interrupter. It enables:

1. One Mitsubishi intercom host to connect with multiple remote devices,

2. Extended transmission distance for remote devices.

3. When transmitting elevator intercom signals via fiber optics, the signal impedance at the optical terminal output is low and the signal amplitude is small. Using this concentrator can significantly improve audio transmission quality.

1. Device Features:

1. Powered by 5V DC supply;

2. One board supports 1 to 8 expansion channels; each expansion port can connect multiple elevators;

3. Supports parallel operation of multiple boards; any number of boards can be connected in parallel without affecting system performance. When used with the IDM-120N chassis, up to 12 boards support hot-swap, enabling up to 128 remote interfaces. When used with a centralized chassis, centralized network management is supported;

4. Single board can operate independently and supports configuration via Bluetooth interface on mobile devices;

5. Each branch interface allows configuration of the connected terminal’s number.
