The MRBD relay board has six relays, which are controlled by RCO's from the exchange 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 Power Distribution Board PDB is required.
In the AlphaCom exchange it is recommended that all the RCOs be connected to the same ASLT board(s) in order to simplify cabling.
The Multi-Relay board is supplied in an installation box that can be fastened onto the mounting rail on the connection field of the AlphaCom exchange, or mounted on the wall in any suitable position.
Features
- Equipped with 6 dual change over relays and relay drivers
- Runs on +24 VDC
- Accepts RCOs with high- or low-level switch setting on the board
- Connector for 6 RCOs + 2 GND reference signals
- Connects to the AlphaCom Subscriber Connection Board through a 1:1 cable
- Fastens onto mounting rail in AlphaCom exchange

Connectors and Switches
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.
