Radeus Labs-CP/LP Polarization Controller

The Radeus Labs RL250 is a 1RU rack-mount polarization controller that independently drives two polarization switch motors, selecting circular polarization (CP) or linear polarization (LP) on each feed when commanded. The RL250 connects to the indoor unit (IDU) over TCP/IP Ethernet, executes polarization change commands, and reports the current polarization selection status of each switch back to the IDU.

Key Features

• Independent CP/LP selection for two polarization switch motors (POL 1 and POL 2).
• Positive polarization position feedback via switch indicator contacts, reported to the IDU.
• Compatible with standard and latching (Circuit #2) polarization switch motor circuits.
• IEC 320-C14 inlet with internal 24 VDC supply and forced-air cooling.
