Door control

The expander enables distribution of power and RS485 communication bus to two doors. For each door
the EXP2D/4D offers 1.0A power supply output (VDR+ and VDR- terminals), 0.2A power supply output
(TML+ and TML- terminals), communication bus (RS485 A and B terminals), two programmable inputs
(DC and DR) and two programmable outputs (LCK and BELL). The 1.0A output is dedicated to supply
door lock and door related devices (e.g. alarm signalling device). The 0.2A output is dedicated to supply
readers. Short circuit at any power supply output or RS485 bus does not affect other outputs. In the figure
below a typical read-in/read-out door control scenario with EXP2D/4D expander is presented. The door
system is supplied from the expander and it includes:
15. 2 x AC-MAXxx readers (RS485)
