Power Supply
ComTroll 230 requires 12Vdc supply voltage with a battery backup. It can be solar charged in
configurations with up to three RTU cards. (With radio communication only).
SLC-200+ is the standard DC/DC regulator where external 12Vdc is available. This is also a
battery charger for the backup battery, both when external DC is connected and when a solar
panel is connected.
The SLC-200+ can be replaced with DC/DC-1, a regulator unit for input voltages between 18-
36 Vdc and 36-72 Vdc.
Connections
ComTroll 230 uses two different backplanes, 06310a and 06315a.
06310a covers the SLC-200+ (or DC-DC-1), the CRU-200 and one RTU-30 card.
Each additional RTU-30i card in a rack needs a separate backplane. The RTU-cards are tied
together on the Local Bus Bridge Cable, where also supply voltage is transferred to the next
unit.

A ribbon cable connects between each RTU-30 and the RIM 1, Relay Interface Module. For
details about the RIM 1, please refer to separate documentation.
Main backplane, 06310a
J1:
12Vdc OUTPUT, from the SLC-200+. J1 can also be used as a 12Vdc input when the
SLC-200+ is not mounted.
J5:
12V battery input
J6:
External DC input from solar panel or external DC source. Max voltage: 24Vdc
J9:
DC input only used when DC/DC-1 regulator is mounted.
J10:
Twisted Pair Bus. (TP/XF-78 or TP/FT-10)
