IDM ZHD01

IDM ZHD01-028Elevator Intercom Digital Concentrator (also called Elevator Intercom Splitter) is a dedicated concentration device used in conjunction with the ZHD01-006 local intercom call interruption unit, enabling:

1. One Mitsubishi intercom master station to interconnect with more remote devices,

2. It can also be applied to extend the transmission distance of remote devices.

3. When fiber optic transmission is used for elevator intercom signals, due to the low output signal impedance and small signal amplitude of the optical terminal, the use of this concentrator can improve the sound transmission effect.

1. Features of this device:

1. Powered by a 5V power supply;

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

3. Supports parallel operation of multiple boards; any number of boards in parallel does not affect system performance. When using the IDM-120N chassis, 12 boards can be hot-swapped, supporting 128 remote interfaces. When using the centralized chassis, centralized network management is supported;

4. A single board can also work independently and supports configuration via a Bluetooth interface on a mobile phone;

5. The number of the connected terminal can be configured on each branch interface.
