X-18s™ Users Manual Installation and Connections
2.3 Making Connections
CAUTION: Make sure the power is shut off before making connections
CAUTION: This unit should be installed by a qualified technician.
CAUTION: Miswiring or misconfiguration could cause permanent damage to the X-18s, the
equipment to which it is connected, or both.
Screw terminal connectors are provided for making the DC power connections. Connections to the
relays require 1/4” push on tab terminals. The Com, NC, and NO terminals are marked on the relay
housing. Use wire rated for 75ºC (min) for connections to the relays. Make certain the tab terminals are
tightly crimped with a suitable wire terminal crimper.
It is recommended that any load (device to be controlled) not be connected to the expansion modules
until after the X-600M has been configured and tested. By doing this, wiring and configuration mistakes
will not cause the load device to turn on unexpectedly.
2.3.1 Expansion Bus
The expansion bus allows for a family of expansion modules to be connected directly to the X-600M
without the need for an Ethernet switch. The expansion bus carries both communications and power and
is connected in a ‘daisy-chain’ configuration.
Expansion modules come in two different enclosure configurations:
• Small modules, such as the X-11s, X-12s, etc., are 1.4” wide, fully enclosed, and have a single
expansion bus connector. These modules are connected to each other with a single ribbon
cable which has multiple connectors, one connector for each module. Power is supplied to these
small modules from the X-600M through the expansion cable.
• Larger modules, such as the X-18s, are packaged using a DIN-rail circuit-board tray and have
two expansion bus connectors, one on each end. These modules are connected to each other
using a 5-inch “jumper” ribbon-cable connector which has one connector on each end. The
larger modules require power to be supplied through a separate power connector.
The X-18s comes with a 5-inch jumper type ribbon cable for making connections to the X-600M. These
jumper cables are also used to connect additional larger modules such as additional X-18s units. When
making connections between the X-18s and the smaller expansion modules, a ribbon cable with multiple
connectors can be used. These cables are available from
ControlByWeb.com and can be purchased
with the correct number of connectors to accommodate the number of expansion modules needed.
Due to the height difference between the larger modules, such as the X-18s, and the smaller modules,
purchase a cable with one extra connector to allow the required spacing between the X-18s and the
adjacent module. The photo in in section 2.2 (above) illustrates how to connect the X-18s. The photo
shows an X-600M (on the right) connected to an X-18s module using the ribbon cable that came with the
X-18s. To the left of the X-18s are two additional “small” expansion modules (X-12s and X15s). The X-
18s is connected to these modules using a multi-connector ribbon cable with four connectors. Due to the
height difference between the X-18s and the X-15s one connector is not used.
