The '''MRBD''' relay board has six relays, which are controlled by [[RCO]]'s from the exchnage or from a [[RIO]] unit. The MRBD must be powered by +24 VDC. The AlphaCom E7 and E20 comes with a 24VDC outlet for such purpose, but in the AlphaCom E26 a [[PDB|Power Distribution Board PDB]] is required.

The RCOs can be activated by a high or low level. This is determined by jumper setting on the board. High level is used in AlphaCom installations, while low level is used in TouchLine Compact installations.

** 1,25A is maximum carrying current, maximum switching current at 125VAC is 0,5A. (approx. 60W).
  
In the AlphaCom exchange it is recommended that all the RCOs be connected to the same ASLT board(s) in order to simplify cabling.

Connectors and switches on MRBD board


The jumpers S1-S6 determine if the RCO should be activated by a high or low level. High level is used in AlphaCom system, while low level was used in the previous TouchLine generation of intercom system.

Connections

AlphaCom XE7

In the XE7 the cable is connected to the 8-pin pinheader labeled RCO 1-6 or RCO 7-12.

  • An ASLT board in board position 1 is required to operate RCO 1 - 6.
  • An ASLT board in board position 2 is required to operate RCO 7 - 12.
