peripherals will require an Expansion Bus Power Supply which connects as the
first module on the Expansion Bus.
Users will set the address dial of the Expansion Digital Module to a unique digital
module address number (1-4). If the Expansion Digital Module is the last device
on the Expansion Bus, set the address to the address value that enables in the
internal terminating resistor (1T-4T). A power cycle is required when changes
are made to the address dial.
Users will set the address dial of the Expansion Analog Module to a unique
analog module address number (1-4). If the Expansion Analog Module is the last
device on the Expansion Bus, set the address to the address value that enables in
the internal terminating resistor (1T-4T). A power cycle is required when
changes are made to the address dial.
Users will connect the E300 Base Relay to the Expansion Module’s Input Port
using the supplied Expansion Bus cable. Users will add the next Expansion
Module by connecting the supplied Expansion Bus cable to the Output Port of
the previous Expansion Module and into the Input Port of the additional
Expansion Module. The Operator Stations is the last device on the E300
Expansion Bus; it only has an Input Port with an internal Expansion Bus
terminating resistor.
If the user supplied Expansion Bus cable is not long enough for the installation,
1-meter (Cat. No. 193-EXP-CBL-1M) and 3-meter (Cat. No.
193-EXP-CBL-3M) Expansion Bus cables are available as accessories. The E300
expansion bus can support a maximum distance of 5 meters (16 ft.).
