It is possible to define a per user access control policy. Each unit comes with six inputs and four outputs. Inputs can be configured to be analog and digital. Number of inputs and outputs can be extended by connecting additional units via RS485 and Ethernet. Programmable logic control allows the creation of automatic logic based on inputs, user activities and outputs.
