Elevator Controller device (ECD)
The Elevator Controller Device is a stripped down version of the DCD. It is used for interfacing different reader technologies to the ECU. Up to 10 ECD’s can be connected to the ECU’s on a single site. Each ECD is home run back to a particular ECU and more than one ECD can be connected to the same ECU. In most cases the ECD and the reader reside on the elevator car. Electronics Division

ECD Spec’s Input: 9 to 14 VDC (ECD will not operate below 9 volts)
AC/DC Transformer (ILCO P/N ) 9-14 Volts regulated DC, 500 mA Transformer OR Local Power Supply. OR powered from SCU power supply. Current: 100 ma (worst case current draw, board only) Data Storage: None (Found on the ECU) Operational Temperature: 14F to 104F (-10C to 40C)

ECD Tech Notes Up to ten ECD’s can be connected to the Local Data Trunk port of any ECU within a single SCU network. Power for the ECD should be derived from an AC to DC converter transformer (P/N ) or a power supply. This will reduce the number of conductors that have to added to the elevator travel cable. The ECD does not have a U3 RAM chip on-board. All memory functions are located on the ECU and not on the ECD. The ECD does not come with a enclosure, make sure you order one.
