uLINK RELAY6 and uLINK RELAY10 are most commonly used uLINK network modules. They provide relay
contact outputs. These modules are used for any device that requires simple control – switch input to ground,
connect it to defined voltage, or connect two input ports together. The bottom row of LEDs show which contacts
are active (closed).
IMPORTANT: With uLINK RELAY10 always remember - in the sourcing configuration, power is supplied by the
module power source. The power supply must be capable of providing the necessary current. The +12 OUT
output is internally limited to 1.3A with electronic fuse.
IMPORTANT: Don't forget to connect the uLINK module to the central ground point in the shack or nearest
ground point in the setup if used in field.
IMPORTANT: Never exceed contact ratings, improper use and burned relays are not covered by warranty!

Connecting uLINK hardware: uLINK RELAY6/10
uLINK RELAY6 has six (6)
isolated SPST contacts 1 – 6
located at top terminal. Each
contact is rated 3A @ 125VAC
or 30VDC. The left (GND)
terminal is connected to the
Earth pin of bottom terminal.
This module should be used for
interface devices with low pin
control ports, AC/DC controlled
devices (like K9AY controller or
Ameritron RCS-4) or low pin
sinking control boxes (like Top Ten Devices antenna switches).
uLINK RELAY10 has ten (10) separate relay contacts 1 - 10 and one common
pole C located at top terminal. Each contact is rated 3A @ 125VAC or 30VDC.
The Left terminal, +12 OUT, is connected to the positive input (+13.8V) on the
bottom terminal and GND is connected to the Earth pin of the bottom terminal.
The relay common can be connected by jumper to the GND terminal pin for
sinking outputs ("switch to ground") or to +12 OUT for source outputs. If the
device to be controlled requires a different control voltage a separate power
supply can be connected to the C and GND terminal. This module can be used
with almost all antenna switches on the market including microHAM switches (of
course) as well as those be DX Engineering or Array Solutions.
