Elevator car top board EC-CTB consists of nine digital signal inputs, one analog voltage signal input, five relay NO signal outputs, one relay NO/NC signal output, two digital signal IO terminal used to communicate with command board EC-CCB and the terminal used for CAN communication with EC100, EC3000 and elevator car display panel. It supports the RS232 communication mode used to communicate with upper PC.
Command board EC-CCB is the command board matched with elevator car top board EC-CTB. Each command board consists of 24 input and 22 output interfaces including 16 floor buttons and 8 function signals. It is in charge of the collection of button command and output of button indicator. The operation demands of 64 floors can be realized through cascading, while the operation demands of main/vice operation cabinet in the elevator car can be realized through parallel connection.
Call display panel is one of the important interfaces for the interaction between EC100, EC160 and EC300 controller and the user. It receives the call from passengers and displays current floor and running direction. The floor display panel can act as the elevator car display panel.
