SECTION 1.0 COMMUNICATIONS
Addressable Relays are one form of communication
module used for remote control of electrical devices.
They are connected to an INCOM network that is part of
Eaton’s Cutler-Hammer PowerNet System. A typical
motor starter application is shown in Figure 2. A typical
network consists of twisted pairs, daisy-chained as shown
in Figure 3 to a remote personal computer. The computer
identifies which device on the network it is communicat-
ing with by the address assigned to the Addressable
Relay.
SECTION 2.0 INSTALLATION
This industrial type control is designed to be installed,
operated and maintained by adequately trained work
personnel. These instructions do not cover all details,
variations or combinations of the equipment, its storage,
delivery, installation, check-out, safe operation or mainte-
nance. Care must be exercised to comply with local,
state and national regulations, as well as safety practices,
for this class of equipment.
SECTION 3.0 CONTROL STATION
The control station for the PowerNet system must be an
IBM personal computer or equivalent (compatible) or a
translator unit that will accept the INCOM network signals
and convert them to an RS-232 format for transmission to
the controlling computer.
The Addressable Relay II can communicate at either 1200
baud or 9600 baud. The baud rate is used selectable in
the field by a DIP switch in the front of the unit. When
DIP switch 1 is set to the OFF position, the Addressable
Relay II will communicate at 9600 baud. When DIP
switch 1 is set to the ON position, the Addressable Relay
II will communicate at 1200 baud. See Figure 4 for DIP
switch configuration. All devices on a single INCOM
network must communicate at the same baud rate.
SECTION 4.0 THE ADDRESSABLE
RELAY II
The Addressable Relay II is a Form C relay with output
contact ratings as shown in Table 1. The Addressable
Relay II may be powered by 48 to 144 Volts ac or 48 to
125 Volts dc through terminals 11 and 12 of the terminal
