• One Transceiver Module.
• One Power Amplifier Module.
• One Power Supply Module.
• One Interface Module (Optional - depending on external interfaces).
A dual-channel DRB-25 requires one Controller Module and the following plug-in modules:
• Two Transceiver Modules.
• Two Power Amplifier Modules.
• Two Power Supply Modules.
• One Interface Module (Optional - depending on external interfaces).
A single-channel DRB-25 can be easily and inexpensively converted to a dual-channel DRB-25 by the
installation of the additional modules.
The DRB-25 may be configured for AC or DC power sources, or as AC power with DC revert in the case of
AC power failure.
A block diagram of a DRB-25 is shown in Figure 1-3.
