Elevator Terminal
Elevator Intercom Digital Concentrator/Splitter
Market demand analysis of Elevator Intercom Digital Concentrator/Splitter: Traditional elevator intercom systems use twisted pair cables for transmission. When there are multiple elevators, the twisted pairs are typically directly paralleled at the central end. Usually, up to 10 units can be paralleled. When the quantity increases, a 1-to-8 concentrator is commonly used, with each downstream port of the concentrator capable of paralleling six or seven remote units.

IDM DT1000
The IDM DT1000 Elevator Status Acquisition Controller includes a full-function access type and a standard-function access type. It is used for collecting and reporting elevator operation status, remote control and management of elevators, and emergency in-carriage call-for-help alarms. It can be applied to various aspects of smart elevators.

IDM NT202
The IDM NT202 (DT) Mitsubishi Elevator Digital Five-party Intercom Optical Terminal provides a dedicated digital five-party intercom interface card that matches the signaling of the five-party intercom, enabling five-party communication between the central office and the machine room, car, car top, and pit. Five-party intercom optical terminals include the 2-channel IDM NT202 (DT), 8-channel IDM ENT448 (DT), 30-channel IDM 30EN (DT), etc. They meet the signal transmission needs from elevator group machine rooms of different capacities to the central office monitoring room, and are also suitable for fiber access transmission when monitoring rooms are relocated or merged.

IDM
Both the Mitsubishi analog five-party intercom system (old model) and the Mitsubishi digital five-party intercom system (new model) use 24V power supply and signal transmission to achieve longer transmission distances over twisted pair cables. As twisted pair cables in communities are increasingly being replaced by fiber optics, the output signal voltage of optical terminals is typically 3~5V, resulting in weaker parallel connection capability at the central office end, which affects the number of remote units that can be driven. The IDM Elevator Five-party Intercom Signal Aggregation Terminal is a device that conditions the output signals of optical terminals to meet the parallel connection management requirements at the central office end. A single board can aggregate 8 channels of intercom signals, and multi-board cascading enables aggregation of 16 or 24 channels. At remote sites where conditions permit, a remote signal conditioning device can be used to combine the intercom lines of 4 elevators before connecting them to the optical terminal for transmission.
