IP to Relay Command Converter for Velocity Control System
AT-VCC-RELAY-KIT
The Atlona AT-VCC-RELAY-KIT is an accessory for the Atlona Velocity™ Control System that
provides conversion between IP control commands and relay / sensor signals. This Velocity
Control Converter is very compact and can be placed anywhere a device requires control and
is not IP-capable. The VCC-RELAY-KIT is remotely powered through Power over Ethernet (PoE),
or locally from a USB power source. The primary unit installs onto any surface via a convenient
mounting dock. A simple “click” locks it into place for a secure, reliable installation. The control
port module supports DIN rail installation, and features four relay outputs plus four sensor inputs.
The inputs and outputs are both congurable for various operating modes.

Operating Notes
• The Velocity Command Converter must be on the same network as the Velocity Gateway
(AT-VGW-250) or it will be unable to sync for control.
• The AT-VCC-RELAY-KIT is PoE, to power the unit, simply plug it into a PoE compatible
network switch. If the network switch is not PoE capable, a PoE injector (purchased separately)
or USB can be used.
• All devices (AT-VCC, Velocity, AT-VTP, switchers, etc) should be set to static IPs or the
DHCP IP address reserved for each individual device.
IMPORTANT: Velocity Gateway (AT-VGW-250) must be set up before the AT-VCC-RELAYKIT is fully functional.

Relay
The relay has 4 terminals which vary in function depending on how the jumpers above the ports
are set.
NOTE: Relays can only work up to a maximum of 24V and 500 mA current.
Single Pole, Single-Throw (SPST)
Place the jumpers as shown below, this can be done to a single connector or to both to create up
to 4 independent relays.

Double Pole, Double-Throw (DPDT)
When DPDT is selected within Velocity, it will create 2 relays that work simultaneously. If one
port is opened, the other will open at the same time. The DPDT is a variant of the SPDT and the
jumpers must be placed exactly as below to work.

Sensor
The ports can be set to sense either voltage or contact closure. Contact closure will react to the
change in current, while voltage will react to voltage as low as +/- 3V or as high as +/- 24V.
